Abstract

The invention provides a disk reconfiguration method based on a RAID and a related apparatus. The disk reconfiguration method comprises the steps that distribution of priorities is conducted on services, then the services are stored in disk blocks, due to different service priorities of the services stored in the disk blocks, when reconfiguration is conducted, the disk blocks with the higher service priorities are preferably selected to be reconfigured, data corresponding to the services with the higher service priorities can be reconfigured in time, and the problem that due to the fact that key recovery data are lost when a disk is abnormal, a system has a fault and cannot be recovered is solved.

Description

technical field

[0001] The invention relates to the storage field, in particular to a RAID-based disk reconfiguration method and related equipment. Background technique

[0002] RAID technology is a technology that combines multiple independent disks or hard disks to form a disk group or hard disk group, also known as a logical disk, to provide higher storage performance and data processing capabilities than a single disk. A disk group Multiple disks in the cluster are member disks.

[0003] According to different combinations of disks, RAID can be divided into different levels, such as RAID0, RAID10, RAID3, RAID5, RAID6, etc. Different RAID levels provide different data protection schemes. Among them, RAID3, RAID5, and RAID6 all provide data redundancy protection function, that is, when one disk in the disk group fails (RAID6 allows 2 disks), the data of the faulty disk can be calculated through the data on the normal disk and the parity check. So as to ensure the normal...
