What commands did you run to ensure the disk was clean? For example did you zero out the entire disk device with: sudo dd if=/dev/zero of=/path-to-disk-device Prior to creating ZFS did you check for file signatures on the disk with: sudo wipefs /path-to-disk-device The wipefs command without any flags reports all signatures on the disk device and does not change the disk.
