AW: Failsafe, shared SCSI, and linux's software RAID

I don't think oyu'll be happy with the result: software raid only marks a
raid array as "clean" during normal shutdown of the system (or unload of raid
drivers). On startup, the whole raid device will be resynchronized if it
wasnt shutdown cleandly before; 

Since a failure of the primary node won't cleanly shutdown the raid device,
you'll get  a raid resync on every failover.

For shared storage, I'd really recomend an external raid enclosure.
