LinuxProgramming.com: Highlight Project: GFS (Global File System)

(Other stories by Lou Grinzo)

"The Global File System (GFS) is a 64-bit shared disk cluster file system for Linux. GFS cluster nodes physically share the same storage by means of Fibre Channel or shared SCSI devices, and makes the entire file system appear to be local on each node. GFS is also fully symmetric, meaning that all nodes are equal and there is no server which may be a bottleneck or single point of failure. GFS uses read and write caching while maintaining full UNIX file system semantics and supporting journaling, recovery from client failures, and many other features."

..."Why Highlighted: GFS is easily one of the more interesting "stealth projects" running on Linux today (but hopefully this Highlight Project article will help de-cloak it somewhat). It's also an excellent example of the kind of heavy-duty, enterprise class development and deployment that Linux supports. Perhaps most important of all, GFS can serve as a test bed for further work in clustering and file sharing. Plus, true geeks can never have too many cool file systems to experiment with."
