<b><font face="ARIAL NARROW,HELVETICA">Installing from the SGI
XFS for Red Hat 7.1 Installer</font></b></h2>


<P>
The SGI XFS Filesystem 1.0 Release for Red Hat 7.1 Installer is
available as an 
<A HREF="ftp://oss.sgi.com/projects/xfs/download/Release-1.0/iso">ISO
image</A>, from which you can create a bootable 
installer CD-ROM.  This CD-ROM, together
with the original Red Hat 7.1 installation media, will allow you to
install an XFS-capable system based on Red Hat 7.1.
</P>

<P>
The SGI installer is a modified version of the standard Red Hat installer,
so answers to most questions about the install can be found in
<A HREF="http://www.redhat.com/support/manuals/RHL-7.1-Manual/install-guide/">
the Red Hat 7.1 Installation Guide</A>.
</P>

<p>
A list of caveats you should take into account when installing
SGI XFS Linux Release 1.0 with the Red Hat 7.1 Installer is provided
<A HREF="#_installcavs">below</A>
</p>
<P>
In general, you can either boot directly from the installer, or create a
boot floppy from the appropriate disk image in the <tt>images/</tt> directory
on the CD.
The basic install methods default to XFS on all filesystems.  You may
select the "Custom" install method for additional control of filesystem
types.
</P>

<P>
Upgrades from previous Red Hat Linux versions are supported, as are
upgrades from previous XFS/Red Hat Linux installations.  Note, however,
that an upgrade install will <b>not</b> convert any existing ext2 filesystems
to xfs.
</P>

<h3>
<A NAME="_installcavs">Installer caveats</A>
</h3>

<p>
Following is a list of caveats you must consider when
installing SGI XFS Linux Release 1.0 with the Red Hat 7.1
Installer.
These caveats apply only to the Installer itself.  Please
see
<a href="1.0_caveats.html">XFS for Linux Release 1.0 Caveats</a>
for XFS Filesystem caveats.
</p>


<ul>
<li>
<P>
RAID installations have not been tested.
</li>
</ul>
</P>


<p>
<ul>
<li>
When using this installer on a system with data, make
sure that full backups are performed before attempting
the install.
</li>
</ul>

<p>
<ul>
<li>
Kickstart installations work, but are not  
thoroughly tested.  Add "--fs xfs" to the "part" command to 
create XFS partitions 
</li>
</ul>

<p>
<ul>
<li>
<tt>devfs</tt> is enabled in the installed kernels.  Please see
<a href="http://www.atnf.csiro.au/~rgooch/linux/docs/devfs.html">the
devfs FAQ</a>.
One common problem encountered is when a user tries to run
the <tt>startx</tt> command and gets
<blockquote><tt>
Authentication failed - cannot start X server.<br>
Perhaps you do not have console ownership?</tt></blockquote>
To fix this problem, edit <tt>/etc/security/console.perms</tt>:<p>
Change:<br>
<blockquote><tt>
# file classes -- these are regular expressions<br>
<console>=tty[0-9][0-9]* :[0-9]\.[0-9] :[0-9]<br>
</tt></blockquote>
<p>
To:<br>
<blockquote><tt>
# file classes -- these are regular expressions<br>
<console>=tty[0-9][0-9]* vc\/[0-9][0-9]* :[0-9]\.[0-9] :[0-9]<br>
</tt></blockquote>
<p>You may also need to reconfigure GPM and XFree86 to
use the correct mouse device.
</li>
</ul>

<p>
<ul>
<li>
<A NAME="_RPMwarn">
Do not upgrade your kernel to subsequent Red Hat RPMs, or
you will be unable to access your XFS partitions.
SGI will release XFS-capable kernel RPMs from time to time.
</li>
</ul>

<p>
<ul>
<li>
Please report any bugs found in the installer to 
<a href="mailto:linux-xfs@oss.sgi.com">linux-xfs@oss.sgi.com</a>.
Any bugs determined to be a RedHat bug will be forwarded
on.
</li>
</ul>

<p>
<ul>
<li>
Making a boot
floppy may not work due to the size of the kernel and necessary
modules.  Instead of a boot floppy, the install CD can be used for
rescue by typing "linux rescue" at the boot prompt.
</li>
<p>
<li>
If you get an "invalid video mode" at boot time,
simply press &lt;RETURN&gt; and choose a video mode from the list ("0" should
work fine).
</li>
</ul>
