switchback failing—无法验证集群中复制单元的联机状态
适用场景
- MetroCluster
- 集群间
- 切回失败
- 集群之间的MTU不匹配
问题描述
发生意外切换后、切回失败。
MetroCluster 操作显示报告:
ClusterA::> metrocluster operation show
Operation: switchback
State: failed
Start Time: dd/mm/yyyy hh:mm:ss
End Time: dd/mm/yyyy hh:mm:ss
Errors: Failed to set up the node and cluster components for the switchback operation.
ClusterA (fatal): The MetroCluster DR operation was terminated because the online status of the replication units in the cluster could not be verified. Run the (privilege: advanced) "cluster ring show" command to display the status of the replication units. Try the MetroCluster DR operation again when each replication unit's "online" field shows either "master" or "secondary".
