适用场景

  • ONTAP 9
  • 逻辑空间报告

问题描述

已为卷启用逻辑空间报告。这导致客户端看不到存储效率节省的空间，而存储效率将卷显示为接近全满。
 
从客户端上：
root@xxxx z3]# df -h /z3/*
Filesystem Size Used Avail Use% Mounted on
10.x.x.1:/data2 25T 24T 1.6T 94% /z3/56
10.x.x.2:/data2 25T 24T 1.6T 94% /z3/57
10..x.x.3:/data2 25T 24T 1.6T 94% /z3/58
10.x.x.4:/data2 25T 24T 1.6T 94% /z3/59
 
ONTAP 报告：
cluster::*>  df -h data2
Filesystem total used avail capacity Mounted on
/vol/data2/ 24TB 5TB 19TB 21% /data2
/vol/data2/.snapshot 4TB 0TB 4TB 0% /data2/.snapshot
