Boot + Root + Raid + Lilo : Software Raid

mini−HOWTO

Michael Robinton, Michael@BizSystems.com

v1.04, July 20, 2000

This document provides a cookbook for setting up root raid using the 0.90 raidtools for bootable raid

mounted on root using standard LILO. Also covered is the conversion of a conventional disk to a raid1 or

raid5 mirror set without the loss of data on the original disk.

1. Introduction

1.1 Acknowledgements

The essence of the information I've put together here was originally provided by Harald Nordgård−Hansen

< hnh@bukharin.hiof.no > and posted to the raid mail list in a lilo.conf file with commentary by Martin Bene

< mb@sime.com > . Many thanks for your contribution. I've tried to put this information and the helpful work

of many others who contribute to the raid mail list and linux raid project into a COOKBOOK form,

including many examples from real systems so that bootable root raid is easy to set up and understand. One

section is devoted to the conversion of a standard single drive system to RAID. The key to the conversion, in

my humble opinion, is the understanding of bootable root raid.

1.2 Bugs

Yes, I'm sure there are some. If you'd be good enough to report them, I will correct the document. ;−)

2. What you need BEFORE YOU START

The packages you need and the documentation that answers the most common questions about setting up and

running raid are listed below. Please review them throughly.

2.1 Required Packages

You need to obtain the most recent versions of these packages.

6. Appendix B. − SCSI reference implementation RAID5

Boot + Root + Raid + Lilo : Software Raid mini−HOWTO

a linux kernel that supports raid, initrd

I used linux−2.2.14 from kernel.org

ftp://ftp.kernel.org/pub/linux/daemons/raid/alpha/ the most recent tools and patch that adds support

for modern raid1/4/5

I used http://people.redhat.com/mingo/raid−patches/

2.3 Documentation −− Recommended Reading

If you plan on using raid1/5 over raid0, please read:

/usr/src/linux/Documentation/initrd.txt

as well as the documentation and man pages that accompany the raidtools set.

and..... Software−RAID−HOWTO.html

2.4 RAID resources

Mailing lists can be joined at:

This one seems quiet: majordomo@nuclecu.unam.mx send a message to subscribe raiddev

send mail to: raiddev@nuclecu.unam.mx

Raid development: majordomo@vger.rutgers.edu send a message to subscribe linux−raid

send mail to: linux−raid@vger.rutgers.edu (this seems to be the most active list)

3. Bootable Raid

I'm not going to cover the fundamentals of setting up raid0/1/5 on Linux, that is covered in detail elsewhere.
