19.9 Using Quota Groups

Note

The quota groups feature requires that you boot the system using UEK R3.

# btrfs quota enable volume

# btrfs qgroup limit size /volume/subvolume

# btrfs qgroup limit 1g /myvol/subvol1
# btrfs qgroup limit 512m /myvol/subvol2

To find out the quota usage for a subvolume, use the btrfs qgroup show path command:
