Our research project is currently using GlusterFS for our distributed NFS storage system. We're leveraging the distributed-replica configuration in which every two pairs of servers is a replica pair, and all pairs form a distributed cluster. We do not do data stripping since to achieve up-time reliability with stripping would require too many servers.
Furthermore, another nice feature of GlusterFS, is that you can just install it into a VM, clone it a few times, and distribute them across VMMs. However, we utilize physical servers using RAID-1. One issue with MooseFS is that it relies upon a single Metadata server. Therefore, if that Metadata server fails, the cluster fails. GlusterFS does not have a Metadata server. -- Sincerely, Hutson Betts (Computer Science and Engineering - Texas A&M University) Key ID: F98BFC1E <http://pgp.mit.edu/> On Wed, 2012-02-08 at 11:15 -0500, Maxim Mikheev wrote: > Hi Joao. > I made a similar search recently.
