Cause

当虚拟机数据存储目录中存在孤立的临时快照描述符文件时，可能会出现此问题。这些快照描述符文件显示为 ####.-000001.vmdk、####.-0000001-sesparse.vmdk 和 ####.-000001-ctk.vmdk 。

Resolution

删除孤立的临时快照描述符文件的步骤记录在 VMware 知识库 80246 中。

https://kb.vmware.com/s/article/80246 此超链接会将您带往 Dell Technologies 之外的网站。  
  1. 浏览受影响的虚拟机数据存储区以识别临时描述符文件。名称可能显示为： 
    • ###-000001.vmdk
    • ###-000001-sesparse.vmdk
    • ####-000001-ctk.vmdk 
  2. 识别具有足够空间的文件夹以移动临时描述符文件并创建新文件夹
    • vmfs/volumes/VM_####_DATASTORE5/FOLDERNAME/
  3. 将临时描述符文件移动到新创建的文件夹
  4. 拍摄已成功创建的虚拟机和 validate 快照的快照。
  5. 使用“Delete All Snapshots”选项删除所有快照。
  6. 验证已删除的快照。
  7. 验证虚拟机数据存储区文件夹中没有描述符文件。
  8. 让计划的 vProxy 备份运行 。
