- Add RESUME.md for cross-session continuity (open items, key state, constraints) - claude-max-bridge: implement /v1/responses (OpenAI Responses API) with previous_response_id chaining via server-side history injection into system prompt. Root cause of "session already in use": CLI leaves JSONL in un-resumable "dequeued" state after each --print run; fix avoids session reuse entirely. Also fixed: assistant content must be array-of-blocks not plain string (silent JS crash otherwise). - LiteLLM: add pass_through_endpoints for /v1/responses → claude-max-bridge - Storage, volumes, architecture docs reconciled (Vaultwarden → local zfs, Pocket-ID backup, WAL-G fix, apps/ decommission, Nextcloud CIFS→NFS) - Add ideas/, proxmox-memory-audit.md, llm-benchmark.md (new docs this session) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# Storage layout
|
|
|
|
> Verified state as of 2026-05-21. Source of truth for which service lives on which storage class.
|
|
> Earlier revisions of this doc were stale on multiple items (Garage, n8n, Arcane, Karakeep, Pocket-ID, arr-stack, Nextcloud's storage protocol, missing Coder/Gitea). Reconciled via live audit.
|
|
|
|
## Storage classes
|
|
|
|
| Class | Substrate | Where | Typical use |
|
|
|---|---|---|---|
|
|
| Local zfs (rootfs) | NVMe in nuc | `/opt/stacks/<stack>/` on each LXC | Tier-1 hot state: databases, SQLite, secret stores, anything latency-sensitive |
|
|
| Local zfs (subvol) | NVMe in nuc | `rpool/data/subvol-<NNN>-disk-0` per LXC | Container rootfs, image cache |
|
|
| Docker named volume | NVMe in nuc | `/var/lib/docker/volumes/...` on each Docker CT | Per-container persistent state managed by Docker |
|
|
| UNAS over **NFSv3** | `192.168.1.31` | `/mnt/pve/unas` on CTs 101, 103, 104, 105, 111 | Bulk media, workspace home dirs, document storage |
|
|
|
|
## What lives where (verified 2026-05-21)
|
|
|
|
### UNAS NFS — `/mnt/pve/unas/services/...`
|
|
|
|
Bulk + media + non-latency-sensitive app data.
|
|
|
|
| Service | CT | Path on UNAS → in container | Backed up? | Notes |
|
|
|---|---|---|---|---|
|
|
| Immich (uploads, thumbs, derived) | 104 | `services/immich/{encoded-video,profile,thumbs}` + `media/images` + `backup/immich` | Immich own pg_dump → `media/images/db-dumps`; no off-host copy | |
|
|
| Paperless-ngx (documents) | 104 | `media/documents/public/paperless-ngx/{consume,export,library}` | none | |
|
|
| Paperless-AI | 104 | `services/paperless-ai` → `/app/data` | none | |
|
|
| Traccar (logs, config) | 104 | `services/traccar/{logs,traccar.xml}` | none | data dir reverted to local `/opt/stacks/traccar/data` |
|
|
| Memos | 104 | `services/memos` → `/var/opt/memos` | none | |
|
|
| Arr-stack (Audiobookshelf, Prowlarr, RDTClient, Shelfarr) + media | 104 | `services/arr-stack/*` + `media/{audiobooks,ebooks,podcasts,Torrents}` | none | already migrated (older doc claimed "still local") |
|
|
| Gluetun (VPN) | 104 | `services/gluetun/data` → `/gluetun` | none | |
|
|
| Gitea | 111 | `services/gitea` → `/data` | none | new 2026-05-20 |
|
|
| Coder workspace home dirs | 111 | `services/coder/<user>/<workspace>` → `/home/<user>` | none | new 2026-05-20 |
|
|
| Backrest's jottacloud-mirrored data | 103 | `media/data-dir` only | **rclone → jottacloud (Backrest)** | only path with off-host backup |
|
|
|
|
### Local zfs — `/opt/stacks/...`
|
|
|
|
Tier-1 state and anything that should NOT be NFS-backed.
