由于备份已挂载，因此无法删除 SnapCenter 资源组

适用于

SnapCenter 服务器

问题

尝试删除 SnapCenter 中的资源组时，即使没有活动挂载，也会显示以下错误：

'Backup Deletion Failed: Backup <snapshot name> has mounts, cannot be deleted, unmount and retry again'

这是因为 SnapCenter 存储库（ NSM MySQL 数据库）包含引用备份挂载的陈旧条目。如果未使用 SnapCenter 从存储系统手动删除 SnapCenter 创建的克隆，则可能会导致此问题。
