Recovering encrypted zpool after previous TrueNas usb device failed.

[darkcloud784]

I posted this in TrueNas General forum but realized it may fit here better.

So my USB drives (mirrored) both died within the past 24 hours (unsure how they both died at the same time but they did). I have one zpool that is unencrypted and another that is encrypted. I have re-installed truenas core 12 on another media and imported the zpool that is unencrypted but I am unable to import the encrypted one. I have tried uploading the .tar config to system->general but it says "
Error:[/B] [EFAULT] The uploaded file is not valid: local variable 'numsouth' referenced before assignment".

I've also tried using the pwenc_secret provided to import the zpool but it fails to attach.

Code:

What am I doing wrong here? Is there a way for me to recover my encrypted pool?

To unlock the encrypted pool (if it was encrypted with OpenZFS 2.0 style encryption) you need the key file you were prompted to save when you created it, not the config file you saved.

If it's encrypted with the FreeNAS geli method, I hope one of the other forum members with more experience can assist (but normally you would see ".eli" at the end of the GPTids, so perhaps it's what I suggested).

The zpool was created prior to 11.3, but I updated to truenas and imported and upgraded the pools just before I had the device failures. Unsure if this changes anything.

The new encryption system is different... you can search the FreeNAS forums for importing a geli encrypted pool as it's the legacy method that you need to use.

Maybe this one will get you to an answer somehow... take care before doing anything you may later regret.

SOLVED - Unable to import pool of encrypted drives in GUI [FreeNAS 11.2-U6]

On a Mini XL with 8 x 12TB drives in a RAID-Z2. For a variety of reasons, I in-place encrypted the drives under 11.2-U4.1 using the instructions from here. It was "simple" if time-consuming. I have the geli key and passphrase. Unfortunately, I did not re-import the pool into FreeNAS...
