适用场景

  • ONTAP 9
  • LUN
  • 卷

问题解答

  • 示例：
    • ESXi主机显示已用LUN约为3.9 TB
    • 卷已用空间仅为1.9 TB
Filesystem        kbytes     used    avail capacity  Mounted on
/vol/Lun_2/      53687091200 1880538864 24748859024     4%  /vol/Lun_2/
/vol/Lun_2/.snapshot      0      0      0     0%  /vol/Lun_2/.snapshot
  • 启用 卷效率时、可为存储卷节省更多空间。

Filesystem    used total-saved %total-saved deduplicated %deduplicated compressed  %compressed  vbn zero   %vbn zero
/vol/Lun_2/ 1880538864 2710438976      59%   2213897396       48%  496541580      11% 292142452       6%

  • 因此、客户端 显示LUN已用大小大于存储卷已用大小。
