2. 要暂停机器健康检查，请将 cluster.x-k8s.io/paused="" 注解添加到 MachineHealthCheck 资源。运行以下命令:

   $ oc -n openshift-machine-api annotate mhc <mhc-name> cluster.x-k8s.io/paused=""

   注解的 MachineHealthCheck 资源类似以下 YAML 文件：

   apiVersion: machine.openshift.io/v1beta1
   kind: MachineHealthCheck
   metadata:
     name: example
     namespace: openshift-machine-api
     annotations:
       cluster.x-k8s.io/paused: ""
   spec:
     selector:
       matchLabels:
         role: worker
     unhealthyConditions:
     - type:    "Ready"
       status:  "Unknown"
       timeout: "300s"
     - type:    "Ready"
       status:  "False"
       timeout: "300s"
     maxUnhealthy: "40%"
   status:
     currentHealthy: 5
     expectedMachines: 5
