Embodiment Construction

[0064] The embodiment of the present invention provides an information processing method, which provides a fault handling scheme that can restore the performance and reliability of the hard disk group as soon as possible without changing the physical location of the member disks of the RAID group, and realizes At the same time, the performance and reliability of the hard disk group can be restored as soon as possible by reducing the occupied time of the hot spare disk.

[0065] In the embodiment of the present invention, when it is detected that there is a faulty member disk in the hard disk group, reconstruction of the hot spare disk is started; then when it is detected that the associated hot spare disk is inserted into the member disk slot of the faulty member disk, all The associated hot spare disk is identified as a member disk, and finally the incremental data is reconstructed to the identified member disk according to the incremental data bitmap, where the incremental da...

Abstract

The invention provides an information processing method and device. The information processing method comprises the steps that when it is detected that a disc member which breaks down exists in a hard disc set, a hot standby disc is started for reconstruction, so that data in the broken disc member are recovered into a relevant hot standby disc relevant to the broken disc member; when it is detected that the relevant hot standby disc is pulled out of a hot standby disc slot, an incremental data bitmap is established; when it is detected that the relevant hot standby disc is inserted into a disc member slot, the relevant hot standby disc is recognized to be a disc member; incremental data are reconstructed into the disc member according to the incremental data bitmap, wherein the incremental data bitmap is used for recording the position where the incremental data written into the broken disc member by a host computer are stored in the time period from the moment the relevant hot standby disc is pulled out of the hot standby disc slot to the moment the relevant hot standby disc is inserted into the disc member slot.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an information processing method and a processing device. Background technique [0002] In the prior art, a certain number of hard disks are grouped into RAID groups (English: Redundant Array of Independent Disks; Chinese: Redundant Array of Independent Hard Disks), and various RAID algorithms are used to improve data redundancy and read and write performance, so as to protect data and to optimize performance. When a hard disk in a RAID group fails, the data on the hard disk of the faulty member cannot be read or written, and the state of the RAID group changes from normal to degraded. At this time, the data can be restored to the hot spare disk through the RAID algorithm to restore the data The process is called refactoring. Among them, the hot spare disk is a hard disk configured in the RAID group to replace the hard disk of a failed member in time. After the rec...
