Tuesday May 1 2001: SGI is pleased to announce the 1.0 release of XFS^tm, a high-performance journaled filesystem for Linux.

Update: Release 1.0.1 of SGI XFS is now available. For information on the 1.0.1 release, please see the XFS for Linux Release 1.0.1 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 late 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:

• Advanced features:
  • Fast recovery 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
  • XFS 1.0 is distribution-independent and is certified with the Linux Kernel (2.4.x) For those using Red Hat Linux, an installer is available. Other installers are under development in the community.
  • 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.
