Description Rastislav Wagner 2020-05-11 08:46:30 UTC
MachineHealthCheck CR can be set to `external-baremetal` remediation strategy which means that the machine will reboot instead of reprovision. This is not recognized by Node's Overview page - Health checks item which always shows that the reprovision is pending.

MachineHealthCheck external-baremetal

1. Create MachineHealthCheck with YAML below which targets one machine
apiVersion: machine.openshift.io/v1beta1
kind: MachineHealthCheck
metadata:
  name: example
  namespace: openshift-machine-api
spec:
  selector:
    matchLabels:
      machine.openshift.io/cluster-api-cluster: qe-ui4-l99xm
      machine.openshift.io/cluster-api-machine-role: worker
      machine.openshift.io/cluster-api-machine-type: worker
      machine.openshift.io/cluster-api-machineset: qe-ui4-l99xm-w-c
  unhealthyConditions:
    - type: Ready
      status: Unknown
      timeout: 300s
    - type: Ready
      status: 'False'
      timeout: 300s
  maxUnhealthy: 40%

2. Goes to cloud provider console and stop the instances targeted in MHC
3. The node will become NotReady firstly, after 300s MHC will report accurate status, on Nodes Overview Status card, click on 'Health Checks' it will show `Warning alert:Reboot pending` instead of  `reprovisioning pending`
