适用场景

  • ONTAP 9
  • 精简配置卷

问题描述

  • 通常、卷的可用大小=  总 大小-已用大小、但是、对于精简配置卷、有时 报告的可用大小小于(总 大小-已用大小)的值。

cluster1::> df -h
Filesystem         total     used    avail   capacity Mounted on          Vserver
/vol/vol1/         972GB     200GB    524GB    20%       /vol1                svm1
/vol/vol1/.snapshot    0       0      0      0%     /vol/vol1/.snapshot     svm1  


cluster1::> df -h
Filesystem               total       used      avail    capacity  Mounted on                 Vserver
/vol/vol2/               825GB       42GB      0       5%       /vol/vol2                  svm1
/vol/vol2/.snapshot      0           0         0        0%        /vol/vol2/.snapshot        svm1      

  • 如果容量小于5%、则会显示以下事件。

[XXXX: wafl_spcd_main: monitor.volume.nearlyFull:error]: Volume XXXX is nearly full (using or reserving 95%% of space and 0%% of inodes).

  • 一旦卷的可用大小为0、就会发生访问拒绝。
