Description of problem: Upgrade failed due to unsupported scheduler predicate NoVolumeNodeConflict resulting in master controllers service cannot start Version-Release number of the following components: openshift-ansible-3.9.1-1.git.0.9862628.el7.noarch How reproducible: Always Steps to Reproduce: 1.

Minor cleanup for the scheduler upgrade, not expected to fix the problem, but related. https://github.com/openshift/openshift-ansible/pull/7333 Our belief is that ansible is skipping these task for no apparent reason.
PR updated: https://github.com/openshift/openshift-ansible/pull/7333 Cause was stale openshift.common.short_version set by openshift_facts being used inside the lookup plugin for scheduler config.
Fixed. openshift-ansible-3.9.2-1.git.0.1a855b3.el7.noarch # systemctl status atomic-openshift-master-controllers.service -l ● atomic-openshift-master-controllers.service - Atomic OpenShift Master Controllers Loaded: loaded (/usr/lib/systemd/system/atomic-openshift-master-controllers.service; enabled; vendor preset: disabled) Active: active (running) since Fri 2018-03-02 23:56:39 EST; 13min ago Docs: https://github.com/openshift/origin Main PID: 18475 (openshift)
