Abstract

The invention provides a data recovery control method and device based on erasure codes, equipment and a medium, and the method comprises the steps: storing data according to a preset erasure ratio, the data comprising source data and verification data; when the disk is online, loading source data index information, and after loading is completed, representing a source data index loading state through a source data loading identifier; then, loading index information of the verification data, and after loading is completed, representing a verification data index loading state through a verification data loading identifier; and according to all the source data loading identifiers and the verification data loading identifiers, controlling data reporting, preferentially acquiring the source data, and after the source data is processed, processing the verification data to complete data recovery. According to the method, the source data and the verification data are distinguished through the identifier, and the mode of loading the source data first and then loading the verification data is adopted, so that the loading process of the file system and the starting process of the service node are accelerated, the starting time of the service node under the abnormal condition is shortened, and the response efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of data storage, and in particular to an erasure code-based data recovery control method, device, device and medium. Background technique [0002] With the rapid development of the Internet, the widespread application of big data and cloud technology, the storage system needs to process more and more data. As a data storage medium, a disk has undergone several upgrades, and a single disk can store a larger amount of data. However, due to the increasingly complex storage environment, disks often come back online due to power failure or failure. [0003] At present, in order to use a small number of disks to store more data and achieve disaster recovery, erasure correction is usually used in the market to achieve data disaster recovery. However, in the process of data disaster recovery, because the impact of data reporting when the disk is powered on and data recovery when the disk is powered off o...
