Hello,
I am new on this forum (and OpenVZ) and I am having some trouble setting up openvz user/group quotas inside VE's.
I am trying openvz on 2 servers. On the first one, quotas worked fine (same kernel, but first one is i386 and second one is Core2Duo :
Linux server 2.6.22-ovz005.1 #1 SMP Thu Nov 15 15:35:00 MSK 2007 x86_64 x86_64 x86_64 GNU/Linux
- usrquota/grpquota are not set on the HN partitions. Is that correct?
# vzctl set 151 --quotaugidlimit 100 --save
Configure meminfo: 35000
Setting quota ugidlimit: 100
Saved parameters for VE 151
## INSIDE THE VE:
# vzctl enter 151
entered into VE 151

/vz/private is a separated partition dedicated for VE's. Can i have multiple VE's with user/group quotas on the same partition (/vz/private)?
Any help will be aprreciated.
Thanks a lot.

I think this is a bug. I was trying quota on 32bits VE's. The HN is 64bits. Now I installed a 64bit VE and quota worked. To make sure this have to do with the problem, i download both ubuntu precreated images (amd64 and i386 - on openvz.org). Quota works fine on amd64 and does not work on i386.
Here is the last lines of the strace output on a i386 VE:
open("/etc/mtab", O_RDONLY) = 3
fstat64(3, {st_mode=S_IFREG|0644, st_size=258, ...}) = 0
