Abstract

The invention provides a method and a device for processing files in a distributed file system. The method includes: receiving a user's file operation request which at least includes file description information and an operation type; determining a meta main node used for storing metadata of the file from all nodes of a metadata server according to the file description information, and forming a distributed hash table network by all nodes of the metadata server; determining a block main node used for storing data block of the file from all nodes of a data block server according to the file description information, and forming a distributed hash table network by all nodes of the data block server; and finishing an operation between the meta main node and the block main node according to the operation type. The device comprises a receiving module, a routing determination module and a processing module. By the method and the device, expansion of the distributed file system and mass file content storage can be effectively achieved.

Description

technical field

[0001] The present invention relates to data processing technology, in particular to a file processing method and device in a distributed file system (Distributed File System, DFS for short). Background technique

[0002] The storage system of the distributed file system can effectively meet the storage of massive data content of Internet business. Taking Google's distributed file system (Google File System, referred to as: GFS) as an example, the GFS cluster consists of a metadata server (master node) and multiple block servers (chunk servers). There are periodic heartbeats between chunkservers to communicate with each other, and the heartbeat communicates information and status of the chunkservers. The metadata server is responsible for managing the metadata of the file system of all files. The metadata may include information such as namespace, access control information, mapping relationship between files and blocks, and the location of the current block...
