Both hosts were powered off and brought back from a cold start, which is the first real test of everything built on 2026-08-30. nas: both pools imported from /etc/zfs/zpool.cache, all instances autostarted, NFS exports republished, 0 failed units. nuc: /dev/dri present with 0 i915 warnings (booted with the display unplugged), NFS auto-remounted, VAAPI transcode at 9.5x realtime. Records the ordering that actually cleared tank's inherited <metadata>:<0x0> and <0x3d>: a scrub alone found 0 errors and repaired 0B but left them, and a plain `zpool clear` afterwards did not drop them — ZFS flushes the persistent error log on a scrub run *after* the clear. That matters beyond tidiness, because while those entries stand `zpool status -x` reports the pool unhealthy forever and zpool-health.sh cannot signal anything new. Two kiosk corrections, both from observed behaviour: - the Pioneer DAC being switched off is the most likely cause of "video, no sound" — asound.conf pins the ALSA default to it by card name, so `default` fails to open outright and mpv falls back to null silently. Adds the one-line aplay check. - hotplugging the display makes cage exit once and Restart=on-failure recovers it ~5s later. Do NOT restart it by hand; check ActiveEnterTimestamp against the hotplug time first. Also flags that the OS mirror is still untested with a disk physically unplugged — it is a guess until then.

Homelab: nuc
Incus host on the LAN — on-demand: since 2026-08-30 it only needs to
run when watching Jellyfin or using the Spotify Connect kiosk. Everything
always-on (blocky/DNS, privoxy, transmission-bt) moved to
nas, which is why nuc can now be powered off.
⚠️ Powering nuc off has backup consequences — its 03:30 replication to nas only runs while it is up. See nas-install.md §9.
-
Debian 13, Intel Alder Lake-N (iGPU
i915, shared by both Jellyfin containers) — bare-metal reinstall: nuc-install.md -
Instances are bridged onto the LAN (192.168.0.0/24)
-
Storage: ZFS pool
dataon the SSD (all instance disks). The USB 4 TB and its pool left nuc on 2026-08-30 — the enclosure's JMicron bridge was suspending the pool (usb4t-dropouts.md); the disk now sits on direct SATA innasas pooltank. -
Media library:
/srv/mediais now an NFSv4 mount from nas (192.168.0.4:/media, read-only).jellyfin-serverstays here for the iGPU and reads it withshift=false(jellyfin-server.md). -
Backups: nuc and nas cross-replicate — nuc pushes all its instances to
nas:nucbackupat 03:30, nas pushes its own tonuc:nasbackupat 04:00, so neither host's instances depend on that host surviving (nas/nas-install.md §9). The ks4 pull leg moved to nas as well (ks2/nas-seed.md), so nuc no longer runs a WireGuard tunnel. -
⚠️ Never reboot nuc with the display powered on — the i915 probe dies and takes every container with it (including LAN DNS). Symptoms and fix: jellyfin-client.md
Instances
| Name | IP | Doc | Features |
|---|---|---|---|
| jellyfin-server | 192.168.0.5 | ✅ | unprivileged, autostart; iGPU render node (gpu device, render gid) for QSV/VAAPI transcoding; /srv/media disk device (NFS from nas, shift=false, read-only); proxy device → host :8096 |
| jellyfin-client | 192.168.0.6 | ✅ | privileged, autostart; full iGPU (gpu device, gid 44) → HDMI kiosk (cage + Jellyfin Media Player); custom raw.lxc (bind /dev/snd, /dev/input, host /run/udev); Pioneer USB audio as ALSA default; FR keymap; go-librespot Spotify Connect ("Pioneer A-70") |
| homeassistant | (stopped) | — | virtual machine, 50 GiB root disk on pool data |
Moved to nas on 2026-08-30: transmission-bt
(next to the media dataset it writes to), plus blocky and privoxy
so LAN DNS and the proxy survive nuc being shut down.
