One of our systems have had a controller down.
We changed the controller and repaired the zfs with scrub.
Everything seemed to be ok, but with
zpool status -v
we get following message:
pool: zDataStorage8
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.

errors: Permanent errors have been detected in the following files:
<0xffffffffffffffff>:<0xa0>
We do not know, if we have to restore our pool due to this message.
=> we transfer all snapshots to a backup-pool. That pool is totally ok so the error is not transported to the backup.
