etcd instance on one of the CC's may become unresponsive after rolling upgrade to 1.3.1 due to failure to mount drbd partition. System will continue to function, but if the CC with functioning etcd instance goes offline, the openshift cluster will stop responding.
No immediate impact, but will cause HA failure if CC that is not affected goes offline while the etcd instance on remaining CC has hit this issue.
Rolling upgrade to 1.3.1 release from older software release.
Workaround is to re-install the openshift cluster by doing a "touch /var/omd/CLUSTER_REINSTALL" on the active CC.
