Ok. I modified my umount script to not show errors:

#!/bin/bash -x

umount /staj/vz/root/192003/mnt 2>/dev/null
vzquota off 10192003

Great. Thanks!

Yes I did initialized quota by:

# vzquota init 10192003 -p /staj/vz/private/192003.mnt -b 1000 -B 1500 
-i 100 -I 150 -e 0 -n 0

and I'm activating in mount script:

#!/bin/bash -x

vzquota on 10192003
mount -n --bind /staj/vz/private/192003.mnt /staj/vz/root/192003/mnt

It's working:

chlivek:~# vzctl enter 192003
entered into VE 192003
root at dns:/# echo "test" >/mnt/test
-bash: echo: write error: Disk quota exceeded

but df still show it as

 >> /dev2/root2           1.1T   46G 1020G   5% /mnt

which isn't very intuitive and for me as admin should be really better 
to be able hide total system capacity from my users :)

Any idea how to solve this?
