# 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: ~29–30 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.
