适用场景

  • ONTAP 9
  • 卷效率(重复数据删除)
  • 已启用逻辑空间报告

问题描述

  • 如果在节省了大量效率(逻辑数据)的卷上启用了逻辑空间报告、则会错误地报告卷的大小。
  • 逻辑空间报告关闭:
::> df -h vol1
Filesystem          total  used   avail  capacity   Mounted on       Vserver
/vol/vol1/          972MB  431MB  540MB  44%        /vol1            vs0
/vol/vol1/.snapshot 51MB   0B     51MB   0%         /vol1/.snapshot  vs0
  • 卷具有相当多的节省量/逻辑数据:
::*> df -s -h vol1
Filesystem    used    total-saved
/vol/vol1/    448MB   581MB
  • 启用逻辑空间报告后、客户端系统会显示以下内容:
bash-4.2 /mnt/vol1 > df -h .
Filesystem    Size    Used   Avail   Use%   Mounted on
/vol1         1.6G    1.0G   540M    66%    /mnt/vol1
