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
The present invention relates to electronic technology field, particularly relate to a kind of information processing method and treating apparatus.
Background technology
In prior art, the grouping of the hard disk of some is formed RAID group (English: Redundant Array ofIndependent Disks; Chinese: independent hard disk redundancy array), by using various RAID algorithm to improve data redundancy and readwrite performance, reach the object of protected data and Optimal performance.When the hard disk in RAID group breaks down, namely the data on fault member hard disk cannot be read and write, the state of RAID group from normally becoming degradation, now can by RAID algorithm by date restoring on HotSpare disk, recover the process of data and be called reconstruct.Wherein, HotSpare disk is the hard disk for replacing fault member hard disk in time configured in RAID group.After starting reconstruct, occupied HotSpare disk then becomes the dedicated hard disk of RAID group.If replace the fault member dish in RAID group with hard disk spare part, after waiting for that reconstruct completes, data can copy in spare part dish from HotSpare disk, and this data Replica process is called back to be copied.HotSpare disk can return copied after by RAID group discharge, in the system be made up of multiple RAID group, each RAID group is publicly-owned.
Prior art provides three kinds of reconstructing methods: HotSpare disk reconstructs, reconstruct and change dish reconstruct on the spot.HotSpare disk reconstruct is the most basic reconstruct mode, and when there being the member in RAID group to coil fault, the data of fault member hard disk are returned on HotSpare disk by RAID algorithm, and HotSpare disk is taken by RAID group, temporarily replaces the function of fault member dish.After fault member dish is replaced by spare part dish, starts back and copy, release HotSpare disk.And reconstruct the fault member dish first replaced with spare part dish in RAID group on the spot, more direct by data reconstruction in hard disk spare part.Changing dish reconstruct returns to the data of the fault member hard disk in RAID group on HotSpare disk by RAID algorithm, and HotSpare disk is taken by RAID group, becomes member's dish of RAID group after having reconstructed.
But HotSpare disk reconstruct, once start, needs to wait for that reconstruct could start back and copies after completing.In reconstruct with return in time period of copying, HotSpare disk continues to take by RAID group, and the reliability of whole array system reduces, and in system, other RAID groups occur that hard disk failure may can not find suitable HotSpare disk and go recovery data again.After reconstruct needs manual intervention spare part dish to replace fault member dish on the spot, could start and reconstruct on the spot.Be inserted into the slot of fault member dish at spare part dish before, RAID group keeps the state of demoting always, and the Performance And Reliability of the host service of its carrying reduces all greatly.Change dish reconstruct member to coil slot and there will be backstage and automatically change, be not suitable for and the situation that physical location planning fixes is coiled to the member of RAID group.
Therefore, also there is not the physical location of the member's dish neither changing RAID group in prior art, the performance of hard disk groups and the fault handling scheme of reliability can be recovered again as early as possible.

Below in conjunction with accompanying drawing, embodiments of the present invention are described in detail.
The embodiment of the present invention provides a kind of information processing method, is applicable to RAID group (English: RedundantArray of Independent Disks; Chinese: independent hard disk redundancy array); RAID group is formed the grouping of the hard disk of some; each hard disk in RAID group is called that member is coiled; by using various RAID algorithm can improve data redundancy and readwrite performance between each member dish, reach the object of protected data and Optimal performance.
Please refer to Fig. 1, the schematic diagram of the RAID that the information processing method that Fig. 1 provides for the embodiment of the present invention is suitable for.In Fig. 1, RAID group has 3 members dish: member coils 0, member coil 1 and member coil 2.If arbitrary member's dish breaks down in 3 member's dishes, can utilize the data in residue two member's dishes, by RAID algorithm, the date restoring in the fault member broken down being coiled out.Wherein, the rank of RAID group is RAID 5.
Please refer to Fig. 2, the process flow diagram of the information processing method that Fig. 2 provides for the embodiment of the present invention.Described method comprises:
Step 21: when detecting in hard disk groups that there is the fault member broken down coils, start HotSpare disk reconstruct, by the date restoring in described fault member dish to described fault member coil associate associate in HotSpare disk, wherein, described association HotSpare disk is arranged in HotSpare disk slot, and described fault member dish is arranged in member and coils slot;
Step 22: when detecting that described association HotSpare disk is pulled out from described HotSpare disk slot, creates incremental data bitmap;
Step 23: when detect described association HotSpare disk be inserted into described member coil slot time, described association HotSpare disk is identified as member dish;
Step 24: according to described incremental data bitmap, incremental data is reconfigured in described member dish, wherein, described incremental data bitmap to be inserted into described association HotSpare disk the moment between the insertion moment that described member coils slot from extracting of being pulled out from described HotSpare disk slot of described association HotSpare disk for recording, and main frame coils the memory location of the described incremental data of write to described fault member.
As a rule, after having member to coil in hard disk groups to break down, hard disk groups can start HotSpare disk reconstruct automatically, finds suitable HotSpare disk, date restoring in the fault member broken down being coiled is in HotSpare disk, and the HotSpare disk of the data of recovery of stomge is called the association HotSpare disk that fault member is coiled.The scheme that the embodiment of the present invention provides not only is applicable to disk, is also applicable to the solid state hard discs such as SSD.
