Hi Tim, Yes, I really rurned one of the servers off? The primary server waited for some time on boot up and then came up. I want the auto-failback on ? do we have a solution to this? Yes, the servers were connected, even if I shutdown the heratbeat the disk is shifted to the secondary server, but they remain in standalone mode, the drbd can talk to each other as the (Secondary server) changed states from primary/unknown to secondary/unkown. but remain standalone. I do not understand why? can't find much in the logs, what thing should I look for specifically? Is it ok to start the heartbeat and the drbd processes at boot time automatically?
