MooseFS Master-Chunk
Port 9420 is primarily used by MooseFS, an open-source distributed file system, facilitating communication between the Master Server and Chunk Servers to coordinate file storage and management efficiently across distributed infrastructure..
MooseFS Overview: MooseFS is a fault-tolerant, open-source distributed file system designed to span multiple servers, providing a single namespace accessible by clients. It offers high availability and scalability for storing large amounts of data, typically used in cloud environments, high-performance computing, and data centers.
Master and Chunk Server Interaction: Within the MooseFS architecture, the Master Server manages metadata—the directory structure, file system namespace, file locations, access permissions, and system status. Chunk Servers, on the other hand, store the file data as chunks. Communication over port 9420 enables the Master Server to orchestrate where chunks are stored, synchronize status information, and dispatch maintenance instructions, ensuring data integrity and redundancy.
Port-Specific Functionality: Port 9420, by default, facilitates TCP-based internal communication pathways necessary for system operation, encompassing chunk registration, heartbeat signaling, replication coordination, and failure detection. This internal management is critical for maintaining a consistent and reliable distributed storage architecture.
