No, I don't have Dual primary. My DRBD is in Single-Primary mode for both DRBD resources. I use N+1 setup. I have 2 resource group which have unique Primary and shared secondary. pbx_service_01 resource group has primary node-01 and secondary node-03 pbx_service_02 resource group has primary node-02 and secondary node-03 I use asymmetric cluster with specific location constraints in order to implement the above. The DRBD resource will never be in primary mode on 2 nodes at the same time. I have set specific collocation and order constraints in order to "bond" DRBD ms resource to the appropriate resource group. I hope it is clear now.
