Description of problem: In the case pacemaker-remote (OS::TripleO::Services::PacemakerRemote profile) node is being deployed within composable roles topology we should lower pacemaker property of cluster-recheck-interval to much lower value from default value which is 15mins. The reason is that even though we set ocf:pacemaker:remote attribute reconnect_interval to 60s it's not guaranteed to be performed more frequently than the value of the cluster-recheck-interval cluster option and the consequence is that in a case of failover pacemaker_remote node is reported as down those 15mins at least even though it may be back online after fencing withint a minute. We do set that property to 60s with Instance HA topology. Version-Release number of selected component (if applicable): How reproducible: always Steps to Reproduce: 1. Deploy composable roles with a node which has OS::TripleO::Services::PacemakerRemote 2. Reset the node Actual results: Node is being reported as offline more than 15 minutes even though It comes back online within a minute Expected results: Quicker recovery. Additional info:
Master merged. Linking the ocata backport here instead.
Verified on puppet-tripleo-6.3.0-12. The property is set to 60 seconds once topology with remote pacemaker nodes is used.
