Found some things:

oc describe clusteroperator/machine-config

oc delete pod node-ca-8566c -n openshift-image-registry
and all other node-* pods

oc get pods -n openshift-machine-config-operator 
oc logs -f -n openshift-machine-config-operator machine-config-controller-645db999c6-xjsqs -c machine-config-controller

oc adm drain node1.domain.tld --ignore-daemonsets --force --delete-emptydir-data
