From 77e8ec22a9cfa05c11a8654ce3a02c1bb3b4578f Mon Sep 17 00:00:00 2001 From: Steve Baker Date: Thu, 1 Oct 2015 10:17:29 +1300 Subject: Force stop a single node pacemaker on yum update Currently package updates won't occur on a single node non-HA pacemaker managed Controller because stopping the node loses the quorum of 1. This change gets the count of current nodes in the cluster and if the count is 1 then specify --force when doing a pcs cluster stop.
