ONTAP 9.8P1

问题描述

  • AutoSupport 警报:HA组通知(卷严重空间不足)紧急
  • EMS日志中显示卷严重空间不足错误。

Thu Mar 30 02:20:06 [Node01: wafl_spcd_main: callhome.vol.space.crit:EMERGENCY]: Call home for VOLUME CRITICALLY OUT OF SPACE ERROR.
Thu Mar 30 02:20:06 [Node01: wafl_spcd_main: vol.phys.overalloc:EMERGENCY]: Aggregate node01_aggr0 is physically overallocated, using 109.0%% logical space and 104.4%% physical space.

  • df输出中的vol0空间利用率:

::> df

Filesystem        kbytes     used    avail capacity  Mounted on
/vol/vol0/       150705588   74897508   75808080    50%  /vol/vol0/
/vol/vol0/.snapshot   7931872   12733532      0    161%  /vol/vol0/.snapshot

  •  聚合空间利用率为100%全满。

::> df -A

Aggregate         kbytes     used    avail capacity  
node01_aggr0        167648972  167648972      0    100%  
node01_aggr0/.snapshot 8823628   1309204   7514424    15%  

  • 如果Delayed Frees大量统计聚合中的卷占用空间、则该值会随着时间的推移而增加、并且永远不会减少。 

::> volume show-footprint

Volume : vol0
 
    Feature                       Used    Used%
    --------------------------------    ----------------    -----
    Volume Data Footprint               70.2GB     42%
   Delayed Frees                   104GB     62%
 
    Total                       174GB     104%
