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 settings. -Ben
