Problems solved by technology

However, with this existing processing method, some data on the failed disk will be lost, for example, the data in the area corresponding to the unreadable area on the failed disk will be lost, resulting in incomplete disk data after reconstruction

Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] The terms "disk" and "hard disk" involved in this embodiment of the present invention have basically the same meaning. The disk is a device disk that can read and write through magnetism. It can be a non-volatile storage medium, and the saved files will not be lost after power failure. The hard disk is to put the storage pieces of the disk into a hard metal box to get better protection.

[0047] The disk reconstruction involved in the embodiment of the...

Abstract

Provided is a disk reconstruction method. The method comprises: when a fault exists in a first member disk in a redundant array of independent disks (RAID) group, restoring data of the first member disk according to data of a second member disk other than the first member disk in the RAID group, and storing the restored data in a target disk; before the fault recoveryof the first member disk, replacing the first member disk with the target disk containing the restored data as a member disk in the RAID group (S105); and after the fault recoveryof the first member disk, performing corresponding reconstruction processing according to the restored first member disk (S107). Also provided is a disk reconstruction device. The method and device can reduce data loss and quickly restore a service of a user.

Description

technical field [0001] The invention relates to the field of storage, in particular to a disk reconfiguration method and device thereof. Background technique [0002] Redundant Array of Independent Disks (RAID), formerly known as Redundant Array of Inexpensive Disks (RAID), is a disk group or hard disk group formed by combining multiple independent disks or hard disks, which can also be called logical hard disk. Multiple disks in a disk group are mutual member disks. [0003] RAID technology is one of the most commonly used technologies in the storage field. It virtualizes multiple disks or hard disks into a large-capacity disk or hard disk. It can speed up the overall storage speed through parallel reading and writing, and can use redundant error correction technology to achieve certain fault tolerance, thus providing higher storage performance and data backup capability than a single disk or hard disk of the same capacity. [0004] In the prior art, after a certain disk...
