RedHat's enterprise operating system doesn't provide support for XFS out of the box, due to support limitations. XFS is a mature and stable file system however, and has benefits in a number of areas, including file streaming, snapshotting, growing, and online defragmentation. In this brief article, I'll walk you through the process of adding XFS support to your RHEL5 (or CentOS) boxes.
XFS comes in two parts: userland tools (xfsprogs) for creating/checking/etc XFS partitions and xfs-kmod, the kernel module required to support XFS.
RedHat is one of the most widely used Linux distribution, at least in the corporate and academic sectors. It's been around for years and after all the shit they've gotten from users trapped in RPM "dependency hell," you'd think they'd have learned SOMETHING by now, right?...Right?
