Hi everyone, I have done some tests by now on my two node cluster with different bond modes. I have two NICs on each node for direct connection and no switches in between. It turned out that in 'active-backup' mode the assignment of the NICs to each other does matter. I.e. if the wrong NICs are connected the bond link does not work. That problem does not occur with 'balance-rr' and 'broadcast'. I'm going with balance-rr. In this mode I was even able to swap the two networkcables without corosync and a running drbd sync getting interrupted.
