Hello. I'm glad to announce that the pacemaker OCF resource agent for the rabbitmq clustering, which was born in the Fuel project initially, now available and maintained upstream! It will be shipped with the rabbitmq-server 3.5.7 package (release by November, 2015) You can read about this OCF agent in the official guide [0] (flow charts for promote/demote/start/stop actions in progress). And you can try it as a tiny cluster example with a Vagrant box for Atlas [1]. Note, this only installs an Ubuntu box with a Corosync/Pacemaker & RabbitMQ clusters running, no Fuel or OpenStack required :-) I'm also planning to refer this official RabbitMQ cluster setup guide in the OpenStack HA guide as well [2]. PS. Original rabbitmq-users mail thread is here [3]. [openstack-operators] cross posted as well.
