适用场景

  • ONTAP 9
  • FabricPool

问题描述

  • USEDdf在FabricPool 卷上运行命令时的大小与父FabricPool 聚合不同。
    • 例如、在以下输出中、聚合已用空间为0GB:

cluster01::> df -A -g aggr2
Aggregate                total       used      avail capacity
aggr2                   2413GB       0GB     2413GB       0%
aggr2/.snapshot            0GB        0GB        0GB       0%
2 entries were displayed.

但是,卷会将已用空间报告为 9GB :

cluster01::> df -g siva
Filesystem               total       used      avail capacity  Mounted on                 Vserver
/vol/siva/                 9GB       9GB        0GB      99%  /siva                       svm1
/vol/siva/.snapshot        0GB        0GB        0GB       0%  /siva/.snapshot             svm1
2 entries were displayed.

  • 这样、即使所有9 GB空间都分层出来、客户端也会报告设备上没有剩余空间:

[nfs_client]# df -h /mydata
Filesystem         Size  Used Avail Use% Mounted on
svm1:/siva        9.5G  9.5G   12M 100% /mydata
[nfs_client]#
[nfs_client]# cp mydatafile.log /mydata
cp: error writing /mydata/mydatafile.log: No space left on device
cp: failed to extend /mydata/mydatafile.log: No space left on device
[nfs_client]#
