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>

Incus host on the LAN.
- 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)
- USB 4 TB WD Red: ZFS pool
usb4t—usb4t/backup→/backup(incus exports,nuc/+ks4/subdatasets, 1 TB quota) andusb4t/media→/srv/media(media library, shared into containers viashift=truedisk 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
- Backups: all local instances replicated to the USB pool
