I added the 4 drives, set the pool file system as ZFS-Encrypted, set it as raidz1, entered and confirmed the passphrase, started the array and selected to format the 4 drives. It then shows that it is formatting the drives for about a minute before stating "Unmountable: Unsupported or no file system".
Odd thing is, a regular ZFS pool works, as well as BTRFS and BTRFS-Encrypted pools, it is only ZFS-Encrypted that is giving me issues. I remember this being a bug a few versions back but thought it was resolved. I also thought to try manually importing using "zpool import 'pool name'", but it returns "no such pool available". I have attached the diagnostic zip and blkid output.
