Problems solved by technology

[0004] The main purpose of the present invention is to provide a data reconstruction method, equipment, storage medium and device, aiming at solving the problem of not considering the reconstruction load of each storage node when reconstructing abnormal data fragments in the prior art. As a result, individual storage nodes have a large load, which in turn leads to technical problems such as slow reconstruction of data shards and poor stability

Abstract

The invention discloses a data reconstruction method, equipment, a storage medium and a device, and the method comprises the steps: obtaining the reconstruction load capacity of each storage node when a data fragment reconstruction request is received, selecting a target storage node from the storage nodes according to the reconstruction load capacity, reading a target data fragment in the target storage node, determining an abnormal data fragment according to the target data fragment, and performing data reconstruction on the abnormal data fragment. The target storage node is selected according to the reconstruction load capacity of each storage node, and data reconstruction is performed based on the target data fragment of the target storage node, so that the load capacity of individual storage nodes is prevented from being too large, the data fragment reconstruction speed is shortened, and the data fragment reconstruction stability is improved.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a data reconstruction method, equipment, storage medium and device. Background technique [0002] At present, when a distributed storage system reconstructs data shards, it often selects storage nodes with smaller shard serial numbers to reconstruct abnormal data shards. However, the above reconstruction method does not consider the reconstruction load of each storage node, resulting in a large load of individual storage nodes, which in turn leads to slow reconstruction of data fragments and poor stability. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the present invention is to provide a data reconstruction method, equipment, storage medium and device, aiming at solving the...
