问题描述

  • 在 vSphere 客户端数据存储视图中,某些虚拟机的"Used capacity"存在差异。
  • 这三个虚拟机的磁盘是厚配置的(Lazy Zeroed)。
  • 文件资源管理器中显示的用法大致相同(147 GB)。
  • 但是,当查看 vSphere 客户端中的数据存储时, Used capacity 显示为仅显示 XXX14 且值异常小。
  • vSphere Client 显示
XXX14: 128.71GB used
XXX13: 352.74GB used
XXX15: 352.32GB used
  • 在 ONTAP 节点 shell 中使用 du 的物理用量(针对每个 VM),XXX14-flat.vmdk 文件本身小于其他两个。
XXX13-flat.vmdk:377004328
XXX15-flat.vmdk:374874164
XXX14-flat.vmdk:135915844
