mirror RAID consistency

Is there any provision to automatically degrade a mirror RAID array (in
particular, a software array constructed with atacontrol) when the individual
members may have become inconsistent due to a crash or power failure?  I know
it would be a layer-crossing hack, but if there is a file system present, would
peeking at the superblock's clean flag on each member and degrading if any
aren't set be sufficient?
