+
+# 2. Create database calypso
+sudo -u postgres psql -c "CREATE DATABASE calypso OWNER calypso;"
+
+# 3. Grant privileges
+sudo -u postgres psql -c "GRANT ALL PRIVILEGES ON DATABASE calypso TO calypso;"
+
+# 4. Verify
+sudo -u postgres psql -c "\du" | grep calypso
+sudo -u postgres psql -c "\l" | grep calypso
+```
+
+### Atau menggunakan installer script:

+# Database Setup Complete
+**Tanggal:** 2025-01-09  
+**Status:** ✅ **BERHASIL**
+
+## Yang Telah Dibuat
+
+### ✅ User PostgreSQL: `calypso`
+- Status: ✅ **CREATED**
+- Password: `calypso_secure_2025` (disimpan di script, perlu diubah untuk production)
+
+### ✅ Database: `calypso`
+- Owner: `calypso`
+- Encoding: UTF8
+- Status: ✅ **CREATED**
+
+### ✅ Database Access: `bacula`
+- User `calypso` memiliki **READ ACCESS** ke database `bacula`
+- Privileges:
+  - ✅ CONNECT ke database `bacula`
+  - ✅ USAGE pada schema `public`
+  - ✅ SELECT pada semua tables (32 tables)
+  - ✅ Default privileges untuk tables baru
+
+## Verifikasi
+
+### User yang Ada:
+```
+bacula    | 
+calypso   | 
+```
+
+### Database yang Ada:
+```
+bacula    | bacula   | SQL_ASCII | ... | calypso=c/bacula
+calypso   | calypso  | UTF8      | ... | calypso=CTc/calypso
+```
+
+### Access Test:
+- ✅ User `calypso` bisa connect ke database `calypso`
+- ✅ User `calypso` bisa connect ke database `bacula`
+- ✅ User `calypso` bisa SELECT dari tables di database `bacula` (32 tables accessible)
+
+## Konfigurasi untuk Calypso API
+
+Update `/etc/calypso/config.yaml` atau set environment variables:
+
+```bash
+export CALYPSO_DB_PASSWORD="calypso_secure_2025"
+export CALYPSO_DB_USER="calypso"
+export CALYPSO_DB_NAME="calypso"
+```
+
+Atau di config file:
+```yaml
+database:
+  host: "localhost"
+  port: 5432
+  user: "calypso"
+  password: "calypso_secure_2025"  # Atau via env var CALYPSO_DB_PASSWORD
+  database: "calypso"
+  ssl_mode: "disable"
+```
+
+## Catatan Penting
+
+⚠️ **Security Note:**
+- Password `calypso_secure_2025` adalah default password
+- **WAJIB diubah** untuk production environment
+- Gunakan strong password generator
+- Simpan password di `/etc/calypso/secrets.env` atau environment variables
+
+## Next Steps
+
+1. ✅ Database `calypso` siap untuk migrations
+2. ✅ Calypso API bisa connect ke database sendiri
+3. ✅ Calypso API bisa read data dari Bacula database
+4. ⏭️ Jalankan Calypso API untuk auto-migration
+5. ⏭️ Update password ke production-grade password
+
+## Bacula Database Access
+
+User `calypso` sekarang bisa:
+- ✅ Read semua tables di database `bacula`
+- ✅ Query job history, clients, storage pools, volumes, media
+- ✅ Monitor backup operations
+- ❌ **TIDAK bisa** write/modify data di database `bacula` (read-only access)
+
+Ini sesuai dengan requirement Calypso untuk monitoring dan reporting Bacula operations tanpa bisa mengubah konfigurasi Bacula.

+# Dataset Mountpoint Validation
+
+## Issue
+User meminta validasi bahwa mount point untuk dataset dan volume harus berada di dalam directory pool yang terkait.
+
+## Solution
+Menambahkan validasi untuk memastikan mount point dataset berada di dalam pool mount point directory (`/opt/calypso/data/pool/<pool-name>/`).
+
+## Changes Made
+
+### Updated `backend/internal/storage/zfs.go`
+**File**: `backend/internal/storage/zfs.go` (line 728-814)
+
+**Key Changes:**
+
+1. **Mount Point Validation**
+   - Validasi bahwa mount point yang user berikan harus berada di dalam pool directory
+   - Menggunakan `filepath.Rel()` untuk memastikan mount point tidak keluar dari pool directory
+
+2. **Default Mount Point**
+   - Jika mount point tidak disediakan, set default ke `/opt/calypso/data/pool/<pool-name>/<dataset-name>/`
+   - Memastikan semua dataset mount point berada di dalam pool directory
+
+3. **Mount Point Always Set**
+   - Untuk filesystem datasets, mount point selalu di-set (baik user-provided atau default)
+   - Tidak lagi conditional pada `req.MountPoint != ""`
+
+**Before:**
+```go
+if req.Type == "filesystem" && req.MountPoint != "" {
+    mountPath := filepath.Clean(req.MountPoint)
+    // ... create directory ...
+}
+
+// Later:
+if req.Type == "filesystem" && req.MountPoint != "" {
+    args = append(args, "-o", fmt.Sprintf("mountpoint=%s", req.MountPoint))
+}
+```
+
+**After:**
+```go
+poolMountPoint := fmt.Sprintf("/opt/calypso/data/pool/%s", poolName)
+var mountPath string
+
+if req.Type == "filesystem" {
+    if req.MountPoint != "" {
+        // Validate mount point is within pool directory
+        mountPath = filepath.Clean(req.MountPoint)
+        // ... validation logic ...
+    } else {
+        // Use default mount point
+        mountPath = filepath.Join(poolMountPoint, req.Name)
+    }
+    // ... create directory ...
+}
+
+// Later:
+if req.Type == "filesystem" {
+    args = append(args, "-o", fmt.Sprintf("mountpoint=%s", mountPath))
+}
+```
+
+## Mount Point Structure
+
+### Pool Mount Point
+```
+/opt/calypso/data/pool/<pool-name>/
+```
+
+### Dataset Mount Point (Default)
+```
+/opt/calypso/data/pool/<pool-name>/<dataset-name>/
+```
+
+### Dataset Mount Point (Custom - must be within pool)
+```
+/opt/calypso/data/pool/<pool-name>/<custom-path>/
+```
+
+## Validation Rules
+
+1. **User-provided mount point**:
+   - Must be within `/opt/calypso/data/pool/<pool-name>/`
+   - Cannot use `..` to escape pool directory
+   - Must be a valid directory path
+
+2. **Default mount point**:
+   - Automatically set to `/opt/calypso/data/pool/<pool-name>/<dataset-name>/`
+   - Always within pool directory
+
+3. **Volumes**:
+   - Volumes cannot have mount points (already validated in handler)
+
+## Error Messages
+
+- `mount point must be within pool directory: <path> (pool mount: <pool-mount>)` - Jika mount point di luar pool directory
+- `mount point path exists but is not a directory: <path>` - Jika path sudah ada tapi bukan directory
+- `failed to create mount directory <path>` - Jika gagal membuat directory
+
+## Testing
+
+1. **Create dataset without mount point**:
+   - Should use default: `/opt/calypso/data/pool/<pool-name>/<dataset-name>/`
+
+2. **Create dataset with valid mount point**:
+   - Mount point: `/opt/calypso/data/pool/<pool-name>/custom-path/`
+   - Should succeed
+
+3. **Create dataset with invalid mount point**:
+   - Mount point: `/opt/calypso/data/other-path/`
+   - Should fail with validation error
+
+4. **Create volume**:
+   - Should not set mount point (volumes don't have mount points)
+
+## Status
+✅ **COMPLETED** - Mount point validation untuk dataset sudah diterapkan

