Problems solved by technology

The I / O process of the storage system is complex, and a large number of exception handling scenarios intersect with each other. At the same time, large loads and multi-threading are key scenarios that cause data inconsistency. The positioning cost of data inconsistency is huge, not only occupying storage computing resources Performance, the log method will also occupy a large amount of storage space, and a large number of log reads and writes will slow down the system I / O processing performance
It is more complicated to locate data inconsistencies at the customer site, and the most commonly used method is to rely on logs

Embodiment

[0046] First of all, when the consistency check module is initialized, a certain amount of memory space will be allocated in the memory for saving the consistency check information. Note that the amount of memory space allocated here is proportional to the size of the consistency check data.

[0047] Secondly, the consistency verification module provides a grainSize granular data consistency verification information recording interface based on the thin volume of the storage system. When the data is placed on the disk, it will record the consistency check information of the data, first calculate the fingerprint value of the data, obtain the PBA of the data after the disk is placed, record the time stamp and other information, and maintain this information through the hash list.

Abstract

The present invention provides a method and device for data analysis. The method includes the following steps: allocating a memory space with a preset storage amount in the memory; to the memory space; in response to receiving an instruction on the operation of the data, read the verification information stored in the disk; compare the verification information read from the disk with the verification information stored in the memory space; respond to the comparison If the results are inconsistent, the memory storage information is stored in the disk, and the memory storage information is parsed to analyze the cause of the data inconsistency. By using the method of the invention, the cause of data inconsistency can be quickly and effectively analyzed, the occupancy of system computing resources is reduced, the efficiency is improved, the access speed of consistent information is improved, and the performance of the whole machine is improved.

Description

technical field [0001] This field relates to the field of computers, and more particularly to a method and device for data analysis. Background technique [0002] The storage system is the container that carries the user's production data, and at the same time it is the fusion of efficient data utilization and disaster recovery backup. In today's rapid development of data, it is the most basic and most important of the storage system to ensure the integrity and safety of the user's data. a bottom line. The I / O process of the storage system is complex, and a large number of exception handling scenarios intersect with each other. At the same time, large loads and multi-threading are key scenarios that cause data inconsistency. The positioning cost of data inconsistency is huge, not only occupying storage computing resources Performance, the log method will also occupy a large amount of storage space, and a large number of log reads and writes will slow down the system I / O pro...
