US 2025/0061235 A1 · METHOD AND APPARATUS FOR DATA CONSISTENCY DETECTION AND REPAIR, AND MEDIUM

Abstract

This present disclosure discloses a method and apparatus for data consistency detection and repair, and a non-transitory computer-readable storage medium, related to the technical field of storage. In the method, consistency detection is performed on files; and when it is detected that the files are inconsistent, the files are repaired. In the repair process, data objects of a file to be repaired are acquired, and data objects to be repaired is determined; and the data objects to be repaired are then repaired according to copy data corresponding to the data objects. Hence, in the method, check information does not need to be attached to the entire IO path during implementation of data consistency, and therefore it is easier to implement data consistency; next, it is first determined whether files are consistent, then only a file to be repaired is divided into a plurality of data objects, and files satisfying data consistency do not need to be divided into a plurality of data objects, thereby reducing the time for determining a data object to be repaired, simplifying the process of data consistency detection and repair, and improving the efficiency of data consistency detection and repair.

Dependent claims

A method for data consistency detection and repair, comprising:

acquiring a current file and an original file corresponding to the current file;
comparing the current file with the original file, so as to determine whether the current file is consistent with the original file;
determining, when the current file is inconsistent with the original file, that the current file is a file to be repaired:
acquiring data objects of the file to be repaired;
comparing the data objects of the file to be repaired with data objects of the original file, so as to determine a data object to be repaired;
and repairing, according to copy data of the data objects of the original file, the data object to be repaired, and returning to the operation of acquiring the current file and the original file corresponding to the current file;
and
ending the process when the current file is consistent with the original file.
