Migration: TrueNAS to Ubuntu + Coolify

Motivation

TrueNAS is storage-first OS; not ideal for general-purpose app hosting and experimentation
Server idles 99% of the time — underutilized capacity
Coolify provides one-click app installs and git-push deploys (useful as a Laravel developer)
Current setup makes experimenting with new apps slow (e.g., OpenClaw took 3-4 hours)

Current Setup

OS: TrueNAS Scale (Debian-based) on NVMe SSD (nvme0n1)
Storage: ZFS stripe pool tank on two separate disks (~29T total, ~14.8T used)
Services: Traefik, Gitea, Servarr stack (Gluetun/ProtonVPN, qBittorrent, Sonarr, Radarr, Lidarr, Prowlarr, Bazarr, Recyclarr), CrowdSec, Dozzle, Watchtower
Paths: Stacks at /mnt/tank/stacks/, configs at /mnt/tank/configs/, media at /mnt/tank/media/

Target Setup

OS: Ubuntu Server on NVMe SSD
Storage: Same ZFS stripe pool tank, imported as-is
Management: Coolify for app deployment and management
Services: Same as before, plus easy deployment of new apps and Laravel projects

Migration Plan

Before Wiping TrueNAS

Document network config — static IP, DNS settings, hostname, router port forwards
Back up compose files and configs — copy /mnt/tank/stacks/ and /mnt/tank/configs/ to USB stick or laptop (they're on the ZFS pool and will survive, but be safe)
Export the ZFS pool cleanly:
```
zpool export tank
```
Note disk identifiers for the pool (already known from zpool status)

Install Ubuntu

Install Ubuntu Server on the NVMe SSD (wipes TrueNAS)
Set up networking — replicate static IP, hostname, DNS

Restore Storage

Install ZFS support:
```
sudo apt install zfsutils-linux
```
Import the pool at the same mount point:
```
sudo zpool import -d /dev/disk/by-id tank
```
Pool should appear at /tank — if paths need to match old config, set the mountpoint:
```
sudo zfs set mountpoint=/mnt/tank tank
```
Verify data integrity:
```
zpool status tank
zpool scrub tank
```

Install Coolify

Install Coolify (one-liner from their docs)
Decide on reverse proxy strategy:
- Option A: Use Coolify's built-in Traefik — simplest, let Coolify manage SSL and routing
- Option B: Keep existing Traefik + CrowdSec config — more control, but manage it outside Coolify
- Do NOT run both on port 443 simultaneously
Re-deploy services via Coolify using existing Docker Compose files from /mnt/tank/stacks/

Post-Migration

Verify Servarr stack — confirm VPN routing through Gluetun works
Verify Gitea — confirm repos are accessible
Set up disk monitoring:
```
sudo apt install smartmontools
```
Set up ZFS scrub cron (Ubuntu may set this up automatically, verify)
Test deploying a Laravel project via git push to confirm Coolify workflow

Gotchas

Mount point must match — Docker Compose files reference /mnt/tank/... paths
Coolify has its own Traefik — conflicts with existing Traefik if both claim port 443
ZFS pool must be exported cleanly before wiping TrueNAS, otherwise force-import is needed
Servarr stack VPN routing through Gluetun may need network config adjustments in Coolify's Docker environment
