Disk-based data migration method and apparatus, and electronic device

Abstract

The invention discloses a disk-based data migration method and apparatus, and an electronic device. The method comprises the steps of obtaining disk attribute information of a disk, and providing thedisk attribute information for a preset disk fault model; obtaining an output result of the disk fault model, and according to the output result, judging whether the disk meets a preset data migrationcondition or not; and if yes, according to a preset data migration policy, executing data migration operation on stored data. In the way, the fault information of the disk can be predicted in advance, and the stored data in the disk can be actively migrated before the disk has a fault, so that the situation of data loss caused by the fault of the disk is effectively avoided; and in addition, thepreset disk fault model can predict the fault information of various types of disks, so that the applicability is wide.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a data migration method, device and electronic equipment based on a disk. Background technique [0002] With the increasing popularity of network services, the number of user visits is increasing, and correspondingly a large amount of business data will be generated. Business data is crucial to each network service, so the business data is stored in the disk to facilitate its processing and utilization. However, a disk failure will result in the loss of business data and affect the operation of network services. For example, for online services, many online services rely on local business data. If a disk fails, these online network services will inevitably be abnormal, or even unable to provide services. [0003] However, the inventor found in the process of implementing the present invention that there are at least the following defects in the prior art: the data in the disk ...

However, a disk failure will result in the loss of business data and affect the operation of network services. For example, for online services, many online services rely on local business data. If a disk fails, these online network services will inevitably be abnormal, or even unable to provide services

[0003] However, the inventor found in the process of implementing the present invention that there are at least the following defects in the prior art: the data in the disk can only be backed up in advance to prevent data loss, even if the disk is found in the daily inspection. Symptoms of failure, for example, through the fields in the log data, it is possible to determine in advance that the disk will fail and the time of failure, and only passively wait for the disk to fail, and then repair the data in the disk by querying the backup, for example, for The data of multiple copies is saved. During the process of reading data or inspection, if a disk failure is found, the data lost due to disk failure will be copied from the copy.

This shows, lacks a kind of method that can solve the above problem well in the prior art
