"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." Read all about it at LinuxProgramming.com.
