High-Availability Storage With GlusterFS On Fedora 12 – Automatic File Replication (Mirror) Across Two Storage Servers

This tutorial shows how to set up a high-availability storage with two storage servers (Fedora 12) that use GlusterFS.
Each storage server will be a mirror of the other storage server, and
files will be replicated automatically across both storage servers. The
client system (Fedora 12 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.
