I setup unraid a few days ago and successfully "imported" and existing zfs pool. (raidz1, 2vdevs of 2 devices). Last night I stopped the Array in order to try and use the unassigned disk plugin to mount a disk before adding to array. when I restarted the Array, my pool status showed up as "Unmountable: wrong or no file system". I've removed the pool and tried to import again (after a start without the pool), but I continue to get the same status.

Are there other commands I should try or guidance on recovering my pool?

I tried a manual import from the cli. All of the commands return "cannot import 'media-pool': no such pool available"

zpool import -a

zpool import -f media-pool

zpool import -F media-pool

zpool import -FX media-pool

zpool import -fD

zpool import -d /dev/

zpool import -d /dev/disks/by-id/

zpool import -d /dev/disk/by-uuid/ -a

The zfs labels are intact on all disks

• zdb -l /dev/sdc1

So these labels are on the partition and not the raw disk. zpool also can't read labels 1,2,3.

I attempted to repair the label and got following. trying to figure out what this means

> zhack label repair /dev/sdc1

Is the above the full output from zdb -l? Also, please post the diagnostics.
