-**hf-pdocker-02 fixed 2026-11-04 after the 11-03 power event** (dockerd was dead 27h: stale Swarm membership made it fatal-exit when .192:2377 was unreachable, and `/mnt/docker-data` had not mounted): `docker swarm leave --force` done, and the `/mnt/docker-data` fstab line now has `nofail,x-systemd.after=network-online.target,x-systemd.mount-timeout=60s` (backup `/etc/fstab.bak-20261104-nfs-nofail`). Its other NAS lines (`/mnt/infrastructure`, `/mnt/NAS` cifs, `/data/media`, `/mnt/nas-media`) still lack it. **bart and .192 still report `Swarm=active`** -- .192 is the old manager so it boots fine; bart would fail the same way as .100 did if .192 is down at boot (not yet fixed, user approved only .100).

Fixed by restarting all 18 containers DBs-first. When doing bart: restart its containers or dockerd right after `swarm leave`**), and the `/mnt/docker-data` fstab line now has `nofail,x-systemd.after=network-online.target,x-systemd.mount-timeout=60s` (backup `/etc/fstab.bak-20261104-nfs-nofail`).

 **NFS mount (all nodes):** `192.168.86.30:/volume1/Docker /mnt/docker-data nfs rw,soft,timeo=300,intr,_netdev,nfsvers=3,nofail,x-systemd.after=network-online.target,x-systemd.mount-timeout=60s 0 0`
 **Note (hf-pdocker-01):** Both NFS mounts hardened with `nofail,x-systemd.after=network-online.target,x-systemd.mount-timeout=60s` on 2026-05-20 to prevent boot-time race (network not up when NFS tried to mount, cascading ~10 container failures).
