Hi, Andrew Thanks for a quick turnaround. > The one I linked to in my original reply does: > https://github.com/ClusterLabs/resource-agents/blob/master/heartbeat/rabbitmq-cluster I do not have logs of testing of this script. Maybe, Bogdan has something to tell about results of testing this

Re: [openstack-dev] [HA][RabbitMQ][messaging][Pacemaker][operators] Improved OCF resource agent for dynamic active-active mirrored clustering

Hi, Andrew Let me answer your questions. This agent is active/active which actually marks one of the node as 'pseudo'-master which is used as a target for other nodes to join to. We also check which node is a master and use it in monitor action to check whether this node is clustered with this

Thank you Andrew. Answers below. >>> Sounds interesting, can you give any comment about how it differs to the other[i] upstream agent? Am I right that this one is effectively A/P and wont function without some kind of shared storage? Any particular reason you went down this path instead of full

[openstack-dev] [HA][RabbitMQ][messaging][Pacemaker][operators] Improved OCF resource agent for dynamic active-active mirrored clustering

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
