MooseFS Alternatives

MooseFS

MooseFS is a fault-tolerant distributed file system. It spreads data over several physical locations
(servers), which are visible to user as one resource. For standard file operations MooseFS
acts as any other Unix-alike filesystem:
• Hierarchical structure (directory tree)
• Stores POSIX file attributes (permissions, last access and modification times)
• Supports special files (block and character devices, pipes and sockets)
• Symbolic links (file names pointing to target files, not necessarily on MooseFS) and hard
links (different names of files that refer to the same data on MooseFS)
• Access to the file system can be limited based on IP address and/or password
Distinctive features of MooseFS are:
• High reliability (several copies of the data can be stored on separate physical machines)
• Capacity is dynamically expandable by adding new computers/disks
• Deleted files are retained for a configurable period of time (a file system level ”trash bin”)
• Coherent snapshots of files, even while the file is being written/accessed
