[rabbitmq-discuss] Failover in Clustering mode

Mon Sep 3 14:56:38 BST 2012

Thank Francesco and  Matthias.

Oh, I'm sorry for leaving stupid question.

Yes, I killed disc node(node1), and I tried to make a queue which has the
same name that node1 has.

and Matthias. your answer is very clear.

and I understood that clustering mode is different from mirror mode. I
thought it does something like mirror mode.

and, If I want to support Failover, I have to run rabbitmq as mirror mode.

Thank you.
