I booted the 14.0-RELEASE installer and mounted zroot to /tmp/mnt. There's nothing in the zroot, except other mounts (like /usr, /home, and /var, the defaults). Those appear to have good data. But there's no /tmp/mnt/COPYRIGHT, /tmp/mnt/boot, etc. I did a very lengthy memtest on this machine without issue. I don't have any particular reason to suspect hardware. It's as if every file/folder directly under zroot/ROOT/default has vanished. There's no zpool errors. I made no changes to the filesystem in the boot prior to the reboot. -Henrich Apr 11, 2024, 23:32 by : > Hi, > > I have 14.0-RELEASE installed with two drives in a ZFS mirror on a x86_64 system.
