環境

  • ONTAP 9
  • FabricPool

説明

  • USEDdfFabricPool ボリュームに対してコマンドを実行する場合のサイズは、親のFabricPool アグリゲートとは異なります。
    • たとえば、次の出力では、アグリゲートの使用済みスペースは0GBです。

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.

ただし、ボリュームで使用済みスペースが 9GB と報告されます。

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.

  • これにより、9GBがすべて階層化されているにもかかわらず、クライアントはデバイス上の空き容量を報告しません。

[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]#
