[lustre-discuss] space usage is not limited when using project quota

[Moreno Diego (ID SIS)]

Hi Zhang Di,

Hope it’s not too late to jump into this one 😊 You’re only providing the quota settings on MDT0 but did you also enable project quotas on the OSTs?

oss1$> lctl get_param osd-*.*.quota_slave.info | grep space
space acct:     ugp
space acct:     ugp
space acct:     ugp
space acct:     ugp
space acct:     ugp
space acct:     ugp
space acct:     ugp
space acct:     ugp

Regards,

Diego

Subject: [lustre-discuss] space usage is not limited when using project quota

Hi,
I’m trying to use lustre’s project quota feature, my quota configuration is:

[root at mds1 dc2-user]# lctl get_param osd-*.*.quota_slave.info<http://quota_slave.info/>
osd-ldiskfs.lustrefs-MDT0000.quota_slave.info<http://osd-ldiskfs.lustrefs-mdt0000.quota_slave.info/>=
target name:    lustrefs-MDT0000
pool ID:        0
type:           md
quota enabled:  ugp
conn to master: setup
space acct:     ugp
user uptodate:  glb[1],slv[1],reint[0]
group uptodate: glb[1],slv[1],reint[0]
project uptodate: glb[1],slv[1],reint[0]

And have enable filesystem project feature:

[root at mds1 dc2-user]# dumpe2fs -h /dev/vdc | grep 'Filesystem features'
dumpe2fs 1.42.13.wc6 (05-Feb-2017)
Filesystem features:      has_journal ext_attr resize_inode dir_index filetype mmp flex_bg dirdata sparse_super large_file huge_file uninit_bg dir_nlink quota project

Then I set quota on client:
[root at client2 test]# lfs quota -p 123 /mnt/test
Disk quotas for prj 123 (pid 123):
   Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
    /mnt/test       4   10240   10240       -       1   10000   10000       -

Although the hard limit is 10M, the lustre quota don’t limit file size I write:

dd if=/dev/zero of=hello bs=30M count=1

[root at client2 test]# lsattr -p
  123 -----------------P ./hello

[root at client2 test]# lfs quota -p 123 /mnt/test
Disk quotas for prj 123 (pid 123):
   Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
    /mnt/test   28676*  10240   10240       -       2   10000   10000       -

My lustre version is 2.10.3, so, Does it a lustre quota's bug ?
Thank you very much.
