|
|
|
For unclear reasons this brand new release is codenamed
|
|
the <B>Taylor3</B> release.
|
|
<P>New code names will appear as per industry standard guidelines
|
|
to emphasize the state-of-the-art-ness of this document.
|
|
<P>
|
|
<P>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...
|
|
<P>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.
|
|
<P>
|
|
<P>The followup to FSSTND is called the Filesystem Hierarchy Standard (FHS)
|
|
and covers more than Linux alone. FHS versions 2.0, 2.1 and 2.2 have been
|
|
released but there are still a few issues to be dealt with. Many recent
|
|
distributions are now aiming for FHS compliance.
|
|
<P>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.
|
|
<P>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.
|
|
<P>
|
|
<P>First of all we need a bit of legalese. Recent development shows it is
|
|
quite important.

|
|
<P>This is a major upgrade featuring a new copyright statement that is
|
|
intended to be Debian compliant and allow for inclusion in their
|
|
distribution. A number of mistakes are corrected and new features
|
|
added such as descriptions of recent ATA features and more.

|
|
<P>On the development front people are concentrating their energy towards

|
completing Linux 2.4 and until that is released there is not going to
|
|
be much news on disk technology for Linux.
|

<P>

<P>Also now the document is available in postscript

both for US letter as well as European A4 formats.