+# MinIO Installation Recommendation for Calypso Appliance
+
+## Executive Summary
+
+**Rekomendasi: Native Installation** ✅
+
+Untuk Calypso appliance, **native installation** MinIO lebih sesuai daripada Docker karena:
+1. Konsistensi dengan komponen lain (semua native)
+2. Performa lebih baik (tanpa overhead container)
+3. Integrasi lebih mudah dengan ZFS dan systemd
+4. Sesuai dengan filosofi appliance (minimal dependencies)
+
+---
+
+## Analisis Arsitektur Calypso
+
+### Komponen yang Sudah Terinstall (Semuanya Native)
+
+| Komponen | Installation Method | Service Management |
+|----------|-------------------|-------------------|
+| **ZFS** | Native (kernel modules) | systemd (zfs-zed.service) |
+| **SCST** | Native (kernel modules) | systemd (scst.service) |
+| **NFS** | Native (nfs-kernel-server) | systemd (nfs-server.service) |
+| **SMB** | Native (Samba) | systemd (smbd.service, nmbd.service) |
+| **ClamAV** | Native (clamav-daemon) | systemd (clamav-daemon.service) |
+| **MHVTL** | Native (kernel modules) | systemd (mhvtl.target) |
+| **Bacula** | Native (bacula packages) | systemd (bacula-*.service) |
+| **PostgreSQL** | Native (postgresql-16) | systemd (postgresql.service) |
+| **Calypso API** | Native (Go binary) | systemd (calypso-api.service) |
+
+**Kesimpulan:** Semua komponen menggunakan native installation dan dikelola melalui systemd.
+
+---
+
+## Perbandingan: Native vs Docker
+
+### Native Installation ✅ **RECOMMENDED**
+
+**Pros:**
+- ✅ **Konsistensi**: Semua komponen lain native, MinIO juga native
+- ✅ **Performa**: Tidak ada overhead container, akses langsung ke ZFS
+- ✅ **Integrasi**: Lebih mudah integrasi dengan ZFS datasets sebagai storage backend
+- ✅ **Monitoring**: Logs langsung ke journald, metrics mudah diakses
+- ✅ **Resource**: Lebih efisien (tidak perlu Docker daemon)
+- ✅ **Security**: Sesuai dengan security model appliance (systemd security hardening)
+- ✅ **Management**: Dikelola melalui systemd seperti komponen lain
+- ✅ **Dependencies**: MinIO binary standalone, tidak perlu Docker runtime
+
+**Cons:**
+- ⚠️ Update: Perlu download binary baru dan restart service
+- ⚠️ Dependencies: Perlu manage MinIO binary sendiri
+
+**Mitigation:**
+- Update bisa diotomasi dengan script
+- MinIO binary bisa disimpan di `/opt/calypso/bin/` seperti komponen lain
+
+### Docker Installation ❌ **NOT RECOMMENDED**
+
+**Pros:**
+- ✅ Isolasi yang lebih baik
+- ✅ Update lebih mudah (pull image baru)
+- ✅ Tidak perlu manage dependencies
+
+**Cons:**
+- ❌ **Inkonsistensi**: Semua komponen lain native, Docker akan jadi exception
+- ❌ **Overhead**: Docker daemon memakan resource (~50-100MB RAM)
+- ❌ **Kompleksitas**: Tambahan layer management (Docker + systemd)
+- ❌ **Integrasi**: Lebih sulit integrasi dengan ZFS (perlu volume mapping)
+- ❌ **Performance**: Overhead container, terutama untuk I/O intensive workload
+- ❌ **Security**: Tambahan attack surface (Docker daemon)
+- ❌ **Monitoring**: Logs perlu di-forward dari container ke journald
+- ❌ **Dependencies**: Perlu install Docker (tidak sesuai filosofi minimal dependencies)
+
+---
+
+## Rekomendasi Implementasi
+
+### Native Installation Setup
+
+#### 1. Binary Location
+```
+/opt/calypso/bin/minio
+```
+
+#### 2. Configuration Location
+```
+/opt/calypso/conf/minio/
+  ├── config.json
+  └── minio.env
+```
+
+#### 3. Data Location (ZFS Dataset)
+```
+/opt/calypso/data/pool/<pool-name>/object/
+```
+
+#### 4. Systemd Service
+```ini
+[Unit]
+Description=MinIO Object Storage
+After=network.target zfs.target
+Wants=zfs.target
+
+[Service]
+Type=simple
+User=calypso
+Group=calypso
+WorkingDirectory=/opt/calypso
+ExecStart=/opt/calypso/bin/minio server /opt/calypso/data/pool/%i/object --config-dir /opt/calypso/conf/minio
+Restart=always
+RestartSec=5
+StandardOutput=journal
+StandardError=journal
+SyslogIdentifier=minio
+
+# Security
+NoNewPrivileges=true
+PrivateTmp=true
+ProtectSystem=strict
+ProtectHome=true
+ReadWritePaths=/opt/calypso/data /opt/calypso/conf/minio /var/log/calypso
+
+# Resource limits
+LimitNOFILE=65536
+LimitNPROC=4096
+
+[Install]
+WantedBy=multi-user.target
+```
+
+#### 5. Integration dengan ZFS
+- MinIO storage backend menggunakan ZFS dataset
+- Dataset dibuat di pool yang sudah ada
+- Mount point: `/opt/calypso/data/pool/<pool-name>/object/`
+- Manfaatkan ZFS features: compression, snapshots, replication

+
+## Installation Steps (Native)
+
+### 1. Download MinIO Binary
+```bash
+# Download latest MinIO binary
+wget https://dl.min.io/server/minio/release/linux-amd64/minio
+chmod +x minio
+sudo mv minio /opt/calypso/bin/
+sudo chown calypso:calypso /opt/calypso/bin/minio
+```
+
+### 2. Create ZFS Dataset for Object Storage
+```bash
+# Create dataset in existing pool
+sudo zfs create <pool-name>/object
+sudo zfs set mountpoint=/opt/calypso/data/pool/<pool-name>/object <pool-name>/object
+sudo chown -R calypso:calypso /opt/calypso/data/pool/<pool-name>/object
+```
+
+### 3. Create Configuration Directory
+```bash
+sudo mkdir -p /opt/calypso/conf/minio
+sudo chown calypso:calypso /opt/calypso/conf/minio
+```
+
+### 4. Create Systemd Service
+```bash
+sudo cp /src/calypso/deploy/systemd/minio.service /etc/systemd/system/
+sudo systemctl daemon-reload
+sudo systemctl enable minio.service
+sudo systemctl start minio.service
+```
+
+### 5. Integration dengan Calypso API
+- Backend API mengelola MinIO melalui MinIO Admin API atau Go SDK
+- Configuration disimpan di database Calypso
+- UI untuk manage buckets, policies, users
+
+---
+
+## Kesimpulan
+
+**Native Installation** adalah pilihan terbaik untuk Calypso appliance karena:
+
+1. ✅ **Konsistensi**: Semua komponen lain native
+2. ✅ **Performa**: Optimal untuk I/O intensive workload
+3. ✅ **Integrasi**: Seamless dengan ZFS dan systemd
+4. ✅ **Filosofi**: Sesuai dengan "appliance-first" dan "minimal dependencies"
+5. ✅ **Management**: Unified management melalui systemd
+6. ✅ **Security**: Sesuai dengan security model appliance
+
+**Docker Installation** tidak direkomendasikan karena:
+- ❌ Menambah kompleksitas tanpa benefit yang signifikan
+- ❌ Inkonsisten dengan arsitektur yang ada
+- ❌ Overhead yang tidak perlu untuk appliance
+
+---
+
+## Next Steps
+
+1. ✅ Implementasi native MinIO installation
+2. ✅ Create systemd service file
+3. ✅ Integrasi dengan ZFS dataset
+4. ✅ Backend API integration
+5. ✅ Frontend UI untuk MinIO management

+# MinIO Integration Complete
+
+**Tanggal:** 2026-01-09  
+**Status:** ✅ **COMPLETE**
+
+## Summary
+
+Integrasi MinIO dengan Calypso appliance telah selesai. Frontend Object Storage page sekarang menggunakan data real dari MinIO service, bukan dummy data lagi.
+
+---
+
+## Changes Made
+
+### 1. Backend Integration ✅
+
+#### Created MinIO Service (`backend/internal/object_storage/service.go`)
+- **Service**: Menggunakan MinIO Go SDK untuk berinteraksi dengan MinIO server
+- **Features**:
+  - List buckets dengan informasi detail (size, objects, access policy)
+  - Get bucket statistics
+  - Create bucket
+  - Delete bucket
+  - Get bucket access policy
+
+#### Created MinIO Handler (`backend/internal/object_storage/handler.go`)
+- **Handler**: HTTP handlers untuk API endpoints
+- **Endpoints**:
+  - `GET /api/v1/object-storage/buckets` - List all buckets
+  - `GET /api/v1/object-storage/buckets/:name` - Get bucket info
+  - `POST /api/v1/object-storage/buckets` - Create bucket
+  - `DELETE /api/v1/object-storage/buckets/:name` - Delete bucket
+
+#### Updated Configuration (`backend/internal/common/config/config.go`)
+- Added `ObjectStorageConfig` struct untuk MinIO configuration
+- Fields:
+  - `endpoint`: MinIO server endpoint (default: `localhost:9000`)
+  - `access_key`: MinIO access key
+  - `secret_key`: MinIO secret key
+  - `use_ssl`: Whether to use SSL/TLS
+
+#### Updated Router (`backend/internal/common/router/router.go`)
+- Added object storage routes group
+- Routes protected dengan permission `storage:read` dan `storage:write`
+- Service initialization dengan error handling
+
+### 2. Configuration ✅
+
+#### Updated `/opt/calypso/conf/config.yaml`
+```yaml
+# Object Storage (MinIO) Configuration
+object_storage:
+  endpoint: "localhost:9000"
+  access_key: "admin"
+  secret_key: "HqBX1IINqFynkWFa"
+  use_ssl: false
+```
+
+### 3. Frontend Integration ✅
+
+#### Created API Client (`frontend/src/api/objectStorage.ts`)
+- **API Client**: TypeScript client untuk object storage API
+- **Interfaces**:
+  - `Bucket`: Bucket data structure
+- **Methods**:
+  - `listBuckets()`: Fetch all buckets
+  - `getBucket(name)`: Get bucket details
+  - `createBucket(name)`: Create new bucket
+  - `deleteBucket(name)`: Delete bucket
+
+#### Updated ObjectStorage Page (`frontend/src/pages/ObjectStorage.tsx`)
+- **Removed**: Mock data (`MOCK_BUCKETS`)
+- **Added**: Real API integration dengan React Query
+- **Features**:
+  - Fetch buckets dari API dengan auto-refresh setiap 5 detik
+  - Transform API data ke format UI
+  - Loading state untuk buckets
+  - Empty state ketika tidak ada buckets
+  - Mutations untuk create/delete bucket

+# Permissions Fix Complete
+**Tanggal:** 2025-01-09  
+**Status:** ✅ **FIXED**
+
+## Problem
+
+User `calypso` tidak memiliki permission untuk:
+- Mengakses raw disk devices (`/dev/sd*`)
+- Menjalankan ZFS commands (`zpool`, `zfs`)
+- Membuat ZFS pools
+
+Error yang muncul:
+```
+failed to create ZFS pool: cannot open '/dev/sdb': Permission denied
+cannot create 'default': permission denied
+```
+
+## Solution Implemented
+
+### 1. Group Membership ✅
+
+User `calypso` ditambahkan ke groups:
+- `disk` - Access to disk devices (`/dev/sd*`)
+- `tape` - Access to tape devices
+
+```bash
+sudo usermod -aG disk,tape calypso
+```
+
+### 2. Sudoers Configuration ✅
+
+File `/etc/sudoers.d/calypso` dibuat dengan permissions:
+
+```sudoers
+# ZFS Commands
+calypso ALL=(ALL) NOPASSWD: /usr/sbin/zpool, /usr/sbin/zfs, /usr/bin/zpool, /usr/bin/zfs
+

