Distributed Replicated Storage Across Four Storage Nodes With GlusterFS On Fedora 12
This tutorial shows how to combine four single storage servers (running Fedora 12) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network. If you lose one server from replication1 and one from replication2,the distributed volume continues to work. The client system (Fedora 12as well) will be able to access the storage as if it was a localfilesystem. GlusterFS is a clustered file-system capable of scaling toseveral peta-bytes. It aggregates various storage bricks overInfiniband RDMA or TCP/IP interconnect into one large parallel networkfile system. Storage bricks can be made of any commodity hardware suchas x86_64 servers with SATA-II RAID and Infiniband HBA.
