"In my first LVM article, I explained the concepts behind LVM. Now it's time to put LVM into action. In this article, I'm going to set up LVM on the official Gentoo Linux web/cvs/email server, cvs.gentoo.org. Although cvs.gentoo.org has only one hard drive, LVM's flexibility still provides an incredible improvement over the standard static partitioning approach. I'll show you all the steps of the LVM conversion process, so that if you're interested you can perform a similar conversion on one of your machines."

"Before we begin, a warning. Because implementing LVM is a major change to the system (involving the creation of new partitions and other potentially hazardous actions) it's a really good idea to perform a full system backup before beginning this process. If you're not going to perform a backup, I hope you're using a test box with no important data on it :) I should mention that I didn't experience any problems while converting to LVM, but it's best to be prepared in case something goes wrong."

"That said, let's continue. Before starting the conversion process, I upgraded cvs.gentoo.org so that it was using the following packages. At the time I performed the LVM transition, these were the latest versions available (see Resources later in this article):"
* Linux kernel 2.4.1-ac19
* LVM 0.9.1_beta5
* reiserfs-utils 3.6.25"
