Description of problem:
Its the same issue as https://issues.redhat.com/browse/OCPBUGS-17199
Version-Release number of selected component (if applicable):
How reproducible:
always
Steps to Reproduce:
1.Create MHC for control plane
apiVersion: machine.openshift.io/v1beta1
kind: MachineHealthCheck
metadata:
name: control-plane-health
namespace: openshift-machine-api
spec:
maxUnhealthy: 1
selector:
matchLabels:
machine.openshift.io/cluster-api-machine-type: master
unhealthyConditions:
- status: "False"
timeout: 300s
type: Ready
- status: "Unknown"
timeout: 300s
type: Ready
2. oc create -f <above mhc.yaml>
oc get mhc
NAME MAXUNHEALTHY EXPECTEDMACHINES CURRENTHEALTHY
control-plane-health 1 3 3
machine-api-termination-handler 100% 3 3
3.Stop the kubelet service on the master node, new master get Running, the old one stuck in Deleting, many co degraded.
