a further observation:
a user deleted a ~100MB file:
before.
[root at wnfg001 lustre]# lfs quota -u sandhoff /lustre
Disk quotas for user sandhoff (uid 11206):
Filesystem kbytes quota limit grace files quota limit
grace
/lustre 811480188 1811480200 2811480200 - 61077 0
0 -
after:
[root at wnfg001 lustre]# lfs quota -u sandhoff /lustre
Disk quotas for user sandhoff (uid 11206):
Filesystem kbytes quota limit grace files quota limit
grace
/lustre 811480188 1811480200 2811480200 - 61076 0
0 -
[root at wnfg001 lustre]#
so #files decreased by 1, but not the #kbytes.
Furthermore, the lfs quota command is pretty slow:
[root at wnfg001 lustre]# time lfs quota -u sandhoff /lustre
Disk quotas for user sandhoff (uid 11206):
Filesystem kbytes quota limit grace files quota limit
grace
/lustre 811480188 1811480200 2811480200 - 61076 0
0 -
real 0m2.441s
user 0m0.001s
sys 0m0.004s
[root at wnfg001 lustre]#
although the system is not overloaded.
Couldn't find anything useful in dmesg:
