Before you can use the quota software, you must add an option to /etc/fstab for all the file systems where quotas must be supported. The next steps describe how:
1. Open /etc/fstab with an editor.
2. Select the column with options. Add the option usrquota if you want to apply a quota to users and grpquota to add a quota for groups. Repeat this procedure for all file systems where you want to use quotas.
3. Remount all the partitions where quotas have been applied (or restart your server). For example, to remount the root partition so that new settings are applied, use mount -o remount /.
