It seems, that while testing suspend to RAM on my machine by running
"acpiconf -s 3" I managed to break a RaidZ zpool. The machine went to
sleep fine, but after waking up commands (e.g. reboot) reported I/O
error. When booting after a hard reset the machine fails to mount the
root filesystem:
Trying to mount root from zfs:/vault/root []...
Mounting from zfs:/vault/root failed with error 5.
I booted the system from FreeBSD-9.1-RELEASE-amd64-memstick.img and
tried to import the zpool in the shell:
# zpool import -f vault
cannot import 'vault': I/O error
Destroy and re-create the pool from
a backup source.
Command "zpool import -nfF vault" from the memstick system gives no
output. (I thought it should always give some output?)
What should I try next to repair the zpool or recover the data? I
started "zpool import -nfFX vault" but it seems to take quite long.
Some more information about my system:
zpool vault consists of 5 block devices:
whole disks: ada1, ada2, ada3
cache: ada0s1e
log: ada0s1d
The system boots from a UFS filesystem ada0s1a. The zpool and rest of
the system was created with FreeBSD 9.1-RELEASE.
