[Lustre-discuss] lustre quota problems

[Wojciech Turek]

Hi,

I followed your scenario on my test lustre 1.6.3 installation

1) set quota limit
lfs setquota -u test 0 512000 0 0 /home

2) create files
for i in 1 2 3 4 ; do dd if=/dev/zero of=dummy.$i bs=102400K count=1  
& done
files are created
  lfs quota -u test /home
Disk quotas for user test (uid 627):
      Filesystem  kbytes   quota   limit   grace   files   quota    
limit   grace
           /home  409620       0  512000               6       0       0
ddn_home-MDT0000_UUID
                       4       0  102400               6       0       0
ddn_home-OST0000_UUID
                  102404*      0  102400
ddn_home-OST0001_UUID
                  102404*      0  102400
ddn_home-OST0002_UUID
                  102404*      0  102400
ddn_home-OST0003_UUID
                  102404*      0  102400

3) delete files
  rm -rf dummy.*
lfs quota -u test /home
Disk quotas for user test (uid 627):
      Filesystem  kbytes   quota   limit   grace   files   quota

           /home       4       0  512000               2       0       0
ddn_home-MDT0000_UUID
                       4       0  102400               2       0       0
ddn_home-OST0000_UUID
                       0       0  102400
ddn_home-OST0001_UUID
                       0       0  102400
ddn_home-OST0002_UUID
                       0       0  102400
ddn_home-OST0003_UUID
                       0       0  102400

4) create files again
for i in 1 2 3 4 ; do dd if=/dev/zero of=dummy.$i bs=102400K count=1  
& done

ls -l
total 409616
-rw-rw-r--  1 test test 104857600 Jan  9 16:28 dummy.1
-rw-rw-r--  1 test test 104857600 Jan  9 16:28 dummy.2

-rw-rw-r--  1 test test 104857600 Jan  9 16:28 dummy.4

lfs quota -u test /home

                       4       0  102400               6       0       0

                  102404*      0  102400

                  102404*      0  102400
ddn_home-OST0003_UUID
                  102404*      0  102400

As you see I couldn't reproduce your scenarios but I think source of  
my problem is similar to yours. I created bugzilla ticket for my problem
https://bugzilla.lustre.org/show_bug.cgi?id=14619

cheers
