Check disk space

The NAS pool holds media, photos, torrents, and Docker app data. Running out of space stops imports, breaks uploads, and can crash apps. Check space in TrueNAS before large downloads or photo syncs.

Quick check (dashboard)

  1. Open dsm.saxobroko.com or https://192.168.2.203 on the home network.
  2. Log in with TrueNAS admin credentials (Vaultwarden).
  3. On the main dashboard, find the Storage or Pool widget.
  4. Note:
  5. Total capacity
  6. Used vs Available
  7. Pool status — should be ONLINE (not DEGRADED)

If available space is under 10%, treat it as urgent — pause torrents and large uploads until you free space or add capacity.

Detailed check (Storage menu)

  1. In the TrueNAS UI, go to Storage (left sidebar).
  2. Click the main pool name (RAIDZ1 pool on the Ugreen DXP 8800 Plus).
  3. Review the Capacity bar at the top of the pool view.
  4. Scroll to Datasets — each row shows used space per dataset (media, photos, app volumes, etc.).
  5. Click a dataset name to see Used / Available for that folder only.

Useful datasets to watch:

Dataset use Why it matters
Media (Shows/Movies) Grows with Sonarr/Radarr and qBittorrent
Photos Immich thumbnails and uploads spike usage — Photos
App Docker volumes Config and download queues for *arr apps

Check from Windows (mapped drive)

If A: (media share) is mapped on the PC:

  1. Open File Explorer → This PC → A:
  2. Right-click the drive → Properties.
  3. Compare Used space and Free space.

This shows the share view, not the whole pool (system snapshots and other datasets may not appear). Use TrueNAS Storage for the authoritative number.

What to do when space is low

  1. Pause qBittorrent — stop new downloads completing to the pool.
  2. Check incomplete downloads — old partial files in the torrent folder.
  3. Review Sonarr/Radarr — delete wanted items you no longer need, or move completed media you are willing to remove (only if you understand re-download cost).
  4. Photos — large phone backup still running? Wait or move to Wi‑Fi-only sync.
  5. Do not delete ZFS snapshots unless you know what they are — see Backups and pool health.

Do not delete the pool or datasets to free space

Removing a dataset destroys everything inside it permanently. Free space by removing files you no longer need, not by deleting storage containers in TrueNAS.

When to worry

Sign Action
Pool DEGRADED When the pool is degraded — not a space issue
Apps crash with "no space" Free space immediately; restart affected apps — Restart a Docker app
Used space climbing fast with no downloads Check for runaway logs or duplicate imports in *arr apps
