Issue

The maximum allowable inodes on a volume could be equal to, or slightly slower than the specified value (maxfiles). 
  • Maximum allowable inodes equals to the specified value (maxfiles). 

cluster1::> volume modify -vserver svm1_cluster1 -volume vol_inode -files 80000
Volume modify successful on volume vol_inode of Vserver svm1_cluster1.

cluster1::> volume show -volume vol_inode -fields files
vserver       volume    files
------------- --------- -----
svm1_cluster1 vol_inode 80000

cluster1::> df -i vol_inode
Filesystem               iused      ifree  %iused  Mounted on                 Vserver
/vol/vol_inode/             96      79904      0%  ---                        svm1_cluster1
 

Notes:

  • Maximum allowable inodes from df -i equals to the sum of iused and ifree.
  • In this case, the maximum allowable inodes from both volume show and df -i are equal to the value of 80000 specified in volume modify. 

 

  • Maximum allowable inodes is slightly smaller than the specified value

cluster1::> volume modify -vserver svm1_cluster1 -volume vol_inode -files 110000
Volume modify successful on volume vol_inode of Vserver svm1_cluster1.

cluster1::> volume show -volume vol_inode -fields files
vserver       volume    files
------------- --------- ------
svm1_cluster1 vol_inode 109991

cluster1::> df -i vol_inode
Filesystem               iused      ifree  %iused  Mounted on                 Vserver
/vol/vol_inode/             96     109895      0%  ---                        svm1_cluster1
 

Notes:

  • Maxfiles is set to 110,000 in this case.
  • Maximum allowable inodes shown in volume show is 109991, which is 9 less than the specified value.
  • Maximum allowable inodes shown in df -i is also 96 + 109895 = 109991.
