Comments on Distributed Storage Across Four Storage Nodes With GlusterFS On CentOS 5.4
This tutorial shows how to combine four single storage servers (running CentOS 5.4) to one large storage server (distributed storage) with GlusterFS. The client system (CentOS 5.4 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

This article is VERY outdated. As of November 2010, with version 3.1 of glusterfs, these instructions are incorrect.
For the latest Glusterfs documentation see: http://gluster.org/community/documentation/index.php/Main_Page
CAUTION: Gluster configuration has changed since this article was written. The Refer to the Gluster Information Wiki for the current steps+commands to configure Gluster.