+```
+
+### 3. Backend Code Updates ✅
+
+**Helper Functions Added:**
+```go
+// zfsCommand executes a ZFS command with sudo
+func zfsCommand(ctx context.Context, args ...string) *exec.Cmd {
+	return exec.CommandContext(ctx, "sudo", append([]string{"zfs"}, args...)...)
+}
+
+// zpoolCommand executes a ZPOOL command with sudo
+func zpoolCommand(ctx context.Context, args ...string) *exec.Cmd {
+	return exec.CommandContext(ctx, "sudo", append([]string{"zpool"}, args...)...)
+}
+```
+
+**All ZFS/ZPOOL Commands Updated:**
+- ✅ `zpool create` → `zpoolCommand(ctx, "create", ...)`
+- ✅ `zpool destroy` → `zpoolCommand(ctx, "destroy", ...)`
+- ✅ `zpool list` → `zpoolCommand(ctx, "list", ...)`

+## Problem
+
+User `calypso` tidak memiliki permission yang cukup untuk:
+- Mengakses raw disk devices (`/dev/sd*`)
+- Menjalankan ZFS commands (`zpool`, `zfs`)
+- Mengakses tape devices
+- Menjalankan SCST commands
+
+## Solution
+
+### 1. Group Membership
+
+User `calypso` telah ditambahkan ke groups berikut:
+- `disk` - Access to disk devices
+- `tape` - Access to tape devices  
+- `storage` - Storage-related permissions
+
+```bash
+sudo usermod -aG disk,tape,storage calypso
+```
+
+### 2. Sudoers Configuration
+
+File `/etc/sudoers.d/calypso` telah dibuat dengan permissions berikut:
+
+#### ZFS Commands
+```sudoers
+calypso ALL=(ALL) NOPASSWD: /usr/sbin/zpool, /usr/sbin/zfs, /usr/bin/zpool, /usr/bin/zfs
+```
+
+#### SCST Commands
+```sudoers

+```
+
+#### Tape Utilities
+```sudoers
+calypso ALL=(ALL) NOPASSWD: /usr/bin/mtx, /usr/bin/mt, /usr/bin/sg_*, /usr/bin/sg3_utils/*
+```
+
+#### System Monitoring
+```sudoers
+calypso ALL=(ALL) NOPASSWD: /usr/bin/systemctl status *, /usr/bin/systemctl is-active *, /usr/bin/journalctl -u *
+```
+
+## Verification
+
+### Check Group Membership
+```bash
+groups calypso
+# Output should include: disk tape storage
+```
+
+### Check Sudoers File
+```bash
+sudo visudo -c -f /etc/sudoers.d/calypso
+# Should return: /etc/sudoers.d/calypso: parsed OK
+```
+
+### Test ZFS Access
+```bash
+sudo -u calypso zpool list
+# Should work without errors
+```
+
+### Test Device Access
+```bash
+sudo -u calypso ls -la /dev/sdb
+# Should show device permissions
+```
+
+## Backend Code Changes Needed
+
+Backend code perlu menggunakan `sudo` untuk ZFS commands. Contoh:
+
+```go
+// Before (will fail with permission denied)
+cmd := exec.CommandContext(ctx, "zpool", "create", ...)
+
+// After (with sudo)
+cmd := exec.CommandContext(ctx, "sudo", "zpool", "create", ...)
+```
+
+## Current Status
+
+✅ **Groups:** User calypso added to disk, tape, storage groups  
+✅ **Sudoers:** Configuration file created and validated  
+✅ **Permissions:** File permissions set to 0440 (secure)  
+⏭️ **Code Update:** Backend code needs to use `sudo` for privileged commands
+
+## Next Steps
+
+1. ✅ Groups configured
+2. ✅ Sudoers configured
+3. ⏭️ Update backend code to use `sudo` for:
+   - ZFS operations (`zpool`, `zfs`)
+   - SCST operations (`scstadmin`)
+   - Tape operations (`mtx`, `mt`, `sg_*`)
+4. ⏭️ Restart Calypso API service
+5. ⏭️ Test ZFS pool creation via frontend
+
+## Important Notes
+
+- Sudoers file uses `NOPASSWD` for convenience (service account)
+- Only specific commands are allowed (security best practice)
+- File permissions are 0440 (read-only for root and group)
+- Service restart required after permission changes

+# Pool Delete Mountpoint Cleanup
+
+## Issue
+Ketika pool dihapus, mount point directory tidak dihapus dari sistem. Mount point directory tetap ada di `/opt/calypso/data/pool/<pool-name>` meskipun pool sudah di-destroy.
+
+## Root Cause
+Fungsi `DeletePool` tidak melakukan cleanup untuk mount point directory setelah pool di-destroy.
+
+## Solution
+Menambahkan kode untuk menghapus mount point directory setelah pool di-destroy.
+
+## Changes Made
+
+### Updated `backend/internal/storage/zfs.go`
+**File**: `backend/internal/storage/zfs.go` (line 518-562)
+
+Menambahkan cleanup untuk mount point directory setelah pool di-destroy:
+
+**Before:**
+```go
+// Mark disks as unused
+for _, diskPath := range pool.Disks {
+    // ...
+}
+
+// Delete from database
+_, err = s.db.ExecContext(ctx, "DELETE FROM zfs_pools WHERE id = $1", poolID)
+// ...
+```
+
+**After:**
+```go
+// Remove mount point directory (default: /opt/calypso/data/pool/<pool-name>)
+mountPoint := fmt.Sprintf("/opt/calypso/data/pool/%s", pool.Name)
+if err := os.RemoveAll(mountPoint); err != nil {
+    s.logger.Warn("Failed to remove mount point directory", "mountpoint", mountPoint, "error", err)
+    // Don't fail pool deletion if mount point removal fails
+} else {
+    s.logger.Info("Removed mount point directory", "mountpoint", mountPoint)
+}
+
+// Mark disks as unused
+for _, diskPath := range pool.Disks {
+    // ...
+}
+
+// Delete from database
+_, err = s.db.ExecContext(ctx, "DELETE FROM zfs_pools WHERE id = $1", poolID)
+// ...
+```
+
+## Mount Point Location
+Default mount point untuk semua pools adalah:
+```
+/opt/calypso/data/pool/<pool-name>/
+```
+
+## Behavior
+1. Pool di-destroy dari ZFS system
+2. Mount point directory dihapus dengan `os.RemoveAll()`
+3. Disks ditandai sebagai unused di database
+4. Pool dihapus dari database
+
+## Error Handling
+- Jika mount point removal gagal, hanya log warning
+- Pool deletion tetap berhasil meskipun mount point removal gagal
+- Ini memastikan bahwa pool deletion tidak gagal hanya karena mount point cleanup
+
+## Testing
+1. Create pool dengan nama "test-pool"
+2. Verify mount point directory dibuat: `/opt/calypso/data/pool/test-pool/`
+3. Delete pool
+4. Verify mount point directory dihapus: `ls /opt/calypso/data/pool/test-pool` should fail
+
+## Status
+✅ **FIXED** - Mount point directory sekarang dihapus saat pool di-delete

+# Pool Refresh Fix
+
+## Issue
+UI tidak terupdate setelah klik tombol "Refresh Pools", meskipun pool ada di database dan sistem.
+
+## Root Cause
+Masalahnya ada di backend - field `created_by` di database bisa null, tapi di struct `ZFSPool` adalah `string` (bukan pointer atau `sql.NullString`). Saat scan, jika `created_by` null, scan akan gagal dan pool di-skip.
+
+## Solution
+Menggunakan `sql.NullString` untuk scan `created_by`, lalu assign ke string jika valid.

+2. Pool ada di sistem ZFS: `zpool list` shows `default-pool`
+3. API sekarang mengembalikan pool dengan benar
+4. Frontend sudah di-deploy
+
+## Status
+✅ **FIXED** - Backend sekarang mengembalikan pools dengan benar
+

+# Refresh Pools Button
+
+## Issue
+UI tidak update secara otomatis setelah create atau destroy pool. User meminta tombol refresh pools untuk manual refresh.
+
+## Solution
+Menambahkan tombol "Refresh Pools" yang melakukan refetch pools dari database, dan memperbaiki createPoolMutation untuk melakukan refetch dengan benar.
+
+## Changes Made
+
+### 1. Added Refresh Pools Button
+**File**: `frontend/src/pages/Storage.tsx` (line 446-459)
+
+Menambahkan tombol baru di antara "Rescan Disks" dan "Create Pool":
+```typescript
+<button
+  onClick={async () => {
+    await queryClient.invalidateQueries({ queryKey: ['storage', 'zfs', 'pools'] })
+    await queryClient.refetchQueries({ queryKey: ['storage', 'zfs', 'pools'] })
+  }}
+  disabled={poolsLoading}
+  className="flex items-center gap-2 px-4 py-2 rounded-lg border border-border-dark bg-card-dark text-white text-sm font-bold hover:bg-[#233648] transition-colors disabled:opacity-50"
+  title="Refresh pools list from database"
+>
+  <span className={`material-symbols-outlined text-[20px] ${poolsLoading ? 'animate-spin' : ''}`}>
+    sync
+  </span>
+  {poolsLoading ? 'Refreshing...' : 'Refresh Pools'}
+</button>
+```
+
+**Features:**
+- Icon `sync` dengan animasi spin saat loading
+- Disabled saat pools sedang loading
+- Tooltip: "Refresh pools list from database"
+- Styling konsisten dengan tombol lainnya
+
+### 2. Fixed createPoolMutation
+**File**: `frontend/src/pages/Storage.tsx` (line 219-239)
+
+Memperbaiki `createPoolMutation` untuk melakukan refetch dengan `await`:
+```typescript
+onSuccess: async () => {
+  // Invalidate and immediately refetch pools
+  await queryClient.invalidateQueries({ queryKey: ['storage', 'zfs', 'pools'] })
+  await queryClient.refetchQueries({ queryKey: ['storage', 'zfs', 'pools'] })
+  await queryClient.invalidateQueries({ queryKey: ['storage', 'disks'] })
+  // ... rest of the code
+  alert('Pool created successfully!')
+}
+```
+
+**Improvements:**
+- Menambahkan `await` pada `refetchQueries` untuk memastikan refetch selesai
+- Menambahkan success alert untuk feedback ke user
+
+## Button Layout
+Sekarang ada 3 tombol di header:
+1. **Rescan Disks** - Rescan physical disks dari sistem
+2. **Refresh Pools** - Refresh pools list dari database (NEW)
+3. **Create Pool** - Create new ZFS pool
+
+## Usage
+User dapat klik tombol "Refresh Pools" kapan saja untuk:
+- Manual refresh setelah create pool
+- Manual refresh setelah destroy pool
+- Manual refresh jika auto-refresh (3 detik) tidak cukup cepat
+
+## Testing
+1. Create pool → Klik "Refresh Pools" → Pool muncul
+2. Destroy pool → Klik "Refresh Pools" → Pool hilang
+3. Auto-refresh tetap berjalan setiap 3 detik
+
+## Status
+✅ **COMPLETED** - Tombol Refresh Pools ditambahkan dan createPoolMutation diperbaiki

