Distributed file system, and data storage processing method and data storage processing device thereof

Abstract

The embodiment of the invention provides a distributed file system, and a data storage processing method and a data storage processing device thereof. The method comprises the following steps of: receiving an access request sent by a client of the distributed file system; determining a storage unit to be accessed by the client of the distributed file system and the status of a virtual resource pool corresponding to the storage unit according to the access request, wherein same data is stored in the storage unit and the virtual resource pool corresponding to the storage unit and the virtual resource pool is generated by clustering according to the client of the distributed file system having a same activity cycle; and returning an access response message including a client identifier to the client of the distributed file system initiating the access request, when determining that the virtual resource pool corresponding to the storage unit is in an on-line status, wherein the client of the distributed file system identified by the client identifier is one of the virtual resource pools. The invention further provides the corresponding device and the distributed file system. By the technical scheme, the system stability of the distributed file system can be improved.

Description

technical field [0001] The data storage technology of the present invention particularly relates to a distributed file system and its data storage and processing method and device. Background technique [0002] A Distributed File System (Distributed File System, hereinafter referred to as DFS) is a file system based on a client / server model. The DFS in the prior art includes a name space server, a content storage server and a client, specifically as figure 1 As shown, the name server stores the specific storage unit of the data blocks of each file in the content storage service. The specific storage unit can be in various forms such as ordinary disks, disk arrays, etc., which can be represented by storage unit identifiers, When the client wants to read the stored data, it first requests the stored storage location from the name space server, and the name server provides the above storage location information, and then the client accesses the content storage server according...

AI Technical Summary

Problems solved by technology

[0003] The distributed file system and the corresponding storage data acquisition method provided in the above-mentioned prior art need to maintain the working status of the content storage server in the DFS system at all times to provide services for the client, which has the disadvantage of high energy consumption. If some or all of the storage units are powered off, the files stored in the corresponding storage units cannot be provided to the client, and the stability of the distributed file system is poor.
