testing DRBD9, I set up a three-node-cluster, with my resource mirrored on all three of them.
Then I simulated hardware failure by taking out one of the nodes.
The replacement would be another server which is already doing DRBD (for other resources).
So,  name and IP address (and node-id) cannot be set to the ones of the failed hardware (easily).

I did not get this to work except by the procedure I found previously for the expansion of 3->4 nodes: dump metadata, edit the dump to add a slot, 
reload the metadata.

Is there any other way to convince DRBD to accept a new peer?
