Bill von Hagen provides a detailed technical overview of the Coda distributed filesystem for Linux in this article at LinuxPlanet . . .

“The initial article in this series at LinuxPlanet provided an overview of the basic principles of distributed filesystems, and highlighted several of the most popular and up-and-coming distributed filesystems that are available for Linux today. The previous articles explored the InterMezzo distributed filesystem and explained how to install and configure a simple InterMezzo client and server. This article explores the Coda distributed filesystem that provided much of the inspiration for InterMezzo and which is also readily available for Linux.”

“Coda is a well-established distributed filesystem that was developed at Carnegie-Mellon University, is actively in use there, and is also still actively under development. Coda began life as a variant of the AFS distributed filesystem (version 2) from Carnegie-Mellon University, but has since taken on a complete life of its own. Led by M. Satyanarayanan, the Coda filesystem project is focused on specific distributed filesystem functionality required for mobile computing, such as support for disconnected operation. As explained in the article on InterMezzo, 'disconnected operation' is the term used to describe the situation where a system that is ordinarily a part of a networked, distributed filesystem, is used without being connected to a network . . .”