|
|
|
|
| Service | CT | Local path → in container | Backed up? | Notes |
|
|
|---|---|---|---|---|
|
|
| Pocket-ID | **110** | `/opt/stacks/pocketid/data` → `/app/data` | none | CT 110 has no NFS mount at all. Earlier doc said UNAS — incorrect. |
|
|
| Garage (S3 meta + data) | 104 | `/opt/stacks/shared-db/garage/{data,meta}` → `/var/lib/garage/*` | none | **moved off NFS** 2026-05-19 after WAL-G outage. Stale copy may still exist on UNAS. |
|
|
| Shared Postgres (multi-stack) | 104 | docker named volume `shared-db_shared-pgdata` | **WAL-G → local Garage** (configured; outage 2026-05-19 prompted move) | Garage itself is single-disk local — no off-host copy. |
|
|
| n8n | 104 | `/opt/stacks/n8n/data` → `/home/node/.n8n` | none | **back to local** after PG migration attempt failed. Stale 408 MB `database.sqlite` left on UNAS (May 15) — clean up. n8n now uses `shared-postgres` as its actual DB. |
|
|
| Arcane | 104 | `/opt/stacks/arcane/data` → `/app/data` | none | reverted from UNAS to local 2026-05-19 (undocumented before now) |
|
|
| Karakeep + Meilisearch | 104 | `/opt/stacks/karakeep/localdata/{data,meili}` | none | reverted from UNAS to local |
|
|
| Immich Postgres (pgvector) | 104 | `/opt/stacks/immich/postgres` → `/var/lib/postgresql/data` | Immich pg_dump → UNAS | tier-1; PG demands local disk |
|
|
| Homepage | 104 | `/opt/stacks/homepage/{config,icons}` | none | |
|
|
| Dozzle | 104 | `/opt/stacks/dozzle/dozzle_data` | none | |
|
|
| LiteLLM config | 104 | `/opt/stacks/ai/litellm-config` | none | |
|
|
| SearXNG config | 104 | `/opt/stacks/ai/searxng` | none | |
|
|
| Flaresolverr | 104 | `/var/lib/flaresolver` | none | |
|
|
| AdGuard / Zoraxy / DNS / Shepard / Backrest binaries | 102/108/103/101 | local zfs only | none | Backrest itself has no self-backup |
|
|
| Vaultwarden (attachments + key material) | 104 | `/opt/stacks/vaultwarden/data` → `/data` | none | **moved off NFS 2026-05-22**; DB is on CT 113 postgres; stale `db.sqlite3` deleted |
|
|
| Nextcloud config + sidecars | 105 | local zfs (CT rootfs) | none | app data on NFS — see below |
|
|
|
|
### Garage S3 buckets (on local zfs, CT 104)
|
|
|
|
| Bucket | Access key | Use | Public URL |
|
|
|---|---|---|---|
|
|
| `lobe-files` | GK55210… (from `.env`) | LobeHub file uploads + WAL-G PG backups | internal only |
|
|
| `chat-artifacts` | GK50bfc… | AI chat output artefacts (images, reports, SVG) | `https://chat-artifacts.s3.nuclide.systems/<key>` |
|
|
|
|
### Docker named volumes
|
|
|
|
Local on `/var/lib/docker/volumes/`. Mostly databases and caches.
|
|
|
|
| Volume | Service / CT | Backed up? |
|
|
|---|---|---|
|
|
| `shared-db_shared-pgdata` | shared-postgres / 104 | WAL-G → local Garage |
|
|
| `paperless-ngx_pgdata`, `_redisdata`, `_data` | paperless-ngx / 104 | none |
|
|
| `lobe-postgres` + `lobe-redis` | lobehub / 104 | none |
|
|
| `nuc-ai-core_rustfs-data` | lobehub stack / 104 | none |
|
|
| `pgadmin-data` | pgadmin / 104 | none (regenerable) |
|
|
| `immich_model-cache` | immich-ml / 104 | regenerable |
|
|
| `coder-db` + `gitea-db` (docker volume `coder-db`) | / 111 | none |
|
|
| (orphaned) `daytona-minimal_db_data` + runner anon vol | / 104 | none — clean up post-decommission |
|
|
|
|
### Nextcloud (CT 105) — data on NFS
|
|
|
|
Nextcloud AIO mounts `/mnt/pve/unas/services/nextcloud` via NFSv3 (same share as all other CTs). Migrated from CIFS on 2026-05-22 after the CIFS mount caused a crash-loop. The Postgres + Redis sidecars stay on local docker volumes.
|
|
|
|
## Backup reality
|
|
|
|
**There is effectively no off-host backup of service data.** The only configured Backrest plan covers `/mnt/pve/unas/media/data-dir → jottacloud` — i.e., Backrest backs up *one specific UNAS path*, not the services that write to UNAS.
|
|
|
|
Coverage:
|
|
|
|
- Immich pg_dump → UNAS (same filer; survives container loss, not filer loss)
|
|
- shared-postgres WAL-G → Garage (same host; survives container loss, not disk loss)
|
|
- Everything else: zero
|
|
|
|
This is a known gap. Plans:
|
|
1. Extend Backrest plans to snapshot tier-1 paths (Pocket-ID sqlite, Vaultwarden data, Gitea repos, Coder workspace homes) to jottacloud nightly.
|
|
2. Once the second NVMe lands (see `infra/proxmox-state.md` §6), mirror `rpool` so a single disk death doesn't take everything.
|

## Drift cleanup TODO
|
|
|
|
- [x] ~~Remove stale `services/n8n/database.sqlite` from UNAS~~ — gone (verified 2026-05-22)
|
|
- [x] ~~Remove stale `services/shared-db/garage/` copy from UNAS~~ — gone (verified 2026-05-22)
|
|
- [x] ~~Remove orphaned `daytona-minimal_db_data` Docker volume on CT 104~~ — gone (verified 2026-05-22)
|
|
- [x] ~~Vaultwarden `data/` on UNAS~~ — migrated to local zfs 2026-05-22. Stale NFS copy at `services/vaultwarden/` can be cleaned up.
|
|
- [x] ~~Add a Backrest plan for Pocket-ID DB~~ — done 2026-05-22. Pre-backup hook runs `pocket-id export` + copies keys to UNAS staging; `services-backup-plan` snapshots staging → jottacloud nightly.
