Did I lost it all? Can't unlock pool. (Snapshots/CLone) Panicking!

Kind of panicking having lost all my data.

Basically, I was messing around with snapshots. The goal was to backup my pool (tank2)

  • I created a snapshot on another pool (snap1). Did some tests, tried to access snapshot but was unable for some reason. I think it was due to ACLs not being SMB. I messed around with the ACL type/mode of the snapshot but could not create an smb share to acess it.

  • I read about creating a clone. I did it as a test with the main level snapshot (with basically nothing since all data is nested below), then promoted it.

  • Then, I wanted to try something else. I deleted my snapshot dataset and all snapshots in tank2. Only one snapshot could not be deleted (unknowingly to me it was because it was used by the clone).

  • I restarted the system and now that’s where my nightmare started : My main tank 2 pool is not locked by the encryption root that is now the clone! (tank2/auto-2025-03-22_14-02-clone)

  • I see no option of unlocking anything anywhere, Tried to delete the clone dataset, but to do so, TrueNAS ask me to delete all childrens which are basically the whole tank2…

What can I do? Did I lost it all? How can I unlock tank 2 and delete the clone?

HELP!

Please try to keep calm and provide a much more detailed explanation of the situation.

Which tests? How is this snapshot “on another pool” related to the situation? Is it a snapshot from tank2 which could now be useful to restore?

Bad feeling about this…

Sorry, I’m not able to parse this sentence.
Please explain again. Do you had encryption to begin with? Have you tried to add encryption to the clone?
