Some apps's data may need to be synced before it's safe to promote/demote/standby.
For example - DRBD, it replicates data across servers, but if you shut down master server during resync - you'll have a split brain. Is there a way to tell pacemaker from OCF agent that it's not safe now to do any migration? Unfortunately, I didn't find anything about this case in https://github.com/ClusterLabs/resource-agents/blob/master/doc/dev-guides/ra-dev-guide.asc _______________________________________________ Users mailing list: [email protected] https://lists.clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
