As I understand it, DRBD only knows about modifications to the
resource as they move down the stack( DRBD -> RAID -> DISK ). Since a
broken RAID array happens at a lower level than the DRBD resource,
it's not going to start pushing those changes across. It should,
however, receive an IO error and respond to that based on your config
