A set of commands to work with XFS filesystems, including mkfs.xfs(8). XFS is a high performance journaling filesystem which originated on the SGI IRIX platform. It is completely multi-threaded, can support large files and large filesystems, extended attributes, variable block sizes, is extent based, and makes extensive use of B-trees (for directories, extents, free space) to aid both performance and scalability.
