Doc Type: Bug Fix
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.

Description Michele Baldessari 2016-02-23 02:41:59 EST
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)
