Embodiment Construction

[0032] The main idea of ​​the present invention is that the client creates a file description structure locally, the file description structure includes a data stream information for storing metadata data streams, and directly Update the file description structure.

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] According to an embodiment of the present invention, a collaborative storage method of a distributed file system is provided.

[0035] First, extend a data stream attribute to the metadata of the file to make full use of the storage capacity of the metadata server, refer to Figure 5 , Figure 5 is a schematic diagram of a metadata extension data stream field according to an embodiment of the present invention. like Figure 5 As shown, the metadata field attributes...

Abstract

The invention discloses a distributed file system and an associated storage method thereof, wherein the method comprises the following steps of: establishing a file description architecture by a client end, wherein the file description architecture comprises data stream information and is used for storing data stream fields of metadata expanded in advance; and when the client end carries out a writing operation, writing the data stream information of the file description architecture. Through the invention, the writing speed and the integral concurrent processing capacity of the system can be improved.

Description

technical field [0001] The invention relates to the field of communication, in particular to a distributed file system and a co-storage method thereof. Background technique [0002] A distributed file system generally includes a metadata server (Metadata Server) and multiple data servers (Data Server), accessed by multiple clients (Client), such as figure 1 Shown: [0003] Files are divided into blocks of fixed size (CHUNK) and stored on the Data Server. To ensure reliability, each CHUNK can be stored on multiple Data Servers. [0004] Metadata Server manages all metadata of files, including file namespace, access control information, mapping information from files to CHUNKs, and the current location of CHUNKs. It also manages system-wide activities such as chunk lease management, garbage collection of orphaned chunks, and movement of chunks between Data Servers. Metadata Server periodically communicates with each Data Server with heartbeat information, giving them instru...
