This makes me wonder about timeouts. Specifically OS/systemd timeouts. Say the node being shut down or rebooted holds a resource as a master, and it takes a while for the demote to complete, say 100 seconds (less than the demote timeout of 120s in this hypothetical scenario). Will the OS/systemd wait until pacemaker exits cleanly on a regular CentOS or Debian? > Explicitly doing standby first would be useful mainly if you want to > manually check the results of the takeover before proceeding with the > reboot, and/or if you want the node to come back in standby mode next > time it joins. > > _______________________________________________ > Users mailing list: Users@clusterlabs.org > http://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 -- Ludovic _______________________________________________ Users mailing list: Users@clusterlabs.org http://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
