适用于

  • ONTAP 9.9.1 及更高版本
  • Qtree
  • NFS 配额

问题

具有默认或磁盘配额的 qtree 上的客户端 df 不显示 FlexVol/FlexGroup 的配置大小:
 
示例:
  • FlexGroup 配置大小为 685TB:
[root@host ~]# df -h /mnt/volume
Filesystem              Size  Used Avail Use% Mounted on
Cluster01-svm1:/vol/vol1       685T  169T  516T  25% /mnt/volume
 
  • FlexGroup 内的 qtree 显示总大小为 516TB:
[root@host ~]# df -h /mnt/volume/qtree1
Filesystem              Size  Used Avail Use% Mounted on
Cluster01-svm1:/vol/vol1       516T   0  516T  0% /mnt/volume
 
  • 同一个 FlexGroup 中的另一个 qtree 显示总大小为 564TB:
[root@host ~]# df -h /mnt/volume/qtree2
Filesystem              Size  Used Avail Use% Mounted on
Cluster01-svm1:/vol/vol1       564T  49T  516T  9% /mnt/volume
