Abbreviated as GFS, a
Global File System is a cluster
file system that enables a
cluster of computers to simultaneously use a
block device that is shared between them. GFS reads and
writes to the block device like a local file system, but also allows the
computers to coordinate their
I/O to maintain file system
consistency. With GFS any changes that are made to the file system on one
computer will immediately be seen on all other computers in that cluster.
