Tutorial: Create an NFS-like Storage Server with GlusterFS on Ubuntu 12.10

Up
vote
Down

This tutorial shows how to set up a standalone storage server on Ubuntu 12.10. Instead of NFS, I will use GlusterFS here. The client system 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. read more...

But even though being simpler in features and output it is still an essential process management/monitoring tool that every linux newbie should know about and learn well. read more...
