# truenas

**Role:** NAS — ZFS storage, NFS shares, S3 via [[rustfs]]
**IP:** 192.168.50.12
**Hostname:** TrueNAS
**Running on:** Proxmox VM 9001 (22.9 GB RAM, 32 GB boot disk, **running**)
**Web UI:** TrueNAS web interface (via browser)

## Overview

TrueNAS provides network storage for the homelab. It serves NFS shares to proxmox and the cluster nodes, and runs [[rustfs]] for S3-compatible object storage. It runs as VM 9001 on [[proxmox]].

## ⚠️ Pool Corruption

**Status:** Pool has known corruption issues. Monitor pool health via TrueNAS web UI.

Monitor for:
- Pool import failures on boot
- Checksum errors on disk
- NFS share timeouts

If the pool becomes unavailable, data on `SHGS31` (47% full, ~460 GB used) and `backups` (31% full, ~4.2 TB used) is at risk.

See [[nfs-storage]] skill for ZFS troubleshooting.

## SSH Access

⚠️ SSH access as `bear` user is **blocked** (Permission denied, publickey). The `bear` user's SSH key is not authorized on TrueNAS.

Options:
- Use the TrueNAS web UI for management
- Add `bear`'s SSH key to TrueNAS via the web UI
- Use `admin` or `root` account if keys are configured

## ZFS Pools

| Pool | Purpose | % Used | Notes |
|------|---------|--------|-------|
| `SHGS31` | General storage | 47% (~460 GB) | Main data pool |
| `backups` | Backup storage | 31% (~4.2 TB) | Large backup volume |
| `CT1000` | (unknown) | 3% | Smaller pool |

TrueNAS runs with these pools visible in the web UI under Storage.

## Shares

Known NFS exports:
- `/mnt/TrueNAS/traefik-certs/grizzley` — mounted by [[grizzley]] at `/mnt/truenas/traefik-certs/grizzley` (nfs4, rw)

Other shares to confirm via TrueNAS web UI:
- `/mnt/TrueNAS/` — main pool mount point
- May serve to: proxmox, ubuntu, ice

## rustfs (S3)

[[rustfs]] runs on TrueNAS via Docker (on TrueNAS itself or via bind mount) or on [[ubuntu]] as a Docker container connecting to TrueNAS storage.

**Current config on ubuntu:** rustfs Docker container on ubuntu binds to TrueNAS storage path for S3 bucket `obsidian-vault`:
- Endpoint: `http://192.168.50.12:9000`
- Access Key: `rustfsadmin`
- Secret Key: (stored in env or .env file)
- Bucket: `obsidian-vault`

On first boot, rustfs ignores env vars `RUSTFS_S3_ACCESS_KEY` and `RUSTFS_S3_SECRET_KEY` — uses hardcoded defaults (`rustfsadmin/rustfsadmin`). To reset: stop container, wipe data dir, restart.

## Access

```bash
# ⚠️ bear user SSH fails — use web UI or fix SSH keys
ssh admin@192.168.50.12  # may not work
ssh root@192.168.50.12   # may not work
# Best: use TrueNAS web UI
```
