ZFS: Input/output error when mounting

[zmanbb]

Hi

After power outage one of my ZFS shares cannot be mounted any more.

I have three volumes (all on the same physical drive):
1. RAID -> /mnt/RAID
2. RAID/datoteke -> /mnt/RAID/datoteke
3. RAID/dokumenti -> /mnt/RAID/dokumenti

When trying to mount RAID/dokumenti, error occurs: "cannot mount 'RAID/dokumenti': Input/output error".

Has anyone expirienced something similar? How can I fix this error?


Thank you

Code:

[root@freenas] /var/log# zfs mount RAID/dokumenti

After running scrub on the volume the "zpool status -v" output is:

Code:

[root@freenas] /var/log# zpool status -v
  pool: RAID
 state: ONLINE
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.

Hello, Zmanbb

Were you able to resolve this issue?
I am having similar problem and would like to know if there is a fix.
Or at least something that would allow me to mount (and read) such pool.
