Yes, I believe that you answered my question.  My concern was indeed how to "replace" node B with a new node operating in its place.

Thanks again!  The responsiveness that you guys offer is amazing!

Hmm. I'm not sure I fully understand. Are you asking how to set up a new node B from scratch such that it can replace the old node B, or how can you remove B from the federation leaving A and C, and remove the federation infrastructure for B on A and C?

If the former: ensure the new node has the same DNS name as the old, and set its local node name
(http://www.rabbitmq.com/federation.html#other-config) to be the same, and the other nodes should connect and pick up where they left off.

If the latter: just delete the appropriately-named queues (scripting with rabbitmqadmin and grep may help here). Or set a queue expiry in the first place and they will be automatically deleted after a while.

Did I understand correctly?
