Abstract

The invention discloses a data processing method and device based on multiple verification and a storage medium. The method includes: acquiring a data reading instruction, and reading first copy information from a first target node according to the reading instruction, wherein the first copy information includes first copy data and a first checksum corresponding to the first copy data; extractingthe first copy data from the first copy information, and generating a second checksum according to the first copy data; reading second copy information from a second target node when the first checksum and the second checksum do not meet a first preset condition; and comparing the second copy information and the first copy information, and adjusting the first copy information according to a comparison result. According to the method, checksum misjudgment can be effectively detected and avoided through multiple verification on multiple copies, precision of using the checksums to detect data errors can be improved, and negative impacts on a system can be reduced.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data processing method, device and storage medium based on multiple verifications. Background technique [0002] Maintaining data integrity is the most important responsibility of modern storage systems, so various techniques have been developed and applied to improve data integrity protection. The most commonly used and popular of these is the checksum method. Traditional checksum methods for storage systems are generally classified into two categories, one is end-to-end checksum, and the other is disk checksum. In general, when using checksums to protect data, once the data changes abnormally, the recalculated checksums at the time of reading are not equal to the checksums calculated at the time of storage. However, the checksum itself will also have errors, and because the checksum and data writing are not synchronized during the writing process, other acce...
