When you run it on the first disk in the raid it sets the raid up as waiting for the rest, creates the /dev/md/xxx device, all looks good. When you try the second disk (I have a raid-1) it complains that the /dev/md/xxx exists and does nothing. Results - exactly as "fibre raid" complains - you're left with a partly set up inactive raid. Haven't got around to doing a bugreport yet as I don't want to mess with my running server.
