For cPanel & WHM version 11.50

(Home >> Server Configuration >> Initial Quota Setup)



Servers that run CentOS 7 with the XFS® filesystem require additional actions for quotas to function properly:

  1. After you enable quotas in WHM's Initial Setup Wizard interface, and the system performs the necessary configuration changes, a button appears in the top right corner of the WHM interface. 
  2. You must click this button to reboot the system.
  3. After the system reboots, a quota scan runs in the background to complete the process.

If you have enabled Quota System Administration notifications, the system sends notifications both when it is ready to reboot, and when the quotas are functional after the scan finishes.

The Initial Quota Setup interface scans your server to confirm that it uses disk quotas on the directories in which your cPanel users store their files.

We recommend that you use quota support. Without quota support, users appear to use no disk space and the server will not enforce quota limits.


  • Quotas do not limit updates that a user can make to a MySQL, MariaDB, or PostgreSQL database.
  • Quotas that include database space only affect cPanel-related functions.
  • Processes that the system runs, such as PHP scripts that create files, can create user-owned files until the number of files reaches the quota. This is because the kernel-enforced quota is not aware of cPanel settings.


If you run a Virtuozzo® Virtual Private Server (VPS), read our Enable Quotas on a Virtuozzo® VPS documentation.

Quota setup

To perform the quota scan, click Proceed.


This feature requires kernel support for quotas on your server. If your server uses a custom kernel that does not include quota support, the initial quota setup process may result in an unbootable system.
