红帽全球峰会5.4. 在集群中置备新主机时诊断重复的 MAC 地址
如果集群中现有裸机节点的 MAC 地址与您试图添加到集群的裸机主机的 MAC 地址匹配，Bare Metal Operator 将主机与现有节点关联。如果主机注册、检查、清理或其他 Ironic 步骤失败，Bare Metal Operator 会持续重试安装。失败的裸机主机会显示注册错误。
您可以通过检查在 openshift-machine-api 命名空间中运行的裸机主机来诊断重复的 MAC 地址。
先决条件
- 在裸机上安装 OpenShift Container Platform 集群。
-
安装 OpenShift Container Platform CLI
oc。 -
以具有
cluster-admin权限的用户身份登录。
流程
要确定置备失败的裸机主机是否具有与现有节点相同的 MAC 地址，请执行以下操作：
获取在
openshift-machine-api命名空间中运行的裸机主机：oc get bmh -n openshift-machine-api
$ oc get bmh -n openshift-machine-apiCopy to Clipboard Copied! Toggle word wrap Toggle overflow 输出示例
