See attached, tried again and can't make zfs stick as a type when added to a pool, always reverts back to auto, and once created and I select format from Array Operations tab, always btrfs.
I can create a single zfs pool, but RAID0 zfs pool no sucess and what is odd zpool list show both correctly, ZFS Master plugin shows both pools correctly as RAID0, but from Pool Devices tab shows unmounted/unrecognized FS and the same from the Array Operations Tab, see pics below:
