Distributed file system what is a distributed file system? (1) distributed file system means that the physical storage resources managed by the file system are not necessarily directly connected to the local node, but are connected to the node through the computer network (2) the design of the distributed file system is based on the characteristics of the distributed file system in the client / server model. (1) A file system that is fixed in a location. Extend to any number of locations / multiple file systems (2) each node can be distributed in different locations Communication and data transmission between nodes through the network infrastructure client-master server | data server 1 data server 2 data server 3. Data server n (the data is stored on a server cluster, and the entire file system service is provided by the servers in the cluster) the master server-- master manages each data server, assigns tasks-- all the file directory information is placed on the master server, looking for files. Must access it data server-store data-redundancy mode FastDFS FastDFS server has two roles: tracker (tracker) and storage node (storage)-tracker: mainly does scheduling work, plays a load balancing role in access-storage node: performs all the functions of file management, that is, storage, synchronization and provides access interface At the same time, the metadata of files is managed. FastDFS adopts grouping storage mode-the cluster is made up of one or more groups. The total storage capacity of the cluster is the sum of the storage capacity of all groups in the cluster.
