Comment 2 for bug 1516631

Reproduced locally:
after shutdown node-1 only controller is shown up in pacemaker:
Master/Slave Set: master_p_rabbitmq-server [p_rabbitmq-server]
     Slaves: [ node-5.test.domain.local ]

rabbit on node-5 isn't alive:
root@node-5:~# rabbitmqctl cluster_status
Cluster status of node 'rabbit@node-5' ...
Error: unable to connect to node 'rabbit@node-5': nodedown
