Pool locked after upgrade to 24.04

I’ve run into an issue after upgrading from 13.0-U6 to 24.04.2.5. The pool is not locked, and there are no unlock to be found anywhere in the GUI.
When I click the pool in the GUI, only option presented is to export the pool.

I did go through the preparation page, before the upgrade. and to my knowledge, I don’t believe it was encrypted with GELI encryption.

How do I unlock the pool?

Main difference being that a quick wipe should be enough to solve the issue, a wipe to zeros certainly also works but takes a much longer time. In my setup I am using a simple mirror with two HDDs.

To elaborate the steps for each option in more detail: Option 1: Recreate the pool This is useful if you don’t have any data in the pool. This does destroy all data in the pool. Export the pool in the UI. Do not select the “Destroy data on this pool”. Tick “Confirm Export/Disconnect” checkbox and press “Export/Disconnect” Go to the disks screen. Click on each disk …

Thank you for the response and the references. Ones I imported the pool, it appears to be working fine. No warnings or alerts, and the pool is available upon reboot as well.
I also successfully updated from 24.04 to 24.10, and everything still appear to be working fine.

I had the same issue after upgrading to 24.04 form Core, but exporting/re-importing pools had no effect. Re-uploading my config from before the migration fixed it. Just wanted to comment in case it helps anyone in my situation who found this thread.
