My understanding is that it would just be rejected (I see some older solaris examples mention a "device too small" error). Best practice is probably to create a gpt partition of some standard size on the drives before adding that to the pool, to give a little adjustment room, though I confess I have made all my pools to date using the raw drives (other than a geom label); and simply try to replace drives with the same model.
