Description
Technical field
The present invention relates to electronic technology field, more particularly, to a kind of information processing method and processing meanss.
Background technology
In prior art, a number of hard disk is grouped and forms raid group (English: redundant array of
independent disks；Chinese: independent hard disk redundancy array), to improve data redundancy by using various raid algorithm
And readwrite performance, the purpose reaching protection data and optimizing performance.When the hard disk in raid group breaks down, fault member is hard
Data on disk cannot be read and write, and the state of raid group, now can be by raid algorithm by data from being normally changed into degrading
Return on HotSpare disk, the process recovering data is referred to as reconstructing.Wherein, HotSpare disk is to configure in raid group for timely replacement
The hard disk of fault member's hard disk.After starting reconstruct, occupied HotSpare disk then becomes the dedicated hard disk of raid group.If using hard disk
The fault member disk in raid group replaced by spare part, and after waiting reconstruct to complete, data can copy in spare part disk from HotSpare disk,
This data duplication process is referred to as back copying.HotSpare disk can return copy after the completion of by raid group release, be made up of multiple raid groups
In system, each raid group is publicly-owned.
Prior art provides three kinds of reconstructing methods: HotSpare disk reconstructs, reconstructs on the spot and change disk reconstruct.HotSpare disk reconstructs
It is most basic reconstruct mode, when there being the member disk fault in raid group, the data of fault member's hard disk is calculated by raid
Method returns on HotSpare disk, and HotSpare disk is taken by raid group, temporarily replaces the function of fault member disk.When fault member disk is changed
After spare part disk, start back and copy, discharge HotSpare disk.And reconstruct on the spot and first replace the fault member disk in raid group with spare part disk,
Again directly by data reconstruction in hard disk spare part.Change disk reconstruct the data of the fault member's hard disk in raid group is calculated by raid
Method returns on HotSpare disk, and HotSpare disk is taken by raid group, and reconstruct becomes the member disk of raid group after completing.
But, HotSpare disk reconstruct, once starting, needs wait reconstruct could start back after completing and copies.Copy reconstructing and returning
Time period in, HotSpare disk is persistently taken by raid group, and the reliability of whole array system reduces, and in system, other raid groups are again
Appearance hard disk failure may can not find suitable HotSpare disk and go to recover data.Reconstruct needs manual intervention spare part disk to replace on the spot
After fault member disk, could start and reconstruct on the spot.Before spare part disk is inserted into the groove position of fault member disk, raid group is protected always
Hold the state of degradation, the Performance And Reliability of the host service that it carries all substantially reduces.Change disk reconstruct member's dish groove position can go out
Existing backstage is changed automatically, is not suitable for the situation fixing to the member disk physical location planning of raid group.
