If you know for a fact that /dev/sda isn’t in use (I’d confirm with grep sda /proc/*/mountinfo), then you may need to wipe its beginning so that ZFS doesn’t consider it to be used.

You’d normally do dd if=/dev/zero of=/dev/sda bs=4M count=10 to achieve that, but first make very very sure that the ZFS error isn’t correct as if that drive is used for your bootloader, swap or anything else, you’ll have a very very bad day :slight_smile:
