Embodiment Construction

[0016] The present invention will be further explained in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] A distributed file system includes multiple modules: data server (DS), metadata storage server (MOS), metadata operation server (MPS) and client (Client). The architecture implemented by the present invention is as figure 1 As shown, the client reads metadata from MPS, updates metadata to MOS, and interacts with DS to complete data read and write operations. Since the I / O operation of data is not involved in the present invention, the role of DS does not need to be considered.

[0018] The following protocols are mainly designed in the present invention:

[0019] The metadata reading access protocol between the client and the MPS: all clients access the same metadata on a fixed MPS through hash; if a certain MPS is overloaded and causes a timeout, the client automatically selects the next adjacent MPS to access the metadata....

Abstract

The invention provides a distributed file system metadata management method. By separating the read-only operation and the modification operation of a metadata server, disc access frequency caused by read-only operation I / O of metadata at an MOS (management operating system) end is reduced, and the performance of data modification operation at the MOS end is improved; by mapping the metadata hash on different MPSs (microprocessor system), the cache hit ratio of the MPSs is improved, and the performances of the metadata server is further improved. Moreover, access of a client and the MPSs to the metadata is shielded when the metadata are modified by theMOSs, and the isolation of the modification operation on the metadata is guaranteed.

Description

technical field [0001] The invention relates to the technical field of computer storage, in particular to a metadata management method of a distributed file system. Background technique [0002] With the rapid development of network technology and the increasing amount of information, computer storage technology has gradually become the focus of people's attention. With its unique high fault tolerance, high cost performance and high scalability, the distributed parallel file system conforms to the trend of explosive growth of information, and has attracted the attention of researchers and storage manufacturers. [0003] In a distributed parallel file system, the performance of metadata processing has a great impact on the performance of the file system. In the case of intensive metadata operations, the metadata processing capability even becomes the bottleneck restricting the file system, so how to improve the metadata processing capability is a research focus of the curren...
