Missing force drain for OpenShift nodes
Hi,
I suppose kubectl --force parameter is missing in the case of OpenShift cluster with "non standard" PODs. Not to be confused with node-restart --force parameter for restart without drain.
There should be internally kubectl drain <node> --force --ignore-daemonsets --delete-emptydir-data
--ignore-daemonsets and --delete-emptydir-data are also helpfull
kubectl node-restart -l node-role.kubernetes.io/worker=
