Doc Text:	The notify=true parameter was previously missing from the RabbitMQ Pacemaker resource. Consequently, RabbitMQ instances were unable to rejoin the RabbitMQ cluster. This update adds support for notify=true to the pacemaker resource agent for RabbitMQ, and adds notify=true to OpenStack director. As a result, RabbitMQ instances are now able to rejoin the RabbitMQ cluster.	Story Points:	---

Description Michele Baldessari 2016-02-23 07:41:59 UTC

Description of problem:
Sometimes when a controller is rebooted the node is unable to join the rabbitmq
cluster. This issue needs the following to happen to be fixed:

1) BZ https://bugzilla.redhat.com/show_bug.cgi?id=1247303 needs a fix in the resource agent (see this BZ for more history about this issue)

2) We need to add the meta parameter "notify=true" on fresh installs and on updates.


Note, that if the fix to THT makes it in before the fix of the resource agent,
nothing happens (i.e. things keep going like before)