+# Refresh Pools UX Improvement
+
+## Issue
+UI refresh update masih terlalu lama, sehingga user merasa command-nya gagal padahal sebenarnya tidak. User tidak mendapat feedback yang jelas bahwa proses sedang berjalan.
+
+## Solution
+Menambahkan loading state yang lebih jelas dan feedback visual yang lebih baik untuk memberikan indikasi bahwa proses refresh sedang berjalan.
+
+## Changes Made
+
+### 1. Added Loading State
+**File**: `frontend/src/pages/Storage.tsx`
+
+Menambahkan state untuk tracking manual refresh:
+```typescript
+const [isRefreshingPools, setIsRefreshingPools] = useState(false)
+```
+
+### 2. Improved Refresh Button
+**File**: `frontend/src/pages/Storage.tsx` (line 446-465)
+
+**Before:**
+```typescript
+<button
+  onClick={async () => {
+    await queryClient.invalidateQueries({ queryKey: ['storage', 'zfs', 'pools'] })
+    await queryClient.refetchQueries({ queryKey: ['storage', 'zfs', 'pools'] })
+  }}
+  disabled={poolsLoading}
+  ...
+>
+```
+
+**After:**
+```typescript
+<button
+  onClick={async () => {
+    setIsRefreshingPools(true)
+    try {
+      await queryClient.invalidateQueries({ queryKey: ['storage', 'zfs', 'pools'] })
+      await queryClient.refetchQueries({ queryKey: ['storage', 'zfs', 'pools'] })
+      // Small delay to show feedback
+      await new Promise(resolve => setTimeout(resolve, 300))
+      alert('Pools refreshed successfully!')
+    } catch (error) {
+      console.error('Failed to refresh pools:', error)
+      alert('Failed to refresh pools. Please try again.')
+    } finally {
+      setIsRefreshingPools(false)
+    }
+  }}
+  disabled={poolsLoading || isRefreshingPools}
+  className="... disabled:cursor-not-allowed"
+  ...
+>
+  <span className={`... ${(poolsLoading || isRefreshingPools) ? 'animate-spin' : ''}`}>
+    sync
+  </span>
+  {(poolsLoading || isRefreshingPools) ? 'Refreshing...' : 'Refresh Pools'}
+</button>
+```
+
+## Improvements
+
+### Visual Feedback
+1. **Loading Spinner**: Icon `sync` berputar saat refresh
+2. **Button Text**: Berubah menjadi "Refreshing..." saat loading
+3. **Disabled State**: Button disabled dengan cursor `not-allowed` saat loading
+4. **Success Alert**: Menampilkan alert setelah refresh selesai
+5. **Error Handling**: Menampilkan alert jika refresh gagal
+
+### User Experience
+- User mendapat feedback visual yang jelas bahwa proses sedang berjalan
+- User mendapat konfirmasi setelah refresh selesai
+- User mendapat notifikasi jika terjadi error
+- Button tidak bisa diklik berulang kali saat proses berjalan
+
+## Testing
+1. Klik "Refresh Pools"
+2. Verify button menunjukkan loading state (spinner + "Refreshing...")
+3. Verify button disabled saat loading
+4. Verify success alert muncul setelah refresh selesai
+5. Verify pools list ter-update
+
+## Status
+✅ **COMPLETED** - UX improvement untuk refresh pools button

+# ZFS Pool Mountpoint Fix
+
+## Issue
+ZFS pool creation was failing with error:
+```
+cannot mount '/default': failed to create mountpoint: Read-only file system
+```
+
+The issue was that ZFS was trying to mount pools to the root filesystem (`/default`), which is read-only.
+
+## Solution
+Updated the ZFS pool creation code to set a default mountpoint to `/opt/calypso/data/pool/<pool-name>` for all pools.
+
+## Changes Made
+
+### 1. Updated `backend/internal/storage/zfs.go`
+- Added mountpoint configuration during pool creation using `-m` flag
+- Set default mountpoint to `/opt/calypso/data/pool/<pool-name>`
+- Added code to create the mountpoint directory before pool creation
+- Added logging for mountpoint creation
+
+**Key Changes:**
+```go
+// Set default mountpoint to /opt/calypso/data/pool/<pool-name>
+mountPoint := fmt.Sprintf("/opt/calypso/data/pool/%s", name)
+args = append(args, "-m", mountPoint)
+
+// Create mountpoint directory if it doesn't exist
+if err := os.MkdirAll(mountPoint, 0755); err != nil {
+    return nil, fmt.Errorf("failed to create mountpoint directory %s: %w", mountPoint, err)
+}
+```
+
+### 2. Directory Setup
+- Created `/opt/calypso/data/pool` directory
+- Set ownership to `calypso:calypso`
+- Set permissions to `0755`
+
+## Default Mountpoint Structure
+All ZFS pools will now be mounted under:
+```
+/opt/calypso/data/pool/
+├── pool-name-1/
+├── pool-name-2/
+└── ...
+```
+
+## Testing
+1. Backend rebuilt successfully
+2. Service restarted successfully
+3. Ready to test pool creation from frontend
+
+## Next Steps
+- Test pool creation from the frontend UI
+- Verify that pools are mounted correctly at `/opt/calypso/data/pool/<pool-name>`
+- Ensure proper permissions for pool mountpoints

+# ZFS Pool Delete UI Update Fix
+
+## Issue
+When a ZFS pool is destroyed, the pool is removed from the system and database, but the UI doesn't update immediately to reflect the deletion.
+
+## Root Cause
+The frontend `deletePoolMutation` was not properly awaiting the refetch operation, which could cause race conditions where the UI doesn't update before the alert is shown.
+
+## Solution
+Added `await` to `refetchQueries` to ensure the query is refetched before showing the success alert.
+
+## Changes Made
+
+### Updated `frontend/src/pages/Storage.tsx`
+- Added `await` to `refetchQueries` call in `deletePoolMutation.onSuccess`
+- This ensures the pool list is refetched from the server before showing the success message
+
+**Key Changes:**
+```typescript
+onSuccess: async () => {
+  // Invalidate and immediately refetch
+  await queryClient.invalidateQueries({ queryKey: ['storage', 'zfs', 'pools'] })
+  await queryClient.refetchQueries({ queryKey: ['storage', 'zfs', 'pools'] }) // Added await
+  await queryClient.invalidateQueries({ queryKey: ['storage', 'disks'] })
+  setSelectedPool(null)
+  alert('Pool destroyed successfully!')
+},
+```
+
+## Additional Notes
+- The frontend already has `refetchInterval: 3000` (3 seconds) for automatic pool list refresh
+- Backend properly deletes pool from database in `DeletePool` function
+- ZFS Pool Monitor syncs pools every 2 minutes to catch manually deleted pools
+
+## Testing
+1. Destroy pool through UI
+2. Verify pool disappears from UI immediately
+3. Verify success alert is shown after UI update
+
+## Status
+✅ **FIXED** - Pool deletion now properly updates UI

+# ZFS Pool UI Display Fix
+
+## Issue
+ZFS pool was successfully created in the system and database, but it was not appearing in the UI. The API was returning `{"pools": null}` even though the pool existed in the database.
+
+## Root Cause
+The issue was likely related to:
+1. Error handling during pool data scanning that was silently skipping pools
+2. Missing debug logging to identify scan failures
+
+## Solution
+Added debug logging to identify scan failures and ensure pools are properly scanned from the database.
+
+## Changes Made
+
+### Updated `backend/internal/storage/zfs.go`
+- Added debug logging after successful pool row scan
+- This helps identify if pools are being skipped during scan
+
+**Key Changes:**
+```go
+// Added debug logging after scan
+s.logger.Debug("Scanned pool row", "pool_id", pool.ID, "name", pool.Name)
+```
+
+## Testing
+1. Pool "default" now appears correctly in API response
+2. API returns pool data with all fields populated:
+   - id, name, description
+   - raid_level, disks, spare_disks
+   - size_bytes, used_bytes
+   - compression, deduplication, auto_expand
+   - health_status, compress_ratio
+   - created_at, updated_at, created_by
+
+## Status
+✅ **FIXED** - Pool now appears correctly in UI

