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 command
root@:/root # zpool import -nfFX vault
returned after few hours:
Would be able to return vault to its state as of Sun Feb 17 03:07:36 2013.
Would discard approximately 20 minutes of transactions.
So I ran
root@:/root # zpool import -fFX vault
and few hours later returned:
Pool vault returned to its state as of Sun Feb 17 03:07:36 2013.
Discarded approximately 20 minutes of transactions.
After that I could import the pool in the memstick environment. I
unmounted all ZFS file systems and exported the zpool and rebooted.
However when the system boots from the UFS root it fails to mount root
from ZFS:
Trying to mount root from zfs:vault/root []...
Mounting from zfs:vault/root failed with error 2.
To get the system booting from ZFS root I tried several things including:
- recreating the /boot/zfs/zpool.cache,
- cloning the vault/root file system to vault/new_root,
- setting the mountpoint of the root file system to / and legacy,
- removed the cache and log devices from the zpool.
I finally gave up and copied the contents of the vault/root file system
to a UFS file system at ada0s1d and changed the system to mount root
from there. /tmp, /usr and /var are mounted fine from the ZFS.
I really would like to back using the ZFS root file system. I documented
the commands I used in the memstick environment and dmesgs of the
failing ZFS boots and made them available here:
http://upload.egarden.fi/ultra40_zfs_fail
Maybe someone can figure out what I'm doing wrong? Before the suspend to
RAM incident the system booted up just fine.
I used the following trick to get the dmesgs: when the system booted up
and failed to mount the ZFS root I entered ufs:da0 to the mountroot>
prompt to get in to the memstick environment.
