RozoFS

RozoFS is a free software distributed file system. It comes as a free software, licensed under the GNU GPL v2. RozoFS uses erasure coding for redundancy.
Design.
Rozo provides an open source POSIX filesystem, built on top of distributed file system architecture similar to Google File System, Lustre or Ceph. The Rozo specificity lies in the way data is stored. The data to be stored is translated into several chunks using Mojette Transform and distributed across storage devices in such a way that it can be retrieved even if several pieces are unavailable. On the other hand, chunks are meaningless alone. Redundancy schemes based on coding techniques like the one used by RozoFS allow to achieve significant storage savings as compared to simple replication.
The file system comprises three components:
