Description of problem: Grafana deployment failed during 4.2->4.3 upgrade * Cluster operator monitoring is reporting a failure: Failed to rollout the stack. Error: running task Updating Grafana failed: reconciling Grafana Deployment failed: updating deployment object failed: waiting for DeploymentRollout of grafana: deployment grafana is not ready. status: (replicas: 1, updated: 1, ready: 0, unavailable: 1) in: https://prow.svc.ci.openshift.org/view/gcs/origin-ci-test/logs/release-openshift-origin-installer-e2e-aws-upgrade/10313
My guess: OVS was restarted during the setup and somehow we have half-set-up pods. Not entirely sure how that could have happened.
There's at least one occurrence of this here so i'm bumping this back up to medium so that we can take another look at it. https://search.svc.ci.openshift.org/?search=reconciling+Grafana+Deployment+failed%3A&maxAge=336h&context=2&type=build-log
