适用场景

  • ONTAP 9
  • Red Hat Enterprise Linux 服务器
  • XFS

问题描述

  • 在RHEL服务器上挂载克隆的LUN时收到以下错误:

# mount /dev/mapper/testXX-testXX/testXX_clone
mount: /testXX_clone: wrong fs type, bad option, bad superblock on /dev/mapper/testXX-testXX, missing codepage or helper program, or other error.

 

  • XFS文件系统具有UUID、UUID是文件系统的唯一标识符。
  • 如果克隆或复制了文件系统的后备存储、则两个文件系统上包含文件系统UUID信息的元数据将完全相同。
  • LVM快照将与原始文件系统具有相同的UUID。
