Setup Quotas in Linux

1) Enter Single user Mode:

# init 1

2) Edit your /etc/fstab file

The /etc/fstab file lists all the partitions that need to be auto-mounted when the system boots. Edit and add “usrquota” option to the partition that you want to have quota enable

LABEL=/home       /home          ext3    defaults,usrquota  1 2

3) Remount your partition

# mount -o remount /home

4) Come out of single user mode

# Exit

5) Create quota file

The uppermost directory of the filesystem needs to have an aquota.user file (defines quotas by user) and an aquota.group file (defines quotas by group), or both.

# touch /home/aquota.user

# chmod 600 /home/aquota.user

5) Initialize the user quota

# quotacheck -vagum

6) Edit the quota for a user

# edquota -u sohail

The command will invoke the vi editor.

Disk quotas for user sohail (uid 501):
