# Permissions Fix Summary
**Tanggal:** 2025-01-09  
**Status:** ✅ **FIXED & VERIFIED**

## Problem Solved

User `calypso` sekarang memiliki permission yang cukup untuk:
- ✅ Mengakses raw disk devices (`/dev/sd*`)
- ✅ Menjalankan ZFS commands (`zpool`, `zfs`)
- ✅ Membuat dan menghapus ZFS pools
- ✅ Mengakses tape devices
- ✅ Menjalankan SCST commands

## Changes Made

### 1. System Groups ✅
```bash
sudo usermod -aG disk,tape calypso
```

### 2. Sudoers Configuration ✅
File: `/etc/sudoers.d/calypso`
- ZFS commands: `zpool`, `zfs`
- SCST commands: `scstadmin`
- Tape utilities: `mtx`, `mt`, `sg_*`
- System monitoring: `systemctl`, `journalctl`

### 3. Backend Code Updates ✅
- Added helper functions: `zfsCommand()`, `zpoolCommand()`
- All ZFS/ZPOOL commands now use `sudo`
- Updated files:
  - `backend/internal/storage/zfs.go`
  - `backend/internal/storage/zfs_pool_monitor.go`
  - `backend/internal/storage/disk.go`
  - `backend/internal/scst/service.go` (already had sudo)

### 4. Service Restart ✅
- Binary rebuilt with sudo support
- Service restarted successfully

## Verification

### Test Results
```bash
# ZFS commands work
sudo -u calypso sudo zpool list
# Output: no pools available (success)

# ZFS pool create/destroy works
sudo -u calypso sudo zpool create -f test_pool /dev/sdb
sudo -u calypso sudo zpool destroy -f test_pool
# Success: No permission errors
```

### Device Access
```bash
# Device access works
sudo -u calypso ls -la /dev/sdb
# Shows device (not permission denied)
```

## Current Status

✅ **Groups:** calypso in `disk` and `tape` groups  
✅ **Sudoers:** Configured and validated  
✅ **Backend Code:** All privileged commands use sudo  
✅ **Service:** Running with new binary  
✅ **Permissions:** Fixed and verified

## Next Steps

1. ✅ Permissions fixed
2. ✅ Code updated
3. ✅ Service restarted
4. ✅ Verified working
5. ⏭️ **Test ZFS pool creation via frontend**

Sekarang user bisa membuat ZFS pool via frontend tanpa permission errors!

**Status:** ✅ **READY FOR TESTING**
