Abstract

The invention discloses a method and device for determining consistency among multiple storage object copies, electronic equipment, a readable storage medium and a computer program product, and relates to the technical field of cloud storage. The method comprises steps: determining a plurality of data segments included in a storage object copy; carrying out hash operation on at least one data segment in the plurality of data segments to obtain hash data corresponding to the data segment, and after the hash operation is executed, switching a storage object copy subjected to the hash operation at this time from a locked state to an unlocked state; and determining the consistency among the plurality of storage object copies according to the consistency of the hash data of the corresponding data segments among the plurality of storage object copies corresponding to the same original object. According to the scheme, the situation that due to the fact that consistency verification is conducted on the storage object copy with the large data size at a time, the time for holding the lock after the storage object copy is locked is long is avoided, and the flexibility of consistency verification is improved.

Description

Technical field [0001] The present application relates to the field of computer technology, and more particularly to cloud storage techniques, a method, apparatus, electronic device, readable storage medium, and computer program product that determines the consistency between multiple memory object copies. Background technique [0002] Due to disk silence errors or vulnerabilities exist in the software itself, it may result in inconsistencies between the copass data in the distributed storage system. The distributed storage system needs to schedule each copy data periodically, and the copies data is hash calculations to determine whether each copy data is consistent, and the inconsistent copies are repaired. The copy data is required to lock the copy data during the scan data for hash calculations. Inventive content [0003] This application provides a method, apparatus, electronic device, readable storage medium, and computer program product that determines the consistency betw...
