Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0052] In a distributed file system, for the sake of data security, a stripe usually has at least two data blocks. In at least two data blocks of a stripe, regardless of the encoded storage method or the backup storage method, when a data block is invalid and data cannot be read from this data block, other valid data can be used Data in the block for data recovery to read the data. Wherein, the valid data block means that data can be read from the data block....

Abstract

The invention provides a data storage mode conversion method. The data storage mode conversion method is applied to a data storage mode conversion system. The system comprises a data processing server, an encoding processing server and information management equipment. The method comprises the steps of a data processing server being used for storing original data into a backup type storage strip;when the backup type storage strip successfully stores the data, setting the state of the backup type storage strip to be a first preset state by utilizing the information management equipment; when the encoding processing server meets a preset encoding condition, acquiring target data stored in the target backup type storage strip by utilizing the encoding processing server, and generating encoded data corresponding to the target data; and storing the target data and the coded data to a coded storage strip by using a coding processing server. According to the method, the data processing server is separated from the coding processing server, and the backup storage process is separated from the data storage mode conversion process, so the load pressure of each server in the system is reduced on the whole.

Description

technical field [0001] The present invention relates to the technical field of data storage, and more specifically, to a method and system for converting data storage modes. Background technique [0002] In a distributed file system, after the data is stored in backup form, it is usually required to be stored in encoded form. In backup storage, the storage space ratio of original data and mirrored data is at least 1:1; while in encoded storage, the storage space ratio of original data and encoded data is usually 2:1, or even greater. It can be seen that the coded storage method can save data storage space more than the backup storage method. [0003] At present, in the process of converting data from backup storage to encoded storage, it is usually a data processing server that reads the data in the data processing server immediately after a backup storage stripe is full. The data is encoded, and then the encoded data is stored in the encoded storage stripe. However, in t...
