I recently had to migrate a CentOS 5 system from a single hard drive to a mirrored RAID configuration. Since I had set up the system with LVM originally I was able to do this (mostly) seamlessly while the machine was in production. This howto details the steps I took and the commands necessary to migrate the system.