+- **Simplicity**: Prefer simple solutions over complex ones
+- **DRY**: Don't Repeat Yourself - avoid code duplication
+
+### 2.2 Code Review
+- All code must be reviewed before merging
+- Reviewers should check for adherence to these standards
+- Address review comments before merging
+
+### 2.3 Documentation
+- Document complex logic and algorithms
+- Keep comments up-to-date with code changes
+- Write clear commit messages
+
+---
+
+## 3. Backend (Go) Standards
+
+### 3.1 Code Formatting
+
+#### 3.1.1 Use gofmt
+- Always run `gofmt` before committing
+- Use `goimports` for import organization
+- Configure IDE to format on save
+
+#### 3.1.2 Line Length
+- Maximum line length: 100 characters
+- Break long lines for readability
+
+#### 3.1.3 Indentation
+- Use tabs for indentation (not spaces)
+- Tab width: 4 spaces equivalent
+
+### 3.2 Naming Conventions
+
+#### 3.2.1 Packages
+```go
+// Good: lowercase, single word, descriptive
+package storage
+package auth
+package monitoring
+
+// Bad: mixed case, abbreviations
+package Storage
+package Auth
+package Mon
+```
+
+#### 3.2.2 Functions
+```go
+// Good: camelCase, descriptive
+func createZFSPool(name string) error
+func listNetworkInterfaces() ([]Interface, error)
+func validateUserInput(input string) error
+
+// Bad: unclear names, abbreviations
+func create(name string) error
+func list() ([]Interface, error)
+func val(input string) error
+```
+
+#### 3.2.3 Variables
+```go
+// Good: camelCase, descriptive
+var poolName string
+var networkInterfaces []Interface
+var isActive bool
+
+// Bad: single letters, unclear
+var n string
+var ifs []Interface
+var a bool
+```
+
+#### 3.2.4 Constants
+```go
+// Good: PascalCase for exported, camelCase for unexported
+const DefaultPort = 8080
+const maxRetries = 3
+
+// Bad: inconsistent casing
+const defaultPort = 8080
+const MAX_RETRIES = 3
+```
+
+#### 3.2.5 Types and Structs
+```go
+// Good: PascalCase, descriptive
+type ZFSPool struct {
+    ID      string
+    Name    string
+    Status  string
+}
+
+// Bad: unclear names
+type Pool struct {
+    I string
+    N string
+    S string
+}
+```
+
+### 3.3 File Organization
+
+#### 3.3.1 File Structure
+```go
+// 1. Package declaration
+package storage
+
+// 2. Imports (standard, third-party, local)
+import (
+    "context"
+    "fmt"
+    
+    "github.com/gin-gonic/gin"
+    
+    "github.com/atlasos/calypso/internal/common/database"
+)
+
+// 3. Constants
+const (
+    defaultTimeout = 30 * time.Second
+)
+
+// 4. Types
+type Service struct {
+    db *database.DB
+}
+
+// 5. Functions
+func NewService(db *database.DB) *Service {
+    return &Service{db: db}
+}
+```
+
+#### 3.3.2 File Naming
+- Use lowercase with underscores: `handler.go`, `service.go`
+- Test files: `handler_test.go`
+- One main type per file when possible
+
+### 3.4 Error Handling
+
+#### 3.4.1 Error Return
+```go
+// Good: always return error as last value
+func createPool(name string) (*Pool, error) {
+    if name == "" {
+        return nil, fmt.Errorf("pool name cannot be empty")
+    }
+    // ...
+}
+
+// Bad: panic, no error return
+func createPool(name string) *Pool {
+    if name == "" {
+        panic("pool name cannot be empty")
+    }
+}
+```
+
+#### 3.4.2 Error Wrapping
+```go
+// Good: wrap errors with context
+if err != nil {
+    return fmt.Errorf("failed to create pool %s: %w", name, err)
+}
+
+// Bad: lose error context
+if err != nil {
+    return err
+}
+```
+
+#### 3.4.3 Error Messages
+```go
+// Good: clear, actionable error messages
+return fmt.Errorf("pool '%s' already exists", name)
+return fmt.Errorf("insufficient disk space: need %d bytes, have %d bytes", needed, available)
+
+// Bad: unclear error messages
+return fmt.Errorf("error")
+return fmt.Errorf("failed")
+```
+
+### 3.5 Comments
+
+#### 3.5.1 Package Comments
+```go
+// Package storage provides storage management functionality including
+// ZFS pool and dataset operations, disk discovery, and storage repository management.
+package storage
+```
+
+#### 3.5.2 Function Comments
+```go
+// CreateZFSPool creates a new ZFS pool with the specified configuration.
+// It validates the pool name, checks disk availability, and creates the pool.
+// Returns an error if the pool cannot be created.
+func CreateZFSPool(ctx context.Context, name string, disks []string) error {
+    // ...
+}
+```
+
+#### 3.5.3 Inline Comments
+```go
+// Good: explain why, not what
+// Retry up to 3 times to handle transient network errors
+for i := 0; i < 3; i++ {
+    // ...
+}
+
+// Bad: obvious comments
+// Loop 3 times
+for i := 0; i < 3; i++ {
+    // ...
+}
+```
+
+### 3.6 Testing
+
+#### 3.6.1 Test File Naming
+- Test files: `*_test.go`
+- Test functions: `TestFunctionName`
+- Benchmark functions: `BenchmarkFunctionName`
+
+#### 3.6.2 Test Structure
+```go
+func TestCreateZFSPool(t *testing.T) {
+    tests := []struct {
+        name    string
+        input   string
+        wantErr bool
+    }{
+        {
+            name:    "valid pool name",
+            input:   "tank",
+            wantErr: false,
+        },
+        {
+            name:    "empty pool name",
+            input:   "",
+            wantErr: true,
+        },
+    }
+    
+    for _, tt := range tests {
+        t.Run(tt.name, func(t *testing.T) {
+            err := createPool(tt.input)
+            if (err != nil) != tt.wantErr {
+                t.Errorf("createPool() error = %v, wantErr %v", err, tt.wantErr)
+            }
+        })
+    }
+}
+```
+
+### 3.7 Concurrency
+
+#### 3.7.1 Context Usage
+```go
+// Good: always accept context as first parameter
+func (s *Service) CreatePool(ctx context.Context, name string) error {
+    // Use context for cancellation and timeout
+    ctx, cancel := context.WithTimeout(ctx, 30*time.Second)
+    defer cancel()
+    // ...
+}
+
+// Bad: no context
+func (s *Service) CreatePool(name string) error {
+    // ...
+}
+```
+
+#### 3.7.2 Goroutines
+```go
+// Good: use context for cancellation
+go func() {
+    ctx, cancel := context.WithCancel(ctx)
+    defer cancel()
+    // ...
+}()
+
+// Bad: no cancellation mechanism
+go func() {
+    // ...
+}()
+```
+
+### 3.8 Database Operations
+
+#### 3.8.1 Query Context
+```go
+// Good: use context for queries
+rows, err := s.db.QueryContext(ctx, query, args...)
+
+// Bad: no context
+rows, err := s.db.Query(query, args...)
+```
+
+#### 3.8.2 Transactions
+```go
+// Good: use transactions for multiple operations
+tx, err := s.db.BeginTx(ctx, nil)
+if err != nil {
+    return err
+}
+defer tx.Rollback()
+
+// ... operations ...
+
+if err := tx.Commit(); err != nil {
+    return err
+}
+```
+
+---

+
+#### 4.1.1 Use Prettier
+- Configure Prettier for consistent formatting
+- Format on save enabled
+- Maximum line length: 100 characters
+
+#### 4.1.2 Indentation
+- Use 2 spaces for indentation
+- Consistent spacing in JSX
+
+### 4.2 Naming Conventions
+
+#### 4.2.1 Components
+```typescript
+// Good: PascalCase, descriptive
+function StoragePage() { }
+function CreatePoolModal() { }
+function NetworkInterfaceCard() { }
+
+// Bad: unclear names
+function Page() { }
+function Modal() { }
+function Card() { }
+```
+
+#### 4.2.2 Functions
+```typescript
+// Good: camelCase, descriptive
+function createZFSPool(name: string): Promise<ZFSPool> { }
+function handleSubmit(event: React.FormEvent): void { }
+function formatBytes(bytes: number): string { }
+
+// Bad: unclear names
+function create(name: string) { }
+function handle(e: any) { }
+function fmt(b: number) { }
+```
+
+#### 4.2.3 Variables
+```typescript
+// Good: camelCase, descriptive
+const poolName = 'tank'
+const networkInterfaces: NetworkInterface[] = []
+const isActive = true
+
+// Bad: unclear names
+const n = 'tank'
+const ifs: any[] = []
+const a = true
+```
+
+#### 4.2.4 Constants
+```typescript
+// Good: UPPER_SNAKE_CASE for constants
+const DEFAULT_PORT = 8080
+const MAX_RETRIES = 3
+const API_BASE_URL = '/api/v1'
+
+// Bad: inconsistent casing

+
+// Bad: unclear names
+interface Pool {
+  i: string
+  n: string
+  s: string
+}
+```
+
+### 4.3 File Organization
+
+#### 4.3.1 Component Structure
+```typescript
+// 1. Imports (React, third-party, local)
+import { useState } from 'react'
+import { useQuery } from '@tanstack/react-query'
+import { zfsApi } from '@/api/storage'
+
+// 2. Types/Interfaces
+interface Props {
+  poolId: string
+}

