Description W. Trevor King 2021-02-25 20:55:29 UTC 
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.

Comment 10 W. Trevor King 2021-09-09 04:57:30 UTC 
This is not my component, so it's not my decision about whether or not to backport to 4.7.  Clearing my NEEDINFO.
Comment 11 jamo luhrsen 2021-09-09 17:57:10 UTC 
from what I can tell this did not get cherry-picked down to 4.7. I can handle that if it's needed, but I'll wait until it's asked for.
