LXer: High-Availability Storage Cluster With GlusterFS On Ubuntu
Published at LXer:
In this tutorial I will show you how to install GlusterFS in a scalable way to create a storage cluster, starting with 2 servers on Ubuntu 8.04 LTS server. Files will be replicated and splitted accross all servers which is some sort of RAID 10 (raid 1 with < 4 servers). With 4 servers that have each 100GB hard drive, total storage will be 200GB and if one server fails, the data will still be intact and files on the failed server will be replicated on another working server. 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 server with SATA-II RAID and Infiniband HBA.