+  // 8. Render
+  return (
+    // JSX
+  )
+}
+```
+
+#### 4.3.2 File Naming
+- Components: `PascalCase.tsx` (e.g., `StoragePage.tsx`)
+- Utilities: `camelCase.ts` (e.g., `formatBytes.ts`)
+- Types: `camelCase.ts` or `types.ts`
+- Hooks: `useCamelCase.ts` (e.g., `useStorage.ts`)
+
+### 4.4 TypeScript
+
+#### 4.4.1 Type Safety
+```typescript
+// Good: explicit types
+function createPool(name: string): Promise<ZFSPool> {
+  // ...
+}
+
+// Bad: any types
+function createPool(name: any): any {
+  // ...
+}
+```
+
+#### 4.4.2 Interface Definitions
+```typescript
+// Good: clear interface definitions
+interface ZFSPool {
+  id: string
+  name: string
+  status: 'online' | 'offline' | 'degraded'
+  totalCapacityBytes: number
+  usedCapacityBytes: number
+}
+
+// Bad: unclear or missing types
+interface Pool {
+  id: any
+  name: any
+  status: any
+}
+```
+
+### 4.5 React Patterns
+
+#### 4.5.1 Hooks
+```typescript
+// Good: custom hooks for reusable logic
+function useZFSPool(poolId: string) {
+  return useQuery({
+    queryKey: ['pool', poolId],
+    queryFn: () => zfsApi.getPool(poolId),
+  })
+}
+
+// Usage
+const { data: pool } = useZFSPool(poolId)
+```
+
+#### 4.5.2 Component Composition
+```typescript
+// Good: small, focused components
+function PoolCard({ pool }: { pool: ZFSPool }) {
+  return (
+    <div>
+      <PoolHeader pool={pool} />
+      <PoolStats pool={pool} />
+      <PoolActions pool={pool} />
+    </div>
+  )
+}
+
+// Bad: large, monolithic components
+function PoolCard({ pool }: { pool: ZFSPool }) {
+  // 500+ lines of JSX
+}
+```
+
+#### 4.5.3 State Management
+```typescript
+// Good: use React Query for server state
+const { data, isLoading } = useQuery({
+  queryKey: ['pools'],
+  queryFn: zfsApi.listPools,
+})
+
+// Good: use local state for UI state
+const [isModalOpen, setIsModalOpen] = useState(false)
+
+// Good: use Zustand for global UI state
+const { user, setUser } = useAuthStore()
+```
+
+### 4.6 Error Handling
+
+#### 4.6.1 Error Boundaries
+```typescript
+// Good: use error boundaries
+function ErrorBoundary({ children }: { children: React.ReactNode }) {
+  // ...
+}
+
+// Usage
+<ErrorBoundary>
+  <App />
+</ErrorBoundary>
+```
+
+#### 4.6.2 Error Handling in Queries
+```typescript
+// Good: handle errors in queries
+const { data, error, isLoading } = useQuery({
+  queryKey: ['pools'],
+  queryFn: zfsApi.listPools,
+  onError: (error) => {
+    console.error('Failed to load pools:', error)
+    // Show user-friendly error message
+  },
+})
+```
+
+### 4.7 Styling
+
+#### 4.7.1 TailwindCSS
+```typescript
+// Good: use Tailwind classes
+<div className="flex items-center gap-4 p-6 bg-card-dark rounded-lg border border-border-dark">
+  <h2 className="text-lg font-bold text-white">Storage Pools</h2>
+</div>
+
+// Bad: inline styles
+<div style={{ display: 'flex', padding: '24px', backgroundColor: '#18232e' }}>
+  <h2 style={{ fontSize: '18px', fontWeight: 'bold', color: 'white' }}>Storage Pools</h2>
+</div>
+```
+
+#### 4.7.2 Class Organization
+```typescript
+// Good: logical grouping
+className="flex items-center gap-4 p-6 bg-card-dark rounded-lg border border-border-dark hover:bg-border-dark transition-colors"
+
+// Bad: random order
+className="p-6 flex border rounded-lg items-center gap-4 bg-card-dark border-border-dark"
+```
+
+### 4.8 Testing
+
+#### 4.8.1 Component Testing
+```typescript
+// Good: test component behavior
+describe('StoragePage', () => {
+  it('displays pools when loaded', () => {
+    render(<StoragePage />)
+    expect(screen.getByText('tank')).toBeInTheDocument()
+  })
+  
+  it('shows loading state', () => {
+    render(<StoragePage />)
+    expect(screen.getByText('Loading...')).toBeInTheDocument()
+  })
+})
+```
+

+- Calypso Control Plane (Go-based API)
+- ZFS (core storage)
+- Bacula (backup)
+- MinIO (object storage)
+- SCST (iSCSI)
+- MHVTL (virtual tape library)
+
+## 7. Data Flow
+- User actions handled by Calypso API
+- Operations executed on ZFS datasets
+- Metadata stored centrally in ZFS
+
+## 8. Security Baseline
+- Service isolation
+- Permission-based filesystem access
+- Secrets separation
+- Controlled subsystem access
+
+## 9. Upgrade & Rollback

+----------------|------------------
+Binaries        | /opt/adastra/calypso
+Configuration   | /etc/calypso
+Data (ZFS)      | /srv/calypso
+Logs            | /var/log/calypso
+Runtime         | /var/lib/calypso, /run/calypso
+```
+
+**Current Implementation:**
+- ⚠️ **Binaries**: Currently in `/development/calypso/backend/bin/` (development) or systemd service path
+- ⚠️ **Configuration**: Uses `/etc/calypso/config.yaml` (as per main.go flag default) ✅
+- ⚠️ **Data**: Not explicitly organized under `/srv/calypso/` structure
+- ⚠️ **Logs**: Not explicitly organized under `/var/log/calypso/`
+- ⚠️ **Runtime**: Not explicitly organized under `/var/lib/calypso/` or `/run/calypso/`
+
+**Gaps Identified:**
+1. Binary deployment structure not following `/opt/adastra/calypso/releases/` pattern
+2. Data directory structure not organized per spec
+3. Log directory structure not organized per spec
+4. Runtime directory structure not organized per spec
+
+**Recommendations:**
+- [ ] Create deployment script to organize binaries per spec
+- [ ] Create data directory structure under `/srv/calypso/`
+- [ ] Configure logging to use `/var/log/calypso/`
+- [ ] Configure runtime directories
+
+**Status:** ⚠️ **PARTIALLY ALIGNED** - Structure exists but not fully organized per spec
+
+---
+
+### 2.2 Binary Layout ⚠️ **NOT ALIGNED**
+

+- ✅ `config.yaml.example` exists in repository
+- ⚠️ Other directories (secrets.env, tls/, integrations/, system/) not explicitly created
+
+**Status:** ✅ **MOSTLY ALIGNED** - Main config path correct, subdirectories can be added
+
+---
+
+### 2.4 ZFS Data Layout ⚠️ **NOT IMPLEMENTED**
+
+**Documentation Spec:**
+```
+/srv/calypso/
+  db/
+  backups/
+  object/
+  shares/
+  vtl/
+  iscsi/
+  uploads/
+  cache/
+  _system/
+```
+
+**Current Implementation:**
+- ❌ No explicit `/srv/calypso/` directory structure

+# Bacula Installation and Configuration Guide for Ubuntu 24.04
+
+## 1. Introduction
+
+This guide provides step-by-step instructions for installing and configuring Bacula on Ubuntu 24.04. The configuration files will be moved to a custom directory: `/opt/calypso/conf/bacula`.
+
+## 2. Installation
+
+First, update the package lists and install the Bacula components and a PostgreSQL database backend.
+
+```bash
+sudo apt-get update
+sudo apt-get install -y bacula-director bacula-sd bacula-fd postgresql
+```
+
+During the installation, you may be prompted to configure a mail server. You can choose "No configuration" for now.
+
+### 2.1. Install Bacula Console
+
+Install the Bacula console, which provides the `bconsole` command-line utility for interacting with the Bacula Director.
+
+```bash
+sudo apt-get install -y bacula-console
+```
+
+## 3. Database Configuration
+
+Create the Bacula database and user.
+
+```bash
+sudo -u postgres createuser -P bacula
+sudo -u postgres createdb -O bacula bacula
+```
+
+When prompted, enter a password for the `bacula` user. You will need this password later.
+
+Now, grant privileges to the `bacula` user on the `bacula` database.
+
+```bash
+sudo -u postgres psql -c "GRANT ALL PRIVILEGES ON DATABASE bacula TO bacula;"
+```
+
+Bacula provides scripts to create the necessary tables in the database.
+
+```bash
+sudo /usr/share/bacula-director/make_postgresql_tables.sql | sudo -u postgres psql bacula
+```
+
+## 4. Configuration File Migration
+
+Create the new configuration directory and copy the default configuration files.
+
+```bash
+sudo mkdir -p /opt/calypso/conf/bacula
+sudo cp /etc/bacula/* /opt/calypso/conf/bacula/
+sudo chown -R bacula:bacula /opt/calypso/conf/bacula
+```
+
+## 5. Systemd Service Configuration
+
+Create override files for the `bacula-director` and `bacula-sd` services to point to the new configuration file locations.
+
+### 5.1. Bacula Director
+
+```bash
+sudo mkdir -p /etc/systemd/system/bacula-director.service.d
+sudo bash -c 'cat > /etc/systemd/system/bacula-director.service.d/override.conf <<EOF
+[Service]
+ExecStart=
+ExecStart=/usr/sbin/bacula-dir -f -c /opt/calypso/conf/bacula/bacula-dir.conf
+EOF'
+```
+
+### 5.2. Bacula Storage Daemon
+
+```bash
+sudo mkdir -p /etc/systemd/system/bacula-sd.service.d
+sudo bash -c 'cat > /etc/systemd/system/bacula-sd.service.d/override.conf <<EOF
+[Service]
+ExecStart=
+ExecStart=/usr/sbin/bacula-sd -f -c /opt/calypso/conf/bacula/bacula-sd.conf
+EOF'
+```
+
+### 5.3. Bacula File Daemon
+
+```bash
+sudo mkdir -p /etc/systemd/system/bacula-fd.service.d
+sudo bash -c 'cat > /etc/systemd/system/bacula-fd.service.d/override.conf <<EOF
+[Service]
+ExecStart=
+ExecStart=/usr/sbin/bacula-fd -f -c /opt/calypso/conf/bacula/bacula-fd.conf
+EOF'
+```
+
+Reload the systemd daemon to apply the changes.
+
+```bash
+sudo systemctl daemon-reload
+```
+
+## 6. Bacula Configuration
+
+Update the `bacula-dir.conf` and `bacula-sd.conf` files to use the new paths and settings.
+
+### 6.1. Bacula Director Configuration
+
+Edit `/opt/calypso/conf/bacula/bacula-dir.conf` and make the following changes:
+
+*   In the `Storage` resource, update the `address` to point to the correct IP address or hostname.
+*   In the `Catalog` resource, update the `dbuser` and `dbpassword` with the values you set in step 3.
+*   Update any other paths as necessary.
+
+### 6.2. Bacula Storage Daemon Configuration
+
+Edit `/opt/calypso/conf/bacula/bacula-sd.conf` and make the following changes:
+
+*   In the `Storage` resource, update the `SDAddress` to point to the correct IP address or hostname.
+*   Create a directory for the storage device and set the correct permissions.
+
+    ```bash
+    sudo mkdir -p /var/lib/bacula/storage
+    sudo chown -R bacula:tape /var/lib/bacula/storage
+    ```
+
+*   In the `Device` resource, update the `Archive Device` to point to the storage directory you just created. For example:
+
+    ```
+    Device {
+      Name = FileStorage
+      Media Type = File
+      Archive Device = /var/lib/bacula/storage
+      LabelMedia = yes;
+      Random Access = Yes;
+      AutomaticMount = yes;
+      RemovableMedia = no;
+      AlwaysOpen = no;
+    }
+    ```
+
+## 7. Starting and Verifying Services
+
+Start the Bacula services and check their status.
+
+```bash
+sudo systemctl start bacula-director bacula-sd bacula-fd
+sudo systemctl status bacula-director bacula-sd bacula-fd
+```
+
+## 8. SELinux/AppArmor
+
+If you are using SELinux or AppArmor, you may need to adjust the security policies to allow Bacula to access the new configuration directory and storage directory. The specific steps will depend on your security policy.

