Kosti Posted January 3 Share Posted January 3 So I had a power outage and server rebooted only to find the array stopped due to missing key. I do not recall the passphrase I used sometime back when I converted my cache drive to zfs when 6.12.4 was released Am I shit out of luck to reset the key? Being the cache drive is the only zfs formate file system is there a simple recovery method? The permit reformat - will that destroy all the content of the 4 x 12TB & Parity drives? I do have a backup to an external 20TB drive mainly the folders that I wanted to backup, not sure if it included dockers or the USB drive on that backup. If I remove the cache from the array & format it will it bring me back to the same place with a missing key or is the encryption across the whole array? Only the cache drive is formatted as ZFS and for some reason I'd chosen encryption just not sure if its only on this cache drive and I can get the array started again? What Options are available for stupidity? Quote Link to comment
JorgeB Posted January 3 Share Posted January 3 If you don't know the key there's no way of recovering, that the point of using encryption. 1 hour ago, Kosti said: The permit reformat - will that destroy all the content of the 4 x 12TB & Parity drives? It will allow re-formatting of any encrypted volumes, deleting all data there. Quote Link to comment
Kosti Posted January 3 Author Share Posted January 3 Thanks, how many times can I keep trying to guess it? Quote Link to comment

Kosti Posted January 24 Author Share Posted January 24 Sorry been stuck with work and no time to play with the server as its been shutdown since I can't bring up the array. so one more question before I close this out as resolved Can I revert to my previous unraid version of 6.9 and will this resolve my passphrase issue? Is there a way I can restore to this from a back up of the USB as I went from 6.9.2-->6.14 but I am pretty sure I backed up the USB and most of the unraid before I went to a newer version of unraid I know its a long shot but just maybe I can trick the system, the only issue I can see is maybe the cache drive went from XFS to ZFS encryption, damn it I just don't want to reinstall everything Now looking at Bitwardern or similar to manage my PW since my grey matter is failing me - I'm such an idiot !

You can downgrade but not sure that will make a difference, copy just the bz* files from the v6.9.2 backup replacing current ones. 1 Quote Link to comment

Kosti Posted January 28 Author Share Posted January 28 OK, thanks guys, I am going to attempt to downgrade and see what happens as either way I am locked out due to making the passphrase in the first place, should've stuck with dumbo 123! Only encryption done is the cache drive, no other drive and that I changed the cache drive from XFS to ZFS Will be a good test, but when I get a chance to turn it on, I am going to give this a try as potentially only the cache drive will need reformatting Quote Link to comment
