Description

Hi,

it doesn't look like lustre is enforcing group block quota. eg.

 > lfs quota -g oz011 /fred
Disk quotas for grp oz011 (gid 10206):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
          /fred 10893023318*      0 10737418240       -   57475       0 1000000       -
 > dd if=/tmp/urand100 of=/fred/oz011/blah bs=1M
1000+1 records in
1000+1 records out
1048738400 bytes (1.0 GB) copied, 0.995716 s, 1.1 GB/s
 > ls -lsh /fred/oz011/blah
688M -rw-r--r-- 1 user oz011 1001M Jul  1 21:42 /fred/oz011/blah
 > lfs quota -g oz011 /fred
Disk quotas for grp oz011 (gid 10206):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
          /fred 10894895294*      0 10737418240       -   57477       0 1000000       -

I can see old quota bugs that look similar, but none currently open.

all our directories are setgid. ie.

 > ls -ld /fred/oz011
drwxrws--- 17 root oz011 33280 Jul  1 21:42 /fred/oz011

server is 2.10.5 plus these

not all of which are in 2.10.x AFAIK (all but one are in 2.12?), so it'd unfortunately be quite a bit of work to update servers to 2.10.8.

clients are all stock 2.10.7

thanks

cheers,