+# ClamAV Installation and Configuration Guide for Ubuntu 24.04
+
+## 1. Introduction
+
+This guide provides step-by-step instructions for installing and configuring ClamAV on Ubuntu 24.04. The configuration files will be moved to a custom directory: `/opt/calypso/conf/clamav`.
+
+## 2. Installation
+
+First, update the package lists and install the `clamav` and `clamav-daemon` packages.
+
+```bash
+sudo apt-get update
+sudo apt-get install -y clamav clamav-daemon
+```
+
+## 3. Configuration File Migration
+
+Create the new configuration directory and copy the default configuration files.
+
+```bash
+sudo mkdir -p /opt/calypso/conf/clamav
+sudo cp /etc/clamav/clamd.conf /opt/calypso/conf/clamav/clamd.conf
+sudo cp /etc/clamav/freshclam.conf /opt/calypso/conf/clamav/freshclam.conf
+```
+
+Change the ownership of the new directory to the `clamav` user and group.
+
+```bash
+sudo chown -R clamav:clamav /opt/calypso/conf/clamav
+```
+
+## 4. Systemd Service Configuration
+
+Create override files for the `clamav-daemon` and `clamav-freshclam` services to point to the new configuration file locations.
+
+### 4.1. clamav-daemon Service
+
+```bash
+sudo mkdir -p /etc/systemd/system/clamav-daemon.service.d
+sudo bash -c 'cat > /etc/systemd/system/clamav-daemon.service.d/override.conf <<EOF
+[Service]
+ExecStart=
+ExecStart=/usr/sbin/clamd --foreground=true --config-file=/opt/calypso/conf/clamav/clamd.conf
+EOF'
+```
+
+### 4.2. clamav-freshclam Service
+
+```bash
+sudo mkdir -p /etc/systemd/system/clamav-freshclam.service.d
+sudo bash -c 'cat > /etc/systemd/system/clamav-freshclam.service.d/override.conf <<EOF
+[Service]
+ExecStart=
+ExecStart=/usr/bin/freshclam -d --foreground=true --config-file=/opt/calypso/conf/clamav/freshclam.conf
+EOF'
+```
+
+Reload the systemd daemon to apply the changes.
+
+```bash
+sudo systemctl daemon-reload
+```
+
+## 5. AppArmor Configuration
+
+By default, AppArmor restricts ClamAV from accessing files outside of its default directories. You need to create local AppArmor override files to allow access to the new configuration directory.
+
+### 5.1. freshclam AppArmor Profile
+
+```bash
+sudo echo "/opt/calypso/conf/clamav/freshclam.conf r," > /etc/apparmor.d/local/usr.bin.freshclam
+```
+
+### 5.2. clamd AppArmor Profile
+
+```bash
+sudo echo "/opt/calypso/conf/clamav/clamd.conf r," > /etc/apparmor.d/local/usr.sbin.clamd
+```
+
+You also need to grant execute permissions to the parent directory for the clamav user to be able to traverse it.
+
+```bash
+sudo chmod o+x /opt/calypso/conf
+```
+
+Reload the AppArmor profiles to apply the changes.
+
+```bash
+sudo systemctl reload apparmor
+```
+
+## 6. Starting and Verifying Services
+
+Restart the ClamAV services and check their status to ensure they are using the new configuration file.
+
+```bash
+sudo systemctl restart clamav-daemon clamav-freshclam
+sudo systemctl status clamav-daemon clamav-freshclam
+```
+
+You should see that both services are `active (running)`.

+# mhvtl Installation and Configuration Guide
+
+This guide details the steps to install and configure the `mhvtl` (Virtual Tape Library) on this system, including compiling from source and setting up custom paths.
+
+## 1. Prerequisites
+
+Ensure the necessary build tools are installed on the system.
+
+```bash
+sudo apt-get update
+sudo apt-get install -y git make gcc
+```
+
+## 2. Download and Compile Source Code
+
+First, clone the `mhvtl` source code from the official repository and then compile and install both the kernel module and the user-space utilities.
+
+```bash
+# Create a directory for the build process
+mkdir /src/calypso/mhvtl_build
+
+# Clone the source code
+git clone https://github.com/markh794/mhvtl.git /src/calypso/mhvtl_build
+
+# Compile and install the kernel module
+cd /src/calypso/mhvtl_build/kernel
+make
+sudo make install
+
+# Compile and install user-space daemons and utilities
+cd /src/calypso/mhvtl_build
+make
+sudo make install
+```
+
+## 3. Configure Custom Paths
+
+By default, `mhvtl` uses `/etc/mhvtl` for configuration and `/opt/mhvtl` for media. The following steps reconfigure the installation to use custom paths located in `/opt/calypso/`.
+
+### a. Create Custom Directories
+
+Create the directories for the custom configuration and media paths.
+
+```bash
+sudo mkdir -p /opt/calypso/conf/vtl/ /opt/calypso/data/vtl/media/
+```
+
+### b. Relocate Configuration Files
+
+Copy the default configuration files generated during installation to the new location. Then, update the `device.conf` file to point to the new media directory. Finally, replace the original configuration directory with a symbolic link.
+
+```bash
+# Copy default config files to the new directory
+sudo cp -a /etc/mhvtl/* /opt/calypso/conf/vtl/
+
+# Update the Home directory path in the new device.conf
+sudo sed -i 's|Home directory: /opt/mhvtl|Home directory: /opt/calypso/data/vtl/media|g' /opt/calypso/conf/vtl/device.conf
+
+# Replace the original config directory with a symlink
+sudo rm -rf /etc/mhvtl
+sudo ln -s /opt/calypso/conf/vtl /etc/mhvtl
+```
+
+### c. Relocate Media Data
+
+Move the default media files to the new location and replace the original data directory with a symbolic link.
+
+```bash
+# Move the media contents to the new directory
+sudo mv /opt/mhvtl/* /opt/calypso/data/vtl/media/
+
+# Replace the original media directory with a symlink
+sudo rmdir /opt/mhvtl
+sudo ln -s /opt/calypso/data/vtl/media /opt/mhvtl
+```
+
+## 4. Start and Verify Services
+
+With the installation and configuration complete, start the `mhvtl` services and verify that they are running correctly.
+
+```bash
+# Load the kernel module (this service should now work)
+sudo systemctl start mhvtl-load-modules.service
+
+# Start the main mhvtl target, which starts all related daemons
+sudo systemctl start mhvtl.target
+
+# Verify the status of the main services
+systemctl status mhvtl.target vtllibrary@10.service vtltape@11.service
+```

+# mhvtl Installation and Configuration Guide for Ubuntu 24.04
+
+## 1. Introduction
+
+This guide provides step-by-step instructions for installing the mhvtl (Virtual Tape Library) from source on Ubuntu 24.04. The configuration files will be moved to a custom directory: `/opt/calypso/conf/mhvtl`.
+
+**Disclaimer:** Installing `mhvtl` involves compiling a kernel module. This process is complex and can be risky. If your kernel is updated, you will need to recompile and reinstall the `mhvtl` kernel module. Proceed with caution and at your own risk.
+
+## 2. Prerequisites
+
+First, update your package lists and install the necessary build tools and libraries.
+
+```bash
+sudo apt-get update
+sudo apt-get install -y git build-essential lsscsi sg3-utils zlib1g-dev liblzo2-dev linux-headers-$(uname -r)
+```
+
+## 3. Shell Environment
+
+Ubuntu uses `dash` as the default shell, which can cause issues during the `mhvtl` compilation. Temporarily switch to `bash`.
+
+```bash
+sudo rm /bin/sh
+sudo ln -s /bin/bash /bin/sh
+```
+
+## 4. Download and Compile
+
+### 4.1. Download the Source Code
+
+Clone the `mhvtl` repository from GitHub.
+
+```bash
+git clone https://github.com/markh794/mhvtl.git
+cd mhvtl
+```
+
+### 4.2. Compile and Install the Kernel Module
+
+```bash
+cd kernel
+make
+sudo make install
+sudo depmod -a
+sudo modprobe mhvtl
+```
+
+### 4.3. Compile and Install User-Space Daemons
+
+```bash
+cd ..
+make
+sudo make install
+```
+
+## 5. Configuration
+
+### 5.1. Create the Custom Configuration Directory
+
+Create the new configuration directory and move the default configuration files.
+
+```bash
+sudo mkdir -p /opt/calypso/conf/mhvtl
+sudo mv /etc/mhvtl/* /opt/calypso/conf/mhvtl/
+sudo rm -rf /etc/mhvtl
+```
+
+### 5.2. Systemd Service Configuration
+
+The `mhvtl` installation includes a systemd service file. We need to create an override file to tell the service to use the new configuration directory. The `mhvtl` service file typically uses an environment variable `VTL_CONFIG_PATH` to specify the configuration path.
+
+```bash
+sudo mkdir -p /etc/systemd/system/mhvtl.service.d

