MooseFS is an open-source, POSIX-compliant, petabyte-scale network distributed file system written in C. It spreads data across commodity servers with configurable replication, snapshots, trash bin, quotas, and block storage, presenting itself to clients as a single mounted resource via FUSE.

Use cases

• build a petabyte-scale storage cluster from commodity hardware
• mount a fault-tolerant POSIX file system shared across many servers
• store backups with configurable replication and a trash bin for deleted files
• provide block storage for VMs and databases
• run high-performance computing cluster storage
• scale storage capacity by adding servers without downtime
• take atomic snapshots of files while they are being written
• apply per-directory quotas and storage tiering policies

When to choose

• you need a POSIX-compliant distributed file system that mounts like a local disk
• you want fault tolerance with no single point of failure on commodity hardware
• you need dynamically expandable capacity and on-the-fly hardware removal
• you run HPC or large data workloads requiring parallel access to many files
• you want snapshots, quotas, and data tiering built into the file system

When to avoid

• you only need object storage for cloud-native apps (use S3-compatible systems instead)
• you need a single-node file system with no cluster overhead
• you require native Windows client support in the free edition (Windows client is PRO-only)
• you need geo-replication across datacenters without the PRO edition
• your workload is small enough that NFS or a local disk would suffice
