Description
When the MDS reaches up:rejoin / up:resolve after spending a long time (hours) in up:replay, it often gets in an loop somewhere with the mds_lock. This causes it to miss heartbeat resets. Consequently, the beacon thread will stop sending beacons to the monitors.
Make the MDS smarter by:
- If replay took X time, lengthen the internal heartbeat grace period by some configurable factor during up:resolve/up:rejoin.
- Note in beacons a new health warning about long recovery during these states.
