1. Introduction

For unclear reasons this brand new release is codenamed the Taylor2 release.

New code names will appear as per industry standard guidelines to emphasize the state-of-the-art-ness of this document.

This document was written for two reasons, mainly because I got hold of 3 old SCSI disks to set up my Linux system on and I was pondering how best to utilise the inherent possibilities of parallelizing in a SCSI system. Secondly I hear there is a prize for people who write documents...

This is intended to be read in conjunction with the Linux Filesystem Structure Standard (FSSTND). It does not in any way replace it but tries to suggest where physically to place directories detailed in the FSSTND, in terms of drives, partitions, types, RAID, file system (fs), physical sizes and other parameters that should be considered and tuned in a Linux system, ranging from single home systems to large servers on the Internet.

The followup to FSSTND is called the Filesystem Hierarchy Standard (FHS) and covers more than Linux alone. FHS versions 2.0 and 2.1 have been released but there are still a few issues to be dealt with and even longer before this new standard will have an impact on actual distributions. FHS is not yet used in any distributions but Debian has announced they will use it in Debian 2.1 which is their next distribution.

It is also a good idea to read the Linux Installation guides thoroughly and if you are using a PC system, which I guess the majority still does, you can find much relevant and useful information in the FAQs for the newsgroup comp.sys.ibm.pc.hardware especially for storage media.

This is also a learning experience for myself and I hope I can start the ball rolling with this HOWTO and that it perhaps can evolve into a larger more detailed and hopefully even more correct HOWTO.

First of all we need a bit of legalese. Recent development shows it is quite important.

You are strongly recommended to take a backup of your system before major installation and backups at regular intervals.

1.3 News

This release features a major restructuring and more additions than I can list here especially on backup systems, hints and tips and even more on file system support. Also there is now a new appendix with a shell script that helps you characterise your system which is useful for debugging, especially when asking others for help. Also a section on troubleshooting has been added as well as a subsection on mount options.

This HOWTO now uses indexing and is based on SGMLtools version 1.0.5 and the old version will therefore not format this document properly.

Also quite new is a number of new translations available. Now a Chinese and also an Italian translation are under way.

On the development front people are concentrating their energy towards completing Linux 2.2 and until that is released there is not going to be much news on disk technology for Linux.

Also now the document is available in postscript both for US letter as well as European A4 formats.

The latest version number of this document can be gleaned from my plan entry if you finger my Nyx account.

Also, the latest version will be available on my web space on Nyx in a number of formats:

A European mirror of the Multi Disk HOWTO just went on line.

1.5 Translations

Special thanks go to nakano (at) apm.seikei.ac.jp for doing the Japanese translation, general contributions as well as contributing an example of a computer in an academic setting, which is included at the end of this document.

There are now many new translations available and special thanks go to the translators for the job and the input they have given:

Also DPT is acknowledged for sending me documentation on their controllers as well as permission to quote from the material. These quotes have been approved before appearing here and will be clearly labelled. No quotes as of yet but that is coming.

Not many still, so please read through this document, make a contribution and join the elite. If I have forgotten anyone, please let me know.

New in this version is an appendix with a few tables you can fill in for your system in order to simplify the design process.

Any comments or suggestions can be mailed to my mail address on Nyx: sgjoen@nyx.net.

So let's cut to the chase where swap and /tmp are racing along hard drive...
