Thanks for sharing.
It probably doesn't make a huge difference in what happen but what OS (linux, distro, start9, etc..) where you running LND on?
Debian Linux 12 lnd 0.17.3 - no start9/umbrel or similar, just compiled from sources

Did you use zfs from Debian contrib?
reply
no, zfs from bookworm-backports. Version zfs-2.1.12-0-g86783d7d9-dist according to zdb -h , updated to zfs-2.2.2-0-g494aaaed8-dist just before the fatal reboot.
