MooseFS is a Petabyte Open Source Network Distributed File System.
MooseFS is easy to deploy and maintain, highly reliable, fault tolerant, highly performing, easily scalable and POSIX compliant.
MooseFS spreads data over a number of commodity servers, which are visible to the user as one resource. For standard file operations MooseFS acts like ordinary Unix-like file system.
- High reliability – files are stored in several copies on separate servers. The number of copies is a configurable parameter, even per each file.
- No Single Point of Failure – all hardware and software components may be redundant.
- Parallel data operations – many clients can access many files concurrently.
- Capacity can be dynamically expanded by simply adding new servers/disks on the fly.
- Retired hardware may be removed on the fly.
- Deleted files are retained for a configurable period of time (a file system level “trash bin”).
- Coherent, “atomic” snapshots of files, even while the files are being written/accessed.
- Access to the file system can be limited based on IP address and/or password (similarly as in NFS).
- Data tiering – supports different storage policies for different files/directories in Storage Classes mechanism.
- Per-directory, “project” quotas – configurable per RAW space, usable space, number of inodes with hard and soft quotas support.
- Apart from file system storage, MooseFS also provides block storage (mfsbdev).
- Efficient, pure C implementation.
- Ethernet support.
