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

This is also possible via this option:

DISKSPACE="unlimited"

Filesystem dependency

If your host filesystem is not ext2/3/4 (like XFS) the disk quotas will not work inside containers.

Note: ext4 is also fully supported in 2.6.32 kernels and in RHEL5-based kernels since 028stab066.7