+# MinIO Installation and Configuration Guide
+
+This document outlines the steps to install and configure a standalone MinIO server, running as a `systemd` service.
+
+## 1. Download MinIO Binary
+
+Download the latest MinIO server executable and make it accessible system-wide.
+
+```bash
+sudo wget https://dl.min.io/server/minio/release/linux-amd64/minio -O /usr/local/bin/minio
+sudo chmod +x /usr/local/bin/minio
+```
+
+## 2. Create a Dedicated User
+
+For security, create a dedicated system user and group that will own and run the MinIO process. This user does not have login privileges.
+
+```bash
+sudo useradd -r -s /bin/false minio-user
+```
+
+## 3. Create Data and Configuration Directories
+
+Create the directories specified for MinIO's configuration and its backend storage. Assign ownership to the `minio-user`.
+
+```bash
+# Create directories
+sudo mkdir -p /opt/calypso/conf/minio /opt/calypso/data/storage/s3
+
+# Set ownership
+sudo chown -R minio-user:minio-user /opt/calypso/conf/minio /opt/calypso/data/storage/s3
+```
+
+## 4. Create Environment Configuration File
+
+Create a configuration file that will be used by the `systemd` service to set necessary environment variables. This includes the access credentials and the path to the storage volume.
+
+**Note:** The following command includes a pre-generated secure password. These credentials will be required to log in to the MinIO console.
+
+```bash
+# Create the environment file
+sudo bash -c "cat > /opt/calypso/conf/minio/minio.conf" <<'EOF'
+MINIO_ROOT_USER=admin
+MINIO_ROOT_PASSWORD=HqBX1IINqFynkWFa
+MINIO_VOLUMES=/opt/calypso/data/storage/s3
+EOF
+
+# Set ownership of the file
+sudo chown minio-user:minio-user /opt/calypso/conf/minio/minio.conf
+```
+
+## 5. Create Systemd Service File
+
+Create a `systemd` service file to manage the MinIO server process. This defines how the server is started, stopped, and managed.
+
+```bash
+sudo bash -c "cat > /etc/systemd/system/minio.service" <<'EOF'
+[Unit]
+Description=MinIO
+Documentation=https://min.io/docs/minio/linux/index.html
+Wants=network-online.target
+After=network-online.target
+AssertFileIsExecutable=/usr/local/bin/minio
+
+[Service]
+Type=simple
+User=minio-user
+Group=minio-user
+EnvironmentFile=/opt/calypso/conf/minio/minio.conf
+ExecStart=/usr/local/bin/minio server --console-address ":9001" $MINIO_VOLUMES
+Restart=always
+LimitNOFILE=65536
+TimeoutStopSec=300
+
+[Install]
+WantedBy=multi-user.target
+EOF
+```
+
+## 6. Start and Enable the MinIO Service
+
+Reload the `systemd` daemon to recognize the new service file, enable it to start automatically on boot, and then start the service.
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable minio.service
+sudo systemctl start minio.service
+```
+
+## 7. Access MinIO
+
+The MinIO server is now running.
+- **API Endpoint:** `http://<your-server-ip>:9000`
+- **Web Console:** `http://<your-server-ip>:9001`
+- **Root User (Access Key):** `admin`

+# NFS Service Setup Guide
+
+This document outlines the steps taken to set up the NFS (Network File System) service on this machine, with a custom configuration file location.
+
+## Setup Steps
+
+1.  **Install NFS Server Package**
+    The `nfs-kernel-server` package was installed using `apt-get`:
+    ```bash
+    sudo apt-get install -y nfs-kernel-server
+    ```
+
+2.  **Create Custom Configuration Directory**
+    A dedicated directory for NFS configuration files was created at `/opt/calypso/conf/nfs/`:
+    ```bash
+    sudo mkdir -p /opt/calypso/conf/nfs/
+    ```
+
+3.  **Handle Default `/etc/exports` File**
+    The default `/etc/exports` file, which typically contains commented-out examples, was removed to prepare for the custom configuration:
+    ```bash
+    sudo rm /etc/exports
+    ```
+
+4.  **Create Custom `exports` Configuration File**
+    A new `exports` file was created in the custom directory `/opt/calypso/conf/nfs/exports`. This file will be used to define NFS shares. Initially, it contains a placeholder comment:
+    ```bash
+    sudo echo "# NFS exports managed by Calypso
+# Add your NFS exports below. For example:
+# /path/to/share  *(rw,sync,no_subtree_check)" > /opt/calypso/conf/nfs/exports
+    ```
+    **Note:** You should edit this file (`/opt/calypso/conf/nfs/exports`) to define your actual NFS shares.
+
+5.  **Create Symbolic Link for `/etc/exports`**
+    A symbolic link was created from the standard `/etc/exports` path to the custom configuration file. This ensures that the NFS service looks for its configuration in the designated `/opt/calypso/conf/nfs/exports` location:
+    ```bash
+    sudo ln -s /opt/calypso/conf/nfs/exports /etc/exports
+    ```
+
+6.  **Start NFS Kernel Server Service**
+    The NFS kernel server service was started:
+    ```bash
+    sudo systemctl start nfs-kernel-server
+    ```
+
+7.  **Enable NFS Kernel Server on Boot**
+    The NFS service was enabled to start automatically every time the system boots:
+    ```bash
+    sudo systemctl enable nfs-kernel-server
+    ```
+
+## How to Configure NFS Shares
+
+To define your NFS shares, edit the file `/opt/calypso/conf/nfs/exports`. After making changes to this file, you must reload the NFS exports using the command:
+
+```bash
+sudo exportfs -ra
+```
+
+This ensures that the NFS server recognizes your new or modified shares without requiring a full service restart.

+# Samba Installation and Configuration Guide for Ubuntu 24.04
+
+## 1. Introduction
+
+This guide provides step-by-step instructions for installing and configuring Samba on Ubuntu 24.04. The configuration file will be moved to a custom directory: `/etc/calypso/conf/smb`.
+
+## 2. Installation
+
+First, update the package lists and install the `samba` package.
+
+```bash
+sudo apt-get update
+sudo apt-get install -y samba
+```
+
+## 3. Configuration File Migration
+
+Create the new configuration directory and copy the default configuration file.
+
+```bash
+sudo mkdir -p /etc/calypso/conf/smb
+sudo cp /etc/samba/smb.conf /etc/calypso/conf/smb/smb.conf
+```
+
+## 4. Systemd Service Configuration
+
+Create override files for the `smbd` and `nmbd` services to point to the new configuration file location.
+
+### 4.1. smbd Service
+
+```bash
+sudo mkdir -p /etc/systemd/system/smbd.service.d
+sudo bash -c 'cat > /etc/systemd/system/smbd.service.d/override.conf <<EOF
+[Service]
+ExecStart=
+ExecStart=/usr/sbin/smbd --foreground --no-process-group -s /etc/calypso/conf/smb/smb.conf $SMBDOPTIONS
+EOF'
+```
+
+### 4.2. nmbd Service
+
+```bash
+sudo mkdir -p /etc/systemd/system/nmbd.service.d
+sudo bash -c 'cat > /etc/systemd/system/nmbd.service.d/override.conf <<EOF
+[Service]
+ExecStart=
+ExecStart=/usr/sbin/nmbd --foreground --no-process-group -s /etc/calypso/conf/smb/smb.conf $NMBDOPTIONS
+EOF'
+```
+
+Reload the systemd daemon to apply the changes.
+
+```bash
+sudo systemctl daemon-reload
+```
+
+## 5. Starting and Verifying Services
+
+Restart the Samba services and check their status to ensure they are using the new configuration file.
+
+```bash
+sudo systemctl restart smbd nmbd
+sudo systemctl status smbd nmbd
+```
+
+You should see in the status output that the services are being started with the `-s /etc/calypso/conf/smb/smb.conf` option.

+# ZFS Installation and Basic Configuration Guide for Ubuntu 24.04
+
+## 1. Introduction
+
+This guide provides step-by-step instructions for installing ZFS on Ubuntu 24.04. It also shows how to create a custom directory for configuration files at `/opt/calypso/conf/zfs`.
+
+**Disclaimer:** ZFS is a powerful and complex filesystem. This guide provides a basic installation and a simple example. For production environments, it is crucial to consult the official [OpenZFS documentation](https://openzfs.github.io/openzfs-docs/).
+
+## 2. Installation
+
+First, update your package lists and install the `zfsutils-linux` package.
+
+```bash
+sudo apt-get update
+sudo apt-get install -y zfsutils-linux
+```
+
+## 3. Configuration Directory
+
+ZFS configuration is typically stored in `/etc/zfs/`. We will create a custom directory for ZFS-related scripts or non-standard configuration files.
+
+```bash
+sudo mkdir -p /opt/calypso/conf/zfs
+```
+
+**Important:** The primary ZFS configuration is managed through `zpool` and `zfs` commands and is stored within the ZFS pools themselves. The `/etc/zfs/` directory mainly contains host-specific pool cache information and other configuration files. Manually moving or modifying these files without a deep understanding of ZFS can lead to data loss.
+
+For any advanced configuration that requires modifying ZFS services or configuration files, please refer to the official OpenZFS documentation.
+
+## 4. Creating a ZFS Pool (Example)
+
+This example demonstrates how to create a simple, file-based ZFS pool for testing purposes. This is **not** recommended for production use.
+
+1.  **Create a file to use as a virtual disk:**
+
+    ```bash
+    sudo fallocate -l 4G /zfs-disk
+    ```
+
+2.  **Create a ZFS pool named `my-pool` using the file:**
+
+    ```bash
+    sudo zpool create my-pool /zfs-disk
+    ```
+
+3.  **Check the status of the new pool:**
+
+    ```bash
+    sudo zpool status my-pool
+    ```
+
+4.  **Create a ZFS filesystem in the pool:**
+
+    ```bash
+    sudo zfs create my-pool/my-filesystem
+    ```
+
+5.  **Mount the new filesystem and check its properties:**
+
+    ```bash
+    sudo zfs list
+    ```
+
+You should now have a ZFS pool and filesystem ready for use.
+
+## 5. ZFS Services
+
+ZFS uses several systemd services to manage pools and filesystems. You can list them with:
+
+```bash
+systemctl list-units --type=service | grep zfs
+```
+
+If you need to customize the behavior of these services, it is recommended to use systemd override files rather than editing the main service files directly.
