Global File System

Jump to: navigation, search

A Global File System (Abbreviated as GFS) can be referred to as a cluster file system that permits a network of computers to concurrently use a block device that is pooled between them.

It reads and writes to the block device like any local file system, but also enables the computers to synchronize their I/O to uphold file system uniformity. With GFS any modifications that are carried out on to any file system on single system can be instantaneously seen on all other computers in that network.
