Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I'm migrating to a VMWare ESX server and now that I have the file share aspect of it set up, I copied all my data off the /storage share and removed the 3x500GB drives.
However, now my system can't boot since mdadm now labels the 2x20GB drives as /dev/md0 and /dev/md1, respectively.
My system is using lilo as a bootloader. I've even gone so far as to plug the 3x500GB drives back in but all I seem to get is initramfs prompt. I did get it to boot normally once but then the 3x500GB drives were /dev/md0 again and I could not execute /sbin/lilo to boot to md0 in the future (which would be my RAID 1 array after I power down and remove the 500GB drives again) because the 3x500GB drives are currently RAID 5 and lilo won't apply the changes.
I know all I need to do is change lilo.conf to reflect the correct md0 to boot to, however I have no way of running /sbin/lilo to apply the changes. Any suggestions?
Yeah, that's what it needed. Once I got a temporary CD-ROM installed in the server and booted to a rescue disk, it was a simple matter of editing lilo.conf to use /dev/md0, editing fstab, and then using chroot to run /sbin/lilo.
