Hi there, I'm using Heartbeat 2.1.4 and DRBD 8.2.7. I have a problem using Split Brain during recovering. I have two node cluster in active/pasive way. During normal operation, the master node runs drbd as primary role, while slave node runs as secondary role. For testing purposes, I unplug the ethernet cable, and because of that, they have no comunication (so Split Brain is expected to occur when plug again). In this situation, the master node shows DRBD as "primary/unknown" and the slave node shows "primary/unknown". This situation is considered ok, and there is no problem because this is the expected behaviour. The problem arises when the ethernet cable is plugged again and the comunication is up again. Master node allways shows "primary/unknown" and slave node remains in "primary/unknown" for about 90 seconds. After that, salve shows "secondary/unknown" I would like to know: Why is Heartbeat taking so long to "demote" the slave node from primary to secondary? I had to increase "cluster-timeout-action" to 120 seconds.... DRBD never recovers "primary/secondary" state after Split Brain, even if drbd.conf is configured to discard changes in younger primary (that's what I need): after-sb-0p discard-younger-primary; after-sb-2p violently-as0p; What can I do??
