I am running two pools (8-disk RAID-Z2, a single USB backup disk) with encryption. A few days ago I updated from 11.3u1 to 11.3u2 and motherboard BIOS and IPMI (SM X11SSH-F) as well. I rebooted the system since then several times and decrypted my pools each time sucessfully.
Planning to test/add L2ARC i shut down the system and added a USB3/SSD device and after booting, i cannot decrypt my pools anymore:
I had navigated to Storage, Pools, Add (wrong place to add L2ARC, i know) where i saw my disks all listed as available - see screenshot. I didn't do anything there (Create button was greyed out all time)
I exported the backup pool and tried to import it, then the system said there were no pools to be imported.
I switched to the console and looked at gpart list and inside /dev which only shows partiiton information for the used boot pool. All 8+1 data disks are only listed as the device itself without partition information - if i am not mistaken.
Contact me, you can take a look at the system yourself.
The following information i saved years ago after creating the pools, how it looked like. Exemplary for ada6.
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.
