Ah. Well that answers it. I'll fail unloading of the module if devices are open. This leads to a curiosity as to how the RAID failover modules work at all. I guess if you abstract the real disk(s) under a logical disk you can change the bottom layer without affecting the top. I'll have to look at that code a little closer.
