XFS: A high-performance journaling file system

On May 1 2001, SGI announced the 1.0 release of its high-end XFS^tm journaled filesystem for Linux®. As a leading supporter of Linux and the open source movement, SGI is providing a reliable, resilient, scalable, high-performance filesystem for business-critical Linux infrastructure.

More information is available on the SGI XFS Linux Release 1.0 page. For information on the software changes that have been made since Pre-Release 0.10, see the XFS for Linux Release 1.0 New Features page.

XFS, widely recognized as the industry-leading high-performance filesystem, provides rapid recovery from system crashes and the ability to support extremely large disk farms. XFS is the first journaled filesystem for Linux available today that has a proven track record in production environments since December, 1994. It is a mature technology that has been proven on thousands of IRIX systems as the default filesystem for all SGI customers.

XFS Linux 1.0 is released for the Linux 2.4 kernel and offers the following unique advantages:

• Extensive features not generally available in other Linux filesystems:
  • Fast recovery time after a system crash or power failure (fsck not needed)
  • Journalling for guaranteed filesystem integrity
  • Direct I/O
  • Space preallocation
  • Transactionally recorded quotas
  • Access control lists and Extended attributes
  • Infrastructure for XDSM support
  • Excellent overall performance
  • Excellent scalability (64 bit filesystem)
• A complete toolset including:
  • dump/restore support including all XFS filesystem features such as ACLs and quotas
  • Repair utility, filesystem editor, and growing the filesystem
  • Modified Red Hat installer to allow system installation on XFS
  • ACL editing utility

• Excellent integration with other Linux subsystems:
  • NFS server support
  • Root filesystem and lilo support
  • Software raid integration with md and lvm packages
  • Mount by label and mount by uuid
• Maintains on-disk compatibility with XFS filesystems created under IRIX

XFS is licensed under GPL.
