This bug was initially created as a copy of Bug #1933173 I am copying this bug because it also applies to OVN It's currently maxUnavailable: 1, but we want maxUnavailable: 10%, so we scale better on clusters with large node-counts. Checking a recent 4.8 CI release: $ curl -s https://gcsweb-ci.apps.ci.l2s4.p1.openshiftapps.com/gcs/origin-ci-test/logs/release-openshift-origin-installer-e2e-gcp-4.8/1364411741282242560/artifacts/e2e-gcp/daemonsets.json | jq -r '.items[] | select(.spec.template.spec.nodeSelector["node-role.kubernetes.io/master"] != "" and .spec.updateStrategy.rollingUpdate.maxUnavailable != "10%") | .metadata.namespace + " " + .metadata.name + " " + (.spec.template.spec.nodeSelector | tostring) + " " + (.spec.updateStrategy | tostring)' ... openshift-sdn sdn {"kubernetes.io/os":"linux"} {"rollingUpdate":{"maxUnavailable":1},"type":"RollingUpdate"} Like bug 1933159, but different DaemonSet.
