I have no idea what magic your raid controller has, but unless it understands filesystems, this is really asking for trouble. You have two similar but slightly different filesystem images. You are going to "merge" them? I assume/hope the the raid card just picked one drive as the winner and is going to wipe the other, because that's the only way this could work.
