In order to use usual Linux disk quota (per-user) in VE, you should set "quotaugidlimit" parameter for it:
# vzctl set <veid> --quotaugidlimit 50 --save
# vzctl restart <veid>
# vzctl enter <veid>
entered into VE <veid>
VE# cat /etc/mtab 
/dev/simfs / reiserfs rw,usrquota,grpquota 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
tmpfs /dev tmpfs rw 0 0
devpts /dev/pts devpts rw 0 0
50 - means that 50 users inside VE can be limited by disk quota.

After that it should work.

Thanks,
Vasily.

This post is for information to the community.

Milind provided me an access to the node, and we found that there is in fact a problem with user quotas in VE on 2.6.9-based OpenVZ kernels.
The bug #632 (http://bugzilla.openvz.org/show_bug.cgi?id=632) was reported.

Thanks to Milind.

Swapnilm, I've send a PM to milind yesterday about possible workarounds. Here is the content of the message:

-----------
Hello, I've found the reason of the problem! Wink

Milind, you discoverd rather serious bug in 2.6.9-based kernels, thank you very much! It is not hard to fix it, I will do it today/tomorrow. I also will create a bug report and post a link to it to your initial post at support forum.

You can now remove admin/supp0rt login from your node.

After the patch will be sent some time will pass before the fresh kernel will be released. So, you have several opportunities:

1) Wait till the fresh kernel will be realeased
2) Compile kernel with the patch by you self
3) Just move to 028stab035 kernel, that has no such problem.

Thank you once again,
Vasily.
-----------

I think the path will be available today. Bug report link: http://bugzilla.openvz.org/show_bug.cgi?id=632

Vasily.

For me, I just updated when I received kernel update mail list announcement. Yes, quota is broken by updating.
2.6.9-023stab044.4-enterprise #1 SMP

So, I simply switched it back to
2.6.9-023stab043.2-enterprise #1 SMP
for now and wait for the fix.

Thanks.

Yes, you're right! The bug was introduced in 044 kernel: at this moment we moved to next RHEL update and getattr64() appeared there...

Thank you for the good workaround!
Vasily.

Hello Sachin,

You can download the "2.6.9-023stab043.2" kernel from the following URL:
==
http://download.openvz.org/kernel/branches/rhel4-2.6.9/023st ab043.2/ovzkernel-enterprise-2.6.9-023stab043.2.i686.rpm
==

Just install it using rpm -ivh --nodeps and boot the server using this kernel.

Let me know if you have any further questions.
