Embodiment Construction

[0016] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The core idea of ​​the present invention is: considering that the scenes that need to add a hot spare disk after the RAID is created are mostly concentrated when the disk has a bad disk, the present invention selects that when the RAID detects a newly inserted disk at the bad disk, it will actively add it as Hot spare disk, that is, when any disk in the RAID is broken, when it is detected that a new disk is inserted in this position, the new disk is directly added to the hot spare disk of the RAID group without user setting. In this way, by automatically adding a new disk at the corresponding location to the RAID group when there is a bad disk, the scenarios that require the user to manually add a hot spare disk can be greatly reduc...

Abstract

The invention discloses an addition method and apparatus for a storage hot spare disk. The method comprises the steps of a, deleting a bad disk from member disks of an RAID when the bad disk is detected in the RAID; and b, according to a current hot spare disk configuration condition, when it is detected that the bad disk is pulled out and a new disk is inserted in the same position, setting the new disk as the hot spare disk, and performing automatic reconstruction on data in the bad disk. By adopting the method, the maintainability of the RAID can be improved.

Description

technical field [0001] The invention relates to storage technology, in particular to a method for adding a storage hot spare disk. Background technique [0002] In the current scheme of adding a hot spare disk for a Redundant Arrays of Independent Disks (RAID), the user adds the hot spare disk through the client, that is, the user needs to select the disk used as the hot spare disk in the client , and configure it as a hot spare disk for RAID. [0003] In practical applications, when a new disk is inserted into the RAID, the disk array cannot determine whether the new disk needs to be set as a hot spare disk. Therefore, it is necessary to rely on the user to manually operate the client to select the disk and set it as Hot spare disk. In this way, on the one hand, there needs to be a network environment on site, so that the client can interact with the disk array; on the other hand, the user also needs to master certain professional skills, understand basic storage knowledg...
