Scrubbing List — /opt/stacks (2026-05-17)

Read-only audit of unused/stale data. Nothing here has been deleted — review the labels and run the commands yourself. Root FS was 165G/200G used (83%); /var/lib/docker is 86G of /opt/stacks's 99G.

No stopped/exited/*_old containers; no unused custom networks (already clean).

1. Docker reclaimable

Target Size Label Command
Build cache (268 entries, old comfyui CPU→Arc rebuilds, 0 in use) ~20.85 GB SAFE docker builder prune -af
4× dangling <none> mcp-gateway rebuild images (1.59 GB ea) ~6.36 GB SAFE docker image prune
2 old dangling images (756 MB + 113 MB) ~0.87 GB SAFE (same docker image prune)
~265 anon volumes; one 54bcf7… = 8.69 GB unidentified, rest ~0B ~9 GB REVIEW inspect 54bcf7… then docker volume prune
Named dangling vols: n8n_n8n_storage 128M, ai_mcpo-data 84M, paperless-ngx_pgdata 26M, metamcp_postgres_data 18M, daytona*_db_data 15M×2, librechat_pgdata2 13M, arcane_arcane-data 12M, ai_redis_data 7.6M ~0.3 GB REVIEW docker volume rm <name> per-item after confirming the stack is retired

In-use, DO NOT REMOVE: comfyui-comfyui (6.45G), clusterzx/paperless-ai (8.59G).

2. Migrated/abandoned local data dirs (compose now points to UNAS)

Path Size Label Note
arr-stack/media 55 G REVIEW No container mounts it; arr → /mnt/pve/unas/media. Audiobooks/ebooks have recent mtimes (rsync residue) — parity-check vs UNAS before rm -rf
ai/data (old postgres) 195 M SAFE Not mounted, not referenced
ai/postgres_data (incl 38M pg_wal) 120 M REVIEW Not mounted/referenced but recent mtime
ai/meili_data_v1.35.1 19 M SAFE Old Meili, not mounted
qdrant/qdrant_storage 7 M SAFE qdrant migrated to UNAS (fresh start)
daytona/db_data 14 M REVIEW No mount; daytona uses named volumes
n8n/data empty SAFE rmdir

Active local, KEEP: immich/postgres (814M), ai/lobehub/data (25M), shared-db/wal-g (27M, RO mount), arr-stack configs, ai/litellm-config, ai/searxng.

3. Migration / scratch artifacts

Path Label Note
ai/docker (0 B), ai/bucket.config.json (empty dir) SAFE junk
scripts/traefik-*.sh SAFE Traefik abandoned for Zoraxy
scripts/{migrate_*,test_adguard_api,zoraxy_csrf,zoraxy_test,configure_zoraxy_*}.py REVIEW one-shot done; confirm no rerun need
scripts/zoraxy_sync.py KEEP ongoing proxy tooling
scripts/.venv (29M), scripts/.kilo (30M) REVIEW regenerable caches
/tmp/{flux_*,pw_ui,add_*,fix_*}.* , /tmp/*.png , /tmp/*.log SAFE ~1.8M scratch (this session)

Bottom line

  • Safe-only reclaim: ~2930 GB (build cache + dangling images dominate).
  • With review: +~64 GB (55G stale arr-stack/media after UNAS parity check, ~9G anon vols).
  • Highest-value, zero-risk action: docker builder prune -af → ~20.85 GB now.
  • Biggest overall prize: verify+remove arr-stack/media (55 G) — parity-check vs /mnt/pve/unas/media first.
