+# 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.
+
+## Changes Made
+
+### Updated `backend/internal/storage/zfs.go`
+**File**: `backend/internal/storage/zfs.go` (line 425-442)
+
+**Before:**
+```go
+var pool ZFSPool
+var description sql.NullString
+err := rows.Scan(
+    &pool.ID, &pool.Name, &description, &pool.RaidLevel, pq.Array(&pool.Disks),
+    &pool.SizeBytes, &pool.UsedBytes, &pool.Compression, &pool.Deduplication,
+    &pool.AutoExpand, &pool.ScrubInterval, &pool.IsActive, &pool.HealthStatus,
+    &pool.CreatedAt, &pool.UpdatedAt, &pool.CreatedBy, // Direct scan to string
+)
+```
+
+**After:**
+```go
+var pool ZFSPool
+var description sql.NullString
+var createdBy sql.NullString
+err := rows.Scan(
+    &pool.ID, &pool.Name, &description, &pool.RaidLevel, pq.Array(&pool.Disks),
+    &pool.SizeBytes, &pool.UsedBytes, &pool.Compression, &pool.Deduplication,
+    &pool.AutoExpand, &pool.ScrubInterval, &pool.IsActive, &pool.HealthStatus,
+    &pool.CreatedAt, &pool.UpdatedAt, &createdBy, // Scan to NullString
+)
+if err != nil {
+    s.logger.Error("Failed to scan pool row", "error", err, "error_type", fmt.Sprintf("%T", err))
+    continue
+}
+if createdBy.Valid {
+    pool.CreatedBy = createdBy.String
+}
+```
+
+## Testing
+1. Pool ada di database: `default-pool`
+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
+
+## Next Steps
+- Refresh browser untuk melihat perubahan
+- Klik tombol "Refresh Pools" untuk manual refresh
+- Pool seharusnya muncul di UI sekarang
