Overview of MFS

MooseFS is a network distributed file system with fault tolerance. It distributes the data on multiple physical servers and presents a unified resource to the user.

Advantages 1, high reliability (multiple copies of data are stored on different computers) 2, dynamic expansion of capacity can be achieved by attaching new computers or hard drives 3, deleted files can be retained according to a configurable time period (a file system level recycle bin) 4, Master server cannot solve single point of failure component metadata server (Master) of MFS: responsible for managing the file system throughout the system Maintain metadata, high availability is not currently supported. Metadata log server (MetaLogger): back up the change log files of the Master server. When the master server is damaged, you can recover the files from the log server. Data storage server (Chunk Server): the more servers that actually store data, the larger the capacity, the higher the reliability, and the better the performance. Client (Client): the experimental topology diagram of the MFS file system can be mounted like NFS.
