Backup anything in the / partition that you want to keep. This includes config files, customizations, mail, web site data, etc. If you want to do a full backup/restore you may be able to do that by using tar and creating a file in /home of all the data in / (but not including /home and space permitting) 2. Boot from some live distro such as knoppix, and use qtparted to resize sda2 smaller by the amount you want. Then remove and recreate sda3 to fill the new larger space. 3. Reinstall, or restore the data for sda3. These 3 steps should handle what you are asking for
