I would guess not if you did a full create, but I'm very suprised that
worked as without specifying the additional device parameters the create
should fail so its rather hard to confuse the two.
In addition I would also expect create to check for an already existing
pool on the devices before allowing you to proceed. If thats not the case
it would be a worth while check to add IMO.
