Embodiment Construction

[0051] The embodiment of the present invention provides a method, device and data node server for information reporting, which are used to solve the short-term overtime offline, the data node server reports the full amount of metadata information to the metadata server. The problem caused by the inconsistency of the metadata information of the data server to report in full.

[0052] In the technical solution provided by the embodiment of the present invention, when the data node server registers with the metadata server for the first time, it reports the metadata information of all data blocks on the data node server to the metadata server, and records the metadata information reported to the metadata server. The index startIndex of the last data block sorted according to the index in the data information.

[0053] When the data node server is not registering with the metadata server for the first time, the data node server will report to the metadata server the index of some ...

Abstract

The invention provides an information reporting method, an information reporting apparatus and a data node server, and is used for reducing the time-delay for meta-data information synchronization between a data node server and a meta-data server, and reducing the burden which is brought by reporting of large amount of meta-data information to the meta-data server. The method comprises determining the meta-data information, of a data block, to be reported to the meta-data server when there is requirement for reporting the meta-data information of the data block to the meta-data server, wherein if it is the first time for a data node server to report the meta-data information of the data block, the reported meta-data information of the data block includes the meta-data information of all the data blocks in the data node server, and if it is not the first time for the data node server to report the meta-data information of the data block, the reported meta-data information of the data block is the meta-data information of part of the data blocks in the data node server; and reporting the reported meta-data information of the data blocks to the meta-data server by the data node server.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an information reporting method, device and data node server. Background technique [0002] The distributed object file system is used to manage massive storage resources and provide high-speed, stable, and linearly scalable services. In the distributed object file system, each file is divided into multiple objects (Object), and each object is further divided into N data blocks (Block), and the N data blocks are stored in N different data blocks. on the node server. [0003] The structure of the distributed file system is as follows figure 1 shown. Wherein, a data node server (referred to as Data Node) is used to store data blocks and metadata information of these data blocks. The metadata server (Metadata Server, MDS for short) is used to store the metadata information of the database, and the metadata information is the information used to describe the data block, sp...
