SGI XFS 1.0.1 for Linux
This directory contains the 1.0.1 XFS release for Linux.
For more information, see http://oss.sgi.com/projects/xfs
The 2.4.5 kernel RPMS are vanilla 2.4.5 kernels (Linus' tree) with the
same XFS bits as above.
The 2.4.3 kernel RPMS are based on Red Hat's 7.1 2.4.3 kernel version -
only the XFS bits have been changed. These RPMS are intended
for anyone using XFS on RH 7.1 in an environment where they
need Red Hat's kernel improvements, and they do not wish
to jump kernel versions to get XFS improvements.
The patches provided are for linux-2.4.5. They are now
broken into 2 patches, one for files unique to XFS,
and one that modifies existing core Linux files.
kdb patches are also provided for debugging.
See the README file in the patches/ directory for patching
Userspace commands are provided both as tarballs and
The installer/ directory contains a modified Red Hat 7.1
installer that will allow you to install a Red Hat 7.1 system
on XFS. If you already used the XFS 1.0 system installer,
there is no need to re-install, simply upgrade your RPMs.
A new system installer was provided for a few people who,
due to bugs in the 1.0 release, were unable to use the
