Good morning, This is the first time I've been in this situation with my pool and I can't find a solution. I am on Truenas-13.0-U5.3. My pool has gone offline and since then I can't import it back into Truenas. I tried with the GUI and I got I/O and python errors. Here is the information I can give. Thanks for your help.
zpool import

Destroy and re-create the pool from
a backup source.
