Any HA block storage structure will have data corruption issues on 
failover if there was dirty write cache on the failed controller, unless 
it implements some form of cache mirroring.   cache mirroring is rather 
expensive performance-wise and not doable with any off-the-shelf 
software I'm aware of.
