An open-source, petabyte-scale, fault-tolerant distributed file system with POSIX compliance and easy scalability.
MooseFS is an open-source distributed file system that aggregates storage from multiple commodity servers into a single, petabyte-scale namespace. It solves the problem of scalable, fault-tolerant storage by replicating data across servers and providing POSIX-compliant file operations. The system is designed for environments that require high performance, reliability, and easy expansion without proprietary hardware.
System administrators, DevOps engineers, and organizations needing scalable, fault-tolerant storage solutions for data-intensive applications, backups, or media storage.
Developers choose MooseFS for its combination of POSIX compliance, ease of deployment, and robust feature set including dynamic scalability, no single point of failure, and built-in data protection mechanisms like snapshots and a trash bin.
MooseFS Distributed Storage – Open Source, Petabyte, Fault-Tolerant, Highly Performing, Scalable Network Distributed File System / Software-Defined Storage
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Files are stored in multiple configurable copies across separate servers, ensuring no single point of failure and robust data protection against hardware failures.
Capacity can be expanded or reduced on the fly by adding or removing servers and disks, as highlighted in the README under distinctive features, allowing seamless growth.
Supports hierarchical directory trees, file attributes, ACLs, distributed file locks, and special files, making it behave exactly like a traditional Unix file system for compatibility.
Includes a file system-level trash bin for deleted files and atomic snapshots, providing recovery options and coherent backups without interrupting access.
Allows limiting access based on IP address and password, and offers per-directory project quotas for space and inodes, aiding in resource management and security.
Requires installing and configuring multiple components (master server, chunkservers, client) with manual steps like copying config files and setting permissions, which can be error-prone and time-consuming.
Access control is basic (IP/password-based), and the README does not mention encryption for data at rest or in transit, which may be insufficient for regulated or sensitive environments.
Clients rely on FUSE libraries, which might not be stable on all systems, and the Windows client requires third-party Dokany, adding compatibility and maintenance hurdles.
As a distributed system, MooseFS can introduce latency for metadata operations, especially with small files, due to network overhead and replication, though not explicitly stated, it's a common drawback.
