we have a 2-node drbd set up.
the 'main' i/p address for each node is on a wire that goes to a managed switch.
when the switch is power cycled we have cluster communication problems, as expected. [ we have another switch on order to set up redundancy ].
However we have a nic on each node used for drbd communication. there is a patch wire directly connecting the 2 nodes using the drbd nics.
So I think it would be more reliable to use the drbd nic for cluster communication.
Unless it is a bad idea to do that, how to i change the 2 nodes to use the drbd addresses ? which files to edit?
