Description John Eckersberg 2014-07-14 18:43:18 UTC
The HA rabbitmq manifest configues the cluster nodes via the lb_backend_server_names parameter.  However under staypuft, this is the FQDN of the nodes.  Rabbit requires the short hostname to be the node name, so for example you get this error using the FQDN:

# rabbitmqctl -n rabbit@5254000021ab.example.org status
Status of node 'rabbit@5254000021ab.example.org' ...
Error: unable to connect to node 'rabbit@5254000021ab.example.org': nodedown

=ERROR REPORT==== 14-Jul-2014::18:39:38 ===
** System NOT running to use fully qualified hostnames **
** Hostname 5254000021ab.example.org is illegal **


nodes in question: ['rabbit@5254000021ab.example.org']

hosts, their running nodes and ports:
- 5254000021ab.example.org: [{rabbit,35672},{rabbitmqctl14693,54770}]

current node details:
- node name: rabbitmqctl14693@5254000021ab
- home dir: /var/lib/rabbitmq
- cookie hash: soeIWU2jk2YNseTyDSlsEA==

The fix is to strip off the domain part of the nodes before passing into the rabbit class as the cluster_nodes param.
