Be careful here, as this does:

“When a disk experiences a failure and becomes unavailable, the recovery 
procedure will first attempt to restart the disk and if this fails, the disk is 
suspended and its data moved to other disks. “

Which may not be what you want to happen. :-) If you have disks marked down due 
to a transient failure, kicking of restripes to move the data off might not be 
the best choice.

If you do a "mmchconfig restripeOnDiskFailure=yes", such a callback will be 
added for node-join events.
