Title:
ZFS unrecoverable error after upgrading from 20.04 to 22.04.1
Status in zfs-linux package in Ubuntu:
Confirmed
Bug description:
I have a server that has been running its data volume using ZFS in
20.04 without any problem. The volume is using ZFS encryption and a
raidz1-0 configuration. I performed a scrub operations before the
upgrade and it did not find any problem. After the reboot for the
upgrade, I was welcomed with the following message:
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.
see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-8A
The volumes still do not have any checksum error but there are 5 zvols
that are not accessible. zpool status displays a line similar to the
below for each of the five:
errors: Permanent errors have been detected in the following files:
tank/data/data:<0x0>
I run a scrub and it has not identified any problem but the error
messages are not there and the data is still not available. There are
10+ other zvols in the zpool that do not have any kind of problem. I
have been unable to identify any correlation between the zvols that
are failing.
I have seen people reporting similar problems in github after the
20.04 to the 22.04 upgrade (see
https://github.com/openzfs/zfs/issues/13763). I wonder how widespread
the problem will be as more people upgrades to 22.04.
I will try to downgrade the version of zfs in the system and report
back
