适用场景

VMware vSphere 6.7U3 

问题描述

NetApp ONTAP会将卷快照存储在卷中的.Snapshot目录中。 

  • 如果此.Snapshot目录可从ONTAP显示、则可以通过 vSphere Web Client或UI客户端中的存储视图进行浏览
  • 客户可以浏览.Snapshot目录以从NetApp卷快照还原所需的文件

启用了CBT (更改的块跟踪)后、vSphere 6.7U3中会显示问题描述。  此问题描述的症状包括:

  • 客户不能通过vSphere UI或使用vmkfl坦 工具-i进行克隆、从.Snapshot目录复制vmdk /-fl扁平.vmdk文件
  • 尝试从.Snapshot目录克隆或复制vmdk /-fl.vmdk文件时、遇到以下错误:

DISKLIB-LIB_CLONE   : Failed to clone : Invalid change tracker error code (5948)

或-

2019-10-11T16:44:55.855Z info hostd[2100574] [Originator@6876 sub=DiskLib opID=esxui-abcd-1234 user=root] DISKLIB-CTK : Could not open change tracking 
 file "/vmfs/volumes/abcd123-abcd123
/.snapshot/daily.2019-10-11_0010/VM/VM-ctk.vmdk": Change tracking invalid or disk in use.

  • 如果禁用了cbt且没有-ctk.vmdk文件、则复制操作成功。
