Nightly replication had been failing since Aug 17 behind a misleading incus error; root cause is a JMicron USB bridge dropping off the bus (61 disconnects in 30 days) and suspending the pool — the disk itself is SMART-clean. Records the recovery (clear/scrub), the damage, the ordered fixes, and why nothing alerted: zed was running without an MTA on the host. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# Homelab: nuc
|
|
|
|
Incus host on the LAN.
|
|
|
|
- Debian 13, Intel Alder Lake-N (iGPU `i915`, shared by both Jellyfin containers) —
|
|
bare-metal reinstall: [nuc-install.md](nuc-install.md)
|
|
- Instances are bridged onto the LAN (192.168.0.0/24)
|
|
- USB 4 TB WD Red: ZFS pool `usb4t` — `usb4t/backup` → `/backup`
|
|
(incus exports, `nuc/` + `ks4/` subdatasets, 1 TB quota) and
|
|
`usb4t/media` → `/srv/media` (media library, shared into containers
|
|
via `shift=true` disk devices; works because ZFS ≥ 2.2 supports
|
|
idmapped mounts)
|
|
- ⚠️ The USB enclosure drops off the bus periodically and suspends the
|
|
pool, which silently breaks the nightly replication — symptoms,
|
|
recovery and fixes: [usb4t-dropouts.md](usb4t-dropouts.md)
|
|
- Backups: all local instances replicated to the USB pool
|
|
(`/root/scripts/incus-copy.sh -p backup -s nucbackup`; replicas
|
|
stopped, autostart off) — see
|
|
[nuc-install.md](nuc-install.md); ks4 replicas pulled into
|
|
pool `ks4backup` — see [ks4/incus-copy.md](../ks4/incus-copy.md)
