[Lustre-discuss] Lustre Quota over Hard Limit

[Chan Ching Yu Patrick]

Hi,

I'm testing quota with latest maintenance release (Lustre 2.4.2).
I found that Lustre still allow the users to write the file over hard limit.

Let's see the example below. I've set 500MB soft limit and 530MB hard limit.
But I can write a 700MB file.

[patrick at client lustre]$ dd if=/dev/zero of=/lustre/file bs=1M count=700
700+0 records in
700+0 records out
734003200 bytes (734 MB) copied, 31.6627 s, 23.2 MB/s

[root at client lustre]# lfs quota -u patrick /lustre/
Disk quotas for user patrick (uid 500):
      Filesystem  kbytes   quota   limit   grace   files   quota

        /lustre/  716804* 500000  530000       -       1       0       
0       -
