Disk failure, power loss, ZFS pool unavailable

[staticfactory]

I'm not sure what happened, but I do know that I wish I had a backup of the config...

I had a disk fail which set the pool to DEGRADED, and before I could replace the disk we had a power outage. Since then I have been unable to get the ZFS pool back online.

The dead disk isn't being detected by BIOS. There are 6 2TB disks in the pool (ada0-5).

The system is showing the pool as "Unavailable", and when I try 'zpool status' and 'zpool import' it is telling me that there are no pools. When I try 'zpool import -f" (or any variation of import switches) it tells me that it cannot import due to I/O error, and to "destroy and re-create the pool from backup".

I have tried just about every suggestion I have found in this forum to no avail. I have even tried replacing the disk, but there is no pool to add it to. I'm hoping that there is an order of operations that I am unfamiliar with to get this back online and get access to the 6TB of data (that is not crucial, but would definitely be a pain to lose).

I realize that you guys are probably pretty tired of this question, but I would really appreciate any help you could offer.

zpool import -F -d poolname or zpool import -f -d poolname

In desperation:

zpool import poolname -f -d /dev/mapper/

[staticfactory]

Every switch I throw at zpool import returns "Cannot import 'POOL': I/O error. Destroy and re-create the pool from a backup source."

Is there a way to destroy/recreate the pool and leave the existing data intact?

Are you sure of your hardware, cables, controllers, etc.?

Destroying a pool and recreating it destroys the data.

Destroying a pool and importing it with -f -d does not destroy the data.

Have you tried "zpool import poolname -f -d / dev / mapper /"?

Code: Select all

greedy: /# zpool import POOL -f -d /dev/mapper/

too many arguments
usage:
        import [-d dir] [-D]
        import [-d dir | -c cachefile] [-F [-n]] <pool | id>
        import [-o mntopts] [-o property=value] ...
            [-d dir | -c cachefile] [-D] [-f] [-m] [-N] [-R root] [-F [-n]] -a
        import [-o mntopts] [-o property=value] ...
            [-d dir | -c cachefile] [-D] [-f] [-m] [-N] [-R root] [-F [-n]]
            <pool | id> [newpool]

try importing the pool readonly

zpool import -o readonly=on poolname

[staticfactory]

Same issue....

Code: Select all

greedy: /# zpool import -o readonly=on POOL
cannot import 'POOL': pool may be in use from other system
use '-f' to import anyway
 greedy: /# zpool import -f -o readonly=on POOL
cannot import 'POOL': I/O error
        Destroy and re-create the pool from
        a backup source.

at this point you need to think on Format your Disk and restore data from a Backup ( or lose data if you do not have a Backup).

Thanks everyone... I was worried it had come to that. I have backups of everything that was important but it will definitely be a pain to lose the rest.
