How to enable quotas on servers using the XFS filesystem

Introduction

To enable quotas on a server using XFS, you can use the WHM: Initial Quota Setup Feature. The feature will run the 'intiquotas' script.

There is a requirement of an extra step of needing to reboot the server when it completes for quotas to be functional.

Procedure

1. Log in to the server as 'root' using SSH, or use the WHM: Terminal Feature.

2. Use the following command to verify your filesystems are mounted using XFS.

Filesystem as seen in /etc/fstab:

# grep xfs /etc/fstab
/dev/mapper/centos_whm1-root / xfs defaults,uquota 0 0
UUID=fe712bf1-6f9f-4f69-950f-add2a660dfd4 /boot xfs defaults 0 0
/dev/mapper/centos_whm1-home /home xfs defaults 0 0

Filesystems that are currently enabled:

# mount | grep xfs | grep -v virtfs
/dev/mapper/centos_whm1-root on / type xfs (rw,relatime,attr2,inode64,usrquota)
/dev/sda2 on /boot type xfs (rw,relatime,attr2,inode64,noquota)
/dev/mapper/centos_whm1-home on /home type xfs (rw,relatime,attr2,inode64,noquota)
/dev/mapper/centos_whm1-root on /var/tmp type xfs (rw,relatime,attr2,inode64,usrquota)

3. Once you verify your XFS filesystem is mounted, log into the WHM interface, and navigate to the following location:

WHM: Home -> Server Configuration -> Initial Quota Setup

4. View the page, and click 'Proceed'. *Note the warning about rebooting the server afterward*

5. Depending on how big the filesystems are, it may take some time for it to complete. But, once complete, it should look similar to this:

6. Once the quotas are enabled, use the WHM interface to reboot the server.

WHM: Home »System Reboot »Graceful Server Reboot

If you wish to skip Step 3, 4, 5, & 6, and run the commands needed manually, you can use the following

Run commands as 'root' on the command line:

/scripts/initquotas
/scripts/fixquotas
reboot
