"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
* Linux kernel 2.4.1-ac19
* LVM 0.9.1_beta5
* reiserfs-utils 3.6.25"
