DRBD can have sync in progress, and be operational at the same time. ther are several cases: everything normal. one node fails, the other either is already primary, or becomes primary. the failed node comes back and will become sync target. heartbeat now can decide to fail services back to that node, or chose to leave the services running where they are. though for stability reasons (think of network failure) it is preferable to not relocate services to a sync target. the resource agents and hearbeats decision making process needs to be improved there.
