Quotas

(1) Editing /etc/fstab

We need to add quota support to the file system.
Add usrquota to field four of the partition for which we want to set quotas.

    /dev/hda2      /home      ext3      defaults,usrquota      1 2

    /dev/hda2      /home      ext3      defaults,grpquota      1 2

    /dev/hda2      /home      ext3      defaults,usrquota,grpquota    1 2

This will allow the /home file system to allow disk quotas for all users' home directories under the /home directory.

The filesystem will have to be remounted in order for the change to take effect.

The following command will allow you to unmount and remount this directory:

[root@localhost etc]# mount -o remount /home

If this command does not work, then you will have to reboot.
Please be kind and let your users know that you are going to be doing this step. They may lose data if they are logged on at the time.
Remember that if you type init 1, you will be in single user mode. /home is not mounted in this mode.
