XFS(5)

NAME
xfs - XFS file system

SYNOPSIS
To link into the kernel:

options XFS

To load as a kernel loadable module:

    kldload xfs

DESCRIPTION
The xfs driver will permit the FreeBSD kernel to access XFS file systems.

EXAMPLES
To mount a xfs volume located on /dev/ad1s1:

    mount -t xfs -o ro /dev/ad1s1 /mnt

SEE ALSO
nmount(2), unmount(2), fstab(5), mount(8)

NOTES
The sysutils/xfsprogs port contains the mkfs.xfs utility for creating XFS file systems, and also other utilities for analyzing, and repairing XFS file systems.

HISTORY
XFS was originally written by SGI for the IRIX operating system. SGI ported XFS to Linux, and released the source code under the GNU Public License. For more details, see: http://oss.sgi.com/projects/xfs

The port to FreeBSD was based on the Linux port, and started by -nosplit Russell Cattelan <cattelan@xfs.org>, Alexander Kabaev <kan@FreeBSD.org>, and Craig Rodrigues <rodrigc@FreeBSD.org>.

The xfs file system support first appeared in FreeBSD 7.0.

CAVEATS
The port of XFS to FreeBSD is currently incomplete. Only read-only access is supported for XFS volumes. Writing to a volume is not supported.

The -p flag to mkfs.xfs can be used to create an XFS file system which is populated with files and other metadata. This can be used to quickly create a read-only file system which can be tested on FreeBSD.
