столкнулся с проблемой включения квот.
Сделано вот что

server3:~# cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/sda2  /  ext3  grpquota,errors=remount-ro,usrquota,rw  0  1
/dev/sda1       /boot           ext2    defaults        0       2
/dev/sda6       /tmp            ext3    defaults        0       2
/dev/sda5       none            swap    sw              0       0

server3:~# lsmod | grep quo
quota_v2                8736  0
quota_v1                3552  0
vzdquota               32796  4 [permanent]
vzdev                   3624  4 vzethdev,vznetdev,vzdquota,vzmon

Далее

включаем квоты
