MooseFS – POSIX-compliant distributed file system

Last Updated on October 7, 2023

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.

Key Features

• 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.
