Disk quota

Basic disk quota management:

To set disk space, run the following commands:

  vzctl set CTID --diskspace $SoftLimit$:$HardLimit$ --save

Example:

[host-node]# vzctl set 101 --diskspace 6G:7G --save

You could verify the space available with this command (ie : CTID =101)

[host-node]# vzctl exec 101 df -h

If you want remove disk quota:

DISK_QUOTA=no

Filesystem dependency

If your host filesystem is not ext2/3 (like XFS) the disk quotas will not work inside containers. Starting with 2.6.32, OpenVZ also suports ext4 i.e. one can limit per VE diskspace usage as well as per user diskspace usage.
