问题描述
- 通过 API 创建 FlexClone 失败，并显示以下错误：
ErrorDetail(string='Server Error: STATUS=failed, REASON=Volume created successfully but not mounted. Reason: Failed to create junction record for volume <volume-name> on Vserver <vserver-name>. Reason: Node \"<node-name>\" on ring \"VLDB\" is offline. Check the health of the cluster using the \"cluster show\" command. For further assistance, contact technical support.

- 查看自动支持(ASUP)日志时，将记录以下错误：

- 管理网关守护程序(MGWD)在大约(<20)秒内脱机并重新联机
注： MGWD 提供哪些服务？
Mgwd 是在集群中每个节点上运行的进程，该进程：
- 提供 Clustershell 命令行访问
- 处理对节点的外部 ZAPI 和 REST API 调用
- 管理对 Systemshell 的身份验证访问
- 核心文件不会通过从集群外壳运行此命令自动生成和确认：
system node coredump show
