+# 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
