How to Quota Users & Groups in Ubuntu

How to setup Disk Quotas in Ubuntu

5 Steps to Setup User and Group Disk Quota on UNIX / Linux

sudo apt-get install quota quotatool

Edit /etc/fstab and add usrquota and grpquota options to the mount point which contains the home directories. For me this was the root mount point, but it will depends on how you did your partitoning (it could be that you made a separate mount point for /home).

sudo gedit /etc/fstab

The entry should read something like:

# /dev/hda1 UUID=4ea80ca3-37b7-447e-831a-700a38627029 / ext3 defaults,errors=remount-ro,usrquota,grpquota 0 1

Finish setup with the following series of commands

sudo touch /quota.user /quota.group
sudo touch /aquota.user /aquota.group

sudo chmod 600 /quota.*
sudo chmod 600 /aquota.*

sudo mount -o remount /

sudo quotacheck -avugm

sudo quotaon -avug

edquota myuser
