Fixed In Version: rhosp-director-images-13.0-20180425.2.el7ost
Doc Type: If docs needed, set a value
Doc Text:
When record-pending is true (which is the default as of 7.5), Pacemaker sees two notifications that notify actions completed: one when the action is initiated and another when it completes. This confuses the cluster and triggers a re-computation of the cluster state, which results in more notifications and more re-computations. The issue was resolved by configuring Pacemaker to only record completed clone-notify actions as successful, not those that are pending, which enables the cluster to complete the process of recovering or starting services.
