[ClusterLabs] STONITH interrupting pacemaker yum upgrades
Hi, I'm having trouble updating pacemaker on a small 3 node cluster. All nodes are running Centos 7, and I'm upgrading via a simple `yum upgrade`. Whenever I attempt to do this the node is fenced when yum attempts to clean up the old pacemaker package - restarted by STONITH in this case. Updating pacemaker is a common requirement, is there a recommended process to upgrade pacemaker without taking out the node, or should I remove the node before upgrading HA components?

In most cases, you should stop the cluster on a node before upgrading it
("pcs cluster stop" on Fedora/RHEL/CentOS). The document below describes
various approaches to updates:

This reminds me of a new feature that I'll post about separately ...
