"In this series, I'm going to show you how to install and use the new Logical Volume Management support built-in to the Linux 2.4 kernel. If you've never used a form of LVM before, you're in for a treat; it's a wonderful technology. Before we actually get LVM up and running, I'm going to explain exactly what it is and how it works. Then, we'll be ready to test out LVM and get the most out of it."
"If you're like me, then your experience with UNIX and Linux began on a PC platform, rather than on large, commercial UNIX servers and workstations. On the basic PC, we've always had to deal with partitioning our hard drives. PC people are generally well-acquainted with tools such as fdisk, which are used to create and delete primary and extended partitions on hard disks. Hard disk partitioning is an annoying but accepted part of the process of getting an operating system up and running."
"Hard drive partitioning can be annoying because to do a good job you really need to accurately estimate how much space you'll need for each partition. If you make a poor estimation, your Linux system could possibly be crippled -- to fix the problem, it's possible that you might even need to perform a full system backup, wipe your hard drives clean, and then restore all your data to a new (and presumably better) partition layout. Ick! These are exactly the kinds of situations that sysadmins try their best to avoid in the first place."
