Enable Quotas on a Virtuozzo VPS
Valid for versions 82 through the latest version
Last modified: August 9, 2022
Your server’s quotas will not function unless you enable both first- and second-level Virtuozzo® quotas.
These commands only work if you run cPanel & WHM on a Virtuozzo VPS.
If you run cPanel & WHM on a Virtuozzo Virtual Private Server (VPS), and you disable quotas, you must perform extra steps to reenable quotas.
Virtuozzo disk quotas
Virtuozzo servers use the following types of disk quotas:
Per-container, or first-level, quotas allow system administrators to limit the amount of disk space and the number of inodes that a Virtual Server (Container) can use. This helps to control the sizes of VPS file systems.
Per-user and per-group, or second-level, quotas allow the Virtual Server administrator to limit the amount of disk space and the number of inodes that users and groups in the VPS can use.
If your Virtuozzo server uses the Ploop storage format, disk use calculations may appear large. This is because the filesystem reports its disk usage from within the container and not at the node level.
The Container (VPS) start-up process enables first-level quotas.
To determine whether first-level quotas are already enabled, run the following command, where
Container_ID represents the container ID of the container that you wish to check:
vzquota show Container_ID
QUOTAUGIDLIMIT parameter in the Container configuration file controls second-level disk quotas. This parameter defaults to
0, which disables per-user and per-group quotas.
To view the parameter and its value, run the following command:
grep -i QUOTAUGIDLIMIT /etc/sysconfig/vz-scripts/CT_ID.conf
If this command returns an empty result, or a result of
0, this environment does not support second-level quotas.
A non-zero value in the
QUOTAUGIDLIMITparameter limits the number of file owners to the number that you assign to this parameter.
The number of file owners includes Linux system users and groups that are within the Container. You can create additional VPS users beyond this number, but these extra users cannot own files.
Enable second-level quotas
To enable second-level quotas for the Container, perform the following steps:
QUOTAUGIDLIMITparameter to a value that is greater than zero.
Run the following command to enable second-level quotas, where
Container_IDrepresents the container ID of the container that you wish enable second-level quotas on.
vzquota on Container_ID -s 1
Restart the Container.
