Translation of the article

Global Spins System (GFS) is a filesystem conceived to share data via a cluster of computer Linux or Irix. GFS is different from the filesystems distributed like AFS, Coda, or InterMezzo because it requires that all the nodes have a competitor access to the same peripheral of storage ( shared block device ).

GFS does not function in disconnected mode, it does not have there either of customer or of waiter, all the nodes of a cluster GFS are equal. GFS is a free software, distributed under license LPG.

The fiber Chanel, the iSCSI, or the systems AoE (ATA over Ethernet) are often used for the shared data of GFS. GFS depends on a manager of lock distributed like GULM or GDLM.

History

GFS was developed at the origin by a doctorand with the university of Minnesota. Later it was taken again by the company Sistina Software in the form of a project open source. In 2001 Sistina decided to market GFS, giving up occasion consequently management in open source. OpenGFS was then created starting from the free last version of GFS.

In December 2003 Red Hat bought Sistina. In June 2004, Red Hat delivered GFS and many cluster infrastructure parts in the form of license LPG. Red Hat apart from the corrections of bug and stabilization) succeeded in making include GFS and its distributed lock to manage (DLM) dedicated in the core Linux version 2.6.19.

Here some versions with the major changes which they introduce:

v1.0 (1996) compatible version SGI IRIX only
v3.0 bearing under administrative Linux
v4 journalizing
v5 of redundant lock
v6.1 (2005) administrative of lock distributed (DLM)
