SGI XFS Linux Release 1.0

On May 1 2001, SGI made available Release 1.0 of its high-end XFS file system for Linux. XFS for Linux version 1.0 works with a Linux 2.4.x-based kernel.

Release 1.0.1 of SGI XFS is now available. For information on the 1.0.1 release see the XFS for Linux Release 1.0.1 New Features page.

For links to articles on XFS and journaled filesystems, see XFS in the News.

XFS Availability and Release Caveats

SGI XFS Linux Release 1.0 is available as a patch against linux-2.4. XFS 1.0 is distribution-independent. An installer for Red Hat Linux v7.1 is available today. Other installers are under development in the community. The Red Hat Linux installation media installs a Red Hat Linux v7.1 system with XFS on root, or any other partition, right out of the box.

Before installing the XFS filesystem for Linux, you should look over the XFS for Linux Release 1.0 Caveats for a list of limitations, requirements, and special instructions for this release.

Because this release requires a 2.4 kernel, it may require some updates to your system if you are currently running the 2.2.x series kernels. Please see the latest Linux 2.4 Changes document for details on the minimum levels of software necessary to install and run a Linux 2.4 kernel.

Step by step instructions are provided for the following installations:
