Hi All,

Fairly new user to FreeNAS and semi novice linux user here who has made a terrible mistake - out of my own stupidity I've managed to wipe one of the disks in my zpool - long story but basically I made a mistake...

The most important data was backed up however there is other data which would be nice to recover if possible.

I'm using FreeNAS-9.1.1-RELEASE-x64 (a752d35), reading from similar issues on this forum I believe you'll want the below data.

So, what are my chances of recovering my data?

Since you were running a striped configuration I don't see any chance of recovery. Next time use a redundant pool type.

How did you wipe the disk? And which disk was it, ada2 or ada3?

ada0 was wiped - it now has an os installed on it.

Thanks for the advice, will keep it in mind for next time.

Cheers

Yeah, that's what I thought. If you just had deleted the partition table or something similar recovery might have been possible. Good luck next time.
