There is no reason to think about a direction. I'm talking about direction because in my case sync from server B to server A works fine, but from server A to server B -- fails. Since it's initial sync of newly created volume, it doesn't matter for me which of the hosts to make Primary, and which -- Secondary. So, that initial sync may be performed in two directions -- from server A to server B, or from server B to server A. In my case when I mark server B as primary, everything is fine, drbd synchronizes from B to A. But if instead I mark server A as primary, synchronization won't perform -- there are protocol errors in the log. I tried to use different versions of drbd, and found out that this issue starts with 8.3.11. Right now drbd performs synchronization from A to B with 8.3.10, but I couldn't make it do that with 8.3.11, 8.3.12 and 8.4.1. In my experiments each time I do the following: 1) "create-md" on both servers 2) starting the resource on both servers 3) marking one of the servers as primary
