4.14. 创建隔离设备

完成以下步骤以创建隔离设备。

请注意,对于大多数默认配置,GCP 实例名称和 RHEL 主机名是一样的。

步骤

  1. 获取 GCP 实例名称。请注意,以下命令的输出还显示实例的内部 ID。

    # fence_gce --zone us-west1-b --project=rhel-ha-on-gcp -o list

    Example:

    [root@rhel81-node-01 ~]# fence_gce --zone us-west1-b --project=rhel-ha-testing-on-gcp -o list
    
    4435801234567893181,InstanceName-3
    4081901234567896811,InstanceName-1
    7173601234567893341,InstanceName-2
  2. 创建隔离设备。

    # pcs stonith create FenceDeviceName fence_gce zone=Region-Zone project=MyProject

验证

  • 验证隔离设备是否已启动。

    # pcs status

    例如:

    [root@rhel81-node-01 ~]# pcs status
    
    Cluster name: gcp-cluster
    Stack: corosync
    Current DC: rhel81-node-02 (version 1.1.18-11.el7_5.3-2b07d5c5a9) - partition with quorum
