Why logical volume?

Greetings, I am preparing for my exams on Friday, I have successfully configured and unconfigured logical volumes, But what would you use them for ? The RHCE material is really the first time I have been exposed to this, and now that I can setup LVMs I don't see the point. I saw some post about them before, could someone give me some real examples of where you would use LVM? and why? (to what benefit) Thanks -- -- Chadley Wilson Production Line Supervisor Pinnacle Micro Manufacturers of Proline Computers ==================================== Exercise freedom, Use LINUX =====================================
