Overview
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.
The Initial Quota Setup interface scans your server to confirm that it uses disk space quotas on the directories in which your cPanel users store their files. We recommend that you use quota support, and we enable it by default on new installation of cPanel & WHM. Without quota support, the server will not display disk space usage for users and it 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 databases 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 situation occurs because the kernel-enforced quota does not access cPanel settings.
- The backup process for an account near or over its quota may fail because the system cannot write necessary files (for example, a database lock file).
If you run a Virtuozzo® Virtual Private Server (VPS), read our Enable Quotas on a Virtuozzo VPS documentation.
For more information about quota-related issues, read our How to Fix Quotas documentation.
Quota setup
To perform the quota scan, click Proceed.
When you click Proceed, the system runs the /scripts/initquotas script. This script ignores /home directory mount points that use the following options:
nono autoloop
To troubleshoot this issue, check the /etc/fstab file for these options.
-
We enable quotas by default on new installations.
-
If you disable and then reenable quotas, servers that use the XFS® filesystem and run AlmaLinux OS 8, Rocky Linux 8, CentOS 7, CloudLinux 7 or 8, Red Hat® Enterprise Linux (RHEL) 7, or Ubuntu® require additional actions for quotas to function properly:
- WHM Interface Use WHMs Initial Quota Setup interface (WHM » Home » Server Configuration » Initial Quota Setup) to configure quotas.
- Command Line Run the
/scripts/fixquotasscript and then remount the file system. - Manually via the Command Line For instructions on how to perform the
/usr/local/cpanel/scripts/fixquotasscripts actions manually, read the Red Hat XFS and XFS Quota Management documentation.
-
If you have enabled the Reboot To Enable Filesystem Quotas Reminder and Filesystem Quotas Ready notifications, the system sends notifications when it is ready to reboot and when the quota scan finishes and quotas are functional.
-
CloudLinux 7 or 8 updates may break quotas. For this reason, after each CloudLinux 7 or 8 update, you must run the
/usr/local/cpanel/scripts/fixquotasscript and then remount the file system.
