[rabbitmq-discuss] Recovering an 3-node cluster after power failure

Mon May 20 13:35:47 BST 2013

Hi.

If you just want to do the equivalent of "rabbitmqctl reset" with a node 
down, then deleting the Mnesia directory (see RABBITMQ_MNESIA_BASE in 
http://www.rabbitmq.com/relocate.html for location) is the simplest 
thing to do.

If you want to remove a node from a cluster and the lack of that node is 
preventing you from starting the cluster, you can set RABBITMQ_NODE_ONLY 
for another node, and then invoke "rabbitmqctl forget_cluster_node" 
against that.

Cheers, Simon
