# 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
