How to enable quotas on UEFI systems

Introduction

If you have attempted to enable quotas after following these guides with no success, then it likely means you have a system that utilizes UEFI firmware.

 

Procedure

  1. Run the following command to verify that the server is a UEFI System. 
    [ -d '/sys/firmware/efi/' ] && echo "UEFI System" || echo "Standard BIOS System"
  2. Create a backup of your EFI grub configuration. 
    cp -avx /boot/efi/EFI/centos/grub.cfg /boot/efi/EFI/centos/grub.cfg.$(date +%s)
  3. Rebuild the Grub configuration 
    grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg
  4. Confirm that quotas show as enabled in the new configuration using the following command. 
    grep quota /boot/efi/EFI/centos/grub.cfg

    If quotas are configured, the output of the above command should be similar to the following.

    linux /vmlinuz root=UUID=bc7453b1 ro rd.auto crashkernel=auto vga=normal nomodeset rdloaddriver=raid1 rootflags=uquota
    linux /vmlinu root=UUID=bc7453b1 ro rd.auto crashkernel=auto vga=normal nomodeset rdloaddriver=raid1 rootflags=uquota
  5. Reboot the server.
