MooseFS is an open source distributed file system actively developed and maintained by Gemius SA (http://www.gemius.com), a Poland-based online research agency.
Apart from the common features of distributed file systems, the usage of MooseFS with OpenNebula is encouraged due to some particular features, which are as follows:
Snapshots: It is possible to make real-time snapshots of directories and files.
Expandability: Redundancy is not defined by volume layout during creation like that of GlusterFS, but on a directory or file level. Every storage server that gets added to the cluster is automatically introduced and its space is immediately made available.
Automatic re-balancing: As soon as something bad happens to a storage server, missing copies are immediately replaced by new copies on remaining storage servers. If a storage server comes back online, it will get resynchronized automatically and the file copies that are in excess will be discarded.
