Fixed In Version: pacemaker-1.1.20-5.el7_7.1 Doc Type: Bug Fix
Doc Text:
Cause: Pacemaker implicitly ordered all stops needed on a Pacemaker Remote node before the stop of the node's Pacemaker Remote connection, including stops that were implied by fencing of the node. Also, Pacemaker scheduled actions on Pacemaker Remote nodes with a failed connection so that the actions could be done once the connection is recovered, even if the connection wasn't being recovered (for example, if the node was shutting down when the failure occurred). Consequence: If a Pacemaker Remote node needed to be fenced while it was in the process of shutting down, once the fencing completed pacemaker scheduled probes on the node. The probes fail because the connection is not actually active. Due to the failed probe, a stop is scheduled which also fails, leading to fencing of the node again, and the situation repeats itself indefinitely. Fix: Pacemaker Remote connection stops are no longer ordered after implied stops, and actions are not scheduled on Pacemaker Remote nodes when the connection is failed and not being started again. Result: A Pacemaker Remote node that needs to be fenced while it is in the process of shutting down is fenced once, without repeating indefinitely.
