Abstract

The invention discloses a data updating method, and the method comprises the steps: receiving an updating writing instruction of target data, and determining a target hard disk, corresponding to the target data, in a distributed storage system; marking a hard disk with abnormal working state in the target hard disk as an abnormal hard disk; selecting an alternative hard disk with a normal workingstate from the distributed storage system; and setting an alternative hard disk and the target hard disk with a normal working state as a redundant hard disk group of the target data, and executing anupdate write operation corresponding to the update write instruction on the redundant hard disk group. The influence of abnormity of the distributed storage system on the data redundancy can be avoided, and the data reliability is improved. The invention further discloses a data updating device, a storage medium and electronic equipment, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of storage technologies, and in particular to a data updating method and device, an electronic device and a storage medium. Background technique [0002] With the rise of hyper-converged architecture, distributed storage technology has become a common data storage technology. Storing data based on distributed storage technology can improve data security and reliability, and meet the data storage requirements of big data. [0003] The nodes in the distributed storage system are connected through the network. Each node includes a certain number of hard disks. The data to be stored can be transmitted to different nodes in the redundancy group through the network, and then written to the hard disks of different nodes. . When the network or nodes are abnormal, the data to be stored cannot be written to the corresponding hard disk, resulting in a reduction in the amount of redundant data and a decrease in the dat...
