ZFS pool broken after upgrading to 14.04 LTS
- by cruiserparts
Well, I have been putting off upgrading to 14.04 for fear that I would break something. Actually for fear that it would break zfs (or I would break it). I am bascially slightly better than novice at linux.
Spent the last couple of hours trying to get the pool back. Now I am at the stage where I don't think I have a complete failure, but I am worried that I may break it. So if could help me not break it, and recover it, I would be thankful.
My zfs is file storage and not boot.
It was working fine for a year and was working perfectly before the upgrade (scrub and everything was fine). I was confident that the upgrade would work (or at least I could fix it) because I had upgraded once in the past, the pool went missing, but I was able to get it back.
I have reinstalled zfs, zfs utilities, and some dependencies (after searching this forum)
I think what happened is 14.04 deleted some config file, or specified disk names differntly, but I could be wrong. When I set the pool up originally, I was using specific device Ids as I recall (because I did not want to break things if they got reassigned at boot)
So see if this helps.
I can confirm that old mountpoint folders are there but empty.

status: One or more devices could not be used because the label is missing
or invalid. There are insufficient replicas for the pool to continue
functioning.
action: Destroy and re-create the pool from
a backup source.

___@ourserver:~$ sudo zpool import naspool1
cannot import 'naspool1': a pool with that name is already created/imported,
and no additional pools with that name were found
___@ourserver:~$ sudo zfs list
no datasets available
What other output can I post to help? I'm thinking the update deleted some zfs config files. It seems like the pool exists and certainly 3 perfectly working disks did not fail at once. I am worried that I may break something without a little bit of guideance.
Thanks.
