示例定义了一个在区域中指定的 Alibaba Cloud 区域中运行的计算机器集，并创建通过 node- role.kubernetes.io/<role>: "" 标记的节点。 在本例中， 是基础架构 ID 标签，该标签基于您在置备集群时设定的集群 ID，而 <role> 则是要添加的节点标签。 $ oc get infrastructure cluster -o 1 machine.openshift.io/cluster-api-machine-role: <role> 2 machine.openshift.io/cluster-api-machine-type: <role> 3 name: -<role>- 4 namespace: openshift-machine-api spec: -<role>- 6 template: metadata: labels: machine.openshift.io/cluster-api-cluster: 7 machine.openshift.io/cluster-api-machine-role: <role> 8

从共享磁盘移到独立磁盘，以防止或解决性能问题。 先决条件 先决条件 MachineConfigPool 必须与 metadata.labels[machineconfiguration.openshift.io/role] 匹 配。这适用于控制器、worker 或自定义池。 节点的辅助存储设备（如 /dev/sdb ）必须与 sdb 匹配。在文件中的所有位置更改此引用。 注意 注意 这个过程不会将 root machineconfiguration.openshift.io/v1 kind: MachineConfig metadata: labels: machineconfiguration.openshift.io/role: master name: 98-var-lib-etcd spec: config: ignition: version: 3.2.0 systemd: machineconfiguration.openshift.io/v1 kind: MachineConfig metadata: labels: machineconfiguration.openshift.io/role: master name: 98-var-lib-etcd spec: config: ignition: version: 3.2.0 systemd:
