Abstract

The invention discloses a method and device for checking data consistency of a distributed storage system, equipment and a computer readable storage medium, and the method comprises the steps: receiving a check request sent by a client, and judging whether the state information of a target object under different nodes of a distributed storage system is the same or not in a data reading and writingprocess; if the inconsistent state information exists in the plurality of redundant objects, judging whether the number of objects with consistent state information in the plurality of redundant objects is greater than or equal to a preset number threshold value or not; and if the number of the redundant objects is greater than or equal to the preset number threshold, judging that the data of theredundant objects is consistent, and processing inconsistent data in the redundant objects by utilizing a pre-established negotiation mechanism, so that the data of the redundant objects is completely consistent. According to the method, the device, the equipment and the computer readable storage medium provided by the invention, the data consistency checking efficiency is improved, and the influence on the cluster performance is reduced.

Description

technical field [0001] The present invention relates to the technical field of distributed storage, in particular to a method, device, device and computer-readable storage medium for checking data consistency of a distributed storage system. Background technique [0002] Today, with the rapid development of computer technology, data is growing explosively; not only are the IO performance requirements of distributed storage systems getting higher and higher, but at the same time, the security and correctness of data storage are getting more and more attention. Data security can be guaranteed by data redundancy rules. However, considering the correctness of the data, the distributed storage system is composed of multiple nodes, and the hardware of each node, such as: memory, CPU, network card, disk, etc., may be damaged; it may lead to inconsistency of multiple redundant data, which will eventually affect correctness of the data. [0003] In the prior art, there are two meth...
