Normally (depending on what packaging you are using/how DRBD is installed) it will hang during the init process until either the secondary node shows up, or you tell it to stop waiting (which shouldn't be done unless you're sure that's what you want) b) turn auto_failback to OFF in Heartbeat (ha.cf). It confuses things and is not normally required with DRBD. c) are you sure the machines are still connected properly (check firewalling etc.). This sounds like split brain. > and the secondary goes into secondary/unknown, why they are not able to sync again? Look at your logs. They will tell you why. > Does this require any change in the parameters (time etc.)? Nothing to do with time. Tim
