Enabling Disk Quotas on File Systems

Disk quota types are enabled at mount by specifying a mount option.

Mount Option	Description

gquota	Enable group quotas and enforce usage limits.
pqnoenforce	Enable project quotas. Report usage, but don't enforce usage limits.

Mounting a File System With Quotas Enabled

Mount a file system from the command line with a quota type enabled.

If a file system doesn't have a system mount configured in /etc/fstab or the entry doesn't include a quota option, you can enable the quota option when you mount the file system from the command line.

1. Mount the file system from the command line using the -o <quotatype> option to enable the specified quota.
   For example, to enable user quotas, run:

   sudo mount -o uquota /dev/sdb1 /mnt

   Replace uquota with uqnoenforce to enable usage reporting without enforcing any limits.

Editing System Mounts to Use Quotas

Edit /etc/fstab to add quota options to a file system entry, to enable quotas when the file system is remounted.

1. Install the quota package on the system, if not already installed.

   sudo dnf install -y quota

2. Add the quota type options to the file system's /etc/fstab entry.

   For example, to add the uquota and gquota types, you can add:

   /dev/sdb1    /home     ext4    defaults,uquota,gquota   0 0

3. Remount the file system.

   sudo mount -o remount /home
