Migration checklist 0%

Prepbackups · install media

Pi rescue tarballs safe off-device — secrets + databases good, agents tarball corrupt

Physically disconnect the 1TB HDD before touching the installer

Ubuntu Server 24.04 LTS downloaded + flashed (triple-check the target device)

InstallNVMe only

Boot the USB (F10 menu), Ubuntu Server minimized

Target the 256GB NVMe only, confirm by size

LVM trap — expand root or untick LVM (don't leave half the disk unallocated)

OpenSSH on, import from GitHub kay2stack, hostname kay2nuc

Baseupdates · tailscale · no sleep

full-upgrade + git/curl/htop/build-essential

tailscale up --ssh, confirm reachable from phone before going headless

Mask sleep/suspend targets, DHCP reservation set

Runtimenode · pm2 · cloudflared

Node 22 + PM2, pm2 startup line run

cloudflared + a new tunnel (don't reuse Pi creds)

Model + brainollama · STAN proxy

Ollama + qwen3:4b pulled, API smoke-tested on :11434

stan-proxy running under PM2, endpoint + token pasted into ⚙ above

Fleetclive · hermes · cutover

1TB HDD reconnected, mounted read-only first

Repos cloned fresh, fresh npm install per project (never copy ARM node_modules)

Secrets + DBs restored, PM2 bring-up: Eye → Clive → Hermes → Trenches, pm2 save

Rotate creds: z.ai · CF tokens · Pi Connect key · 2× Gemini

48h parallel run, then power the Pi down (don't wipe for a fortnight)

One-shot boot menuPick the USB — this is the installer one

Fast Boot eats the window? From Ubuntu: systemctl reboot --firmware-setup

ThinkPad / IdeaPad

Lenovo laptop

FnLock trap — top-row keys fire media unless Fn is held. Toggle with Fn+Esc.

Power

Pi 5 buttonPress to boot · press once running = clean shutdown · hold ~10s = force off

Won't boot? Green LED blinks an error pattern — count long/short and match the bootloader codes.

Field manual the one-liners

systemd — is it running, why did it stop

systemctl status ollama journalctl -u ollama -f systemctl list-units --failed journalctl -b -1 -p err # errors from last boot

storage — what killed the last install

lsblk -f # ALWAYS before a mount/dd/install df -h # watch / and /var sudo du -xhd1 / | sort -h | tail

Root full: sudo journalctl --vacuum-size=200M, pm2 flush, sudo apt clean. Permanent: pm2 install pm2-logrotate.

network — who's listening, who's reachable

ss -tulpn # every listening port + owner ss -tulpn | grep 11434 # who owns Ollama tailscale status tailscale ping kay2nuc

PM2 — the daily driver

pm2 ls # watch the ↺ counter pm2 logs clive --err pm2 restart clive && pm2 save

A climbing ↺ is a crash loop, not uptime. Read --err before restarting harder.

chroot rescue — won't boot at all

sudo mount /dev/nvme0n1p2 /mnt sudo mount /dev/nvme0n1p1 /mnt/boot/efi for d in dev proc sys run; do sudo mount --bind /$d /mnt/$d; done sudo chroot /mnt

Inside: apt --fix-broken install, update-grub, clear whatever filled the disk. Exit, reboot.
