>From the description it appears that at one time the whole disk was formatted as zfs and that those file system signatures remain.
You can check what is going on with the following two commands: sudo blkid /dev/sda sudo wipefs --no-act /dev/sda To fix you will likely need to remove the extraneous file system signatures. The wipefs command can help you remove the specific incorrect signature.
