Quota is used for limiting the disk usage for users or groups.
###To verify that the quota is enabled in the kernel###
#grep CONFIG_QUOTA /boot/config-`uname -r`

Create user :
#useradd rajat
#passwd latar
Edit /etc/fstab :
From :
/dev/sda5 /home ext3 defaults 1 2
To :
/dev/sda5 /home ext3 defaults,usrquota,grpquota 1 2
Remount the disk (make sure it’s not in use) :
#mount -o remount /home
Check if usrquota and grpquota are enabled :
#mount | grep /home
Create quota files :
#quotacheck -cvug /home
This creates /home/aquota.user and /home/aquota.group
Check quota :
#quotacheck -avug
Enable quota for user1 :
#edquota user1
Edit soft and hard limits (1000 = 1 MB) or inode values.
Check the quota for user1 :
#quota user1
Enable quota :
#quotaon -avug
In addition :
Through a cron, run everynight when the filesystem is not used :
#quotaoff -avug && quotacheck -avug && quotaon --avug
Get quota stats :
#repquota -a
#useradd rajat
#passwd latar