Still please refer to Fig. 1, the member supposing in hard disk groups is coiled 1 and is broken down, then hard disk groups can start HotSpare disk reconstruct automatically, by member coil 0 and member coil 2 and the fault member broken down coiled date restoring in 1 in HotSpare disk 3.HotSpare disk 3 is called that fault member coils the association HotSpare disk of 1.
In the embodiment of the present invention, association HotSpare disk can be identified as member's dish by hard disk groups.In order to not change the physical location of member's dish, need the association HotSpare disk be positioned on HotSpare disk slot to extract, the member being then inserted into fault member dish coils slot.So, both complete date restoring, do not change again the physical location of member's dish of hard disk groups.
In prior art, the member being inserted into fault member dish at spare part dish is coiled after on slot, needs by the data Replica in HotSpare disk in spare part dish, and the data volume that needs copy is comparatively large, and the HotSpare disk occupied time is longer.In the embodiment of the present invention, in order to ensure association HotSpare disk be inserted into fault member dish member coil slot after, only need to recover the data that main frame writes in fault member dish during association HotSpare disk is pulled out, when detecting that association HotSpare disk is pulled out from HotSpare disk slot, incremental data bitmap can be created.Incremental data bitmap have recorded auto correlation HotSpare disk from HotSpare disk slot is pulled out the moment, and between the insertion moment that the member that extremely association HotSpare disk is inserted into fault member dish coils slot, main frame coils the position of the incremental data of write to fault member.
When detecting that association HotSpare disk is inserted into the slot of fault member dish, association HotSpare disk is identified as member's dish of hard disk groups by hard disk groups, and incremental data is returned in the member's dish identified.Particularly, utilize the data in the member's dish do not broken down and incremental data bitmap, can incremental data be recovered by RAID algorithm.
In the embodiment of the present invention, according to detect association HotSpare disk be inserted into fault member dish member slot dish time the insertion moment, the date restoring state of hard disk groups, has following three kinds of embodiments.
The first embodiment: detect association HotSpare disk be inserted into fault member dish member slot dish time the insertion moment, hard disk groups just HotSpare disk reconstruct process in, HotSpare disk reconstruct not yet complete.That is, in the process of hard disk groups HotSpare disk reconstruct, association HotSpare disk is inserted into the member slot dish of fault member dish.
Under the first embodiment, after execution of step 24, can also following steps be performed:
Determine the reconstruct progress that described HotSpare disk reconstructs, extract the moment described in described reconstruct progress is characterized in, the data volume in described association HotSpare disk accounts for the ratio of the data volume in described fault member dish;
Only have partial data to be reconfigured in described association HotSpare disk if described reconstruct progress characterizes in described fault member dish, then the remaining data except described partial data in described fault member dish is reconfigured in described member dish.
For example, as a rule, after having member to coil in hard disk groups to break down, hard disk groups can start HotSpare disk reconstruct automatically, find suitable HotSpare disk, date restoring in the fault member broken down being coiled is in HotSpare disk, if in the process of hard disk groups HotSpare disk reconstruct, association HotSpare disk is extracted by from HotSpare disk slot, then HotSpare disk reconstruct can suspend, data in fault member dish only have partial data to return in association HotSpare disk, when associating HotSpare disk and being inserted into the slot of fault member dish, association HotSpare disk is identified as member's dish, remaining data in then fault member being coiled returns in the member's dish identified.
Still please refer to Fig. 1, the member supposing in hard disk groups is coiled 1 and is broken down, then hard disk groups can start HotSpare disk reconstruct automatically, according to RAID redundant arithmetic utilize member coil 0 and member coil 2 and the fault member broken down coiled date restoring in 1 in HotSpare disk 3.HotSpare disk 3 is called that fault member coils the association HotSpare disk of 1.In the process of HotSpare disk reconstruct, HotSpare disk 3 is extracted by from HotSpare disk slot, then HotSpare disk reconstruct can suspend, member's data of coiling in 1 only have partial data to return in HotSpare disk 3, as shown in Figure 3A, member is coiled in 1 only has partial data to return in HotSpare disk 3, represents the partial data returned in HotSpare disk 3 in Fig. 3 A with dash area.HotSpare disk 3 be inserted into member coil the slot of 1 time, HotSpare disk 3 be identified as member dish, can then by member the remaining data coiled in 1 return to identify member dish in.
When HotSpare disk 3 is extracted from HotSpare disk slot, also incremental data bitmap can be created.As shown in Figure 3 B, be pulled out period at HotSpare disk, namely HotSpare disk 3 is extracted the moment by what extract from HotSpare disk slot, and be inserted into HotSpare disk 3 member that member coils 1 and coil between slot, the data that main frame coils 1 write to member are called incremental data.In Fig. 3 B, member coil 0 and the blockage that coils in 2 of member namely represent incremental data.The memory location of incremental data can be created, be called incremental data bitmap.Form in Fig. 3 B is incremental data bitmap.
HotSpare disk 3 be inserted into member coil the slot of 1 time, HotSpare disk 3 be identified as member dish, not only can then by member the remaining data coiled in 1 return to identify member dish in, also incremental data can be returned to identify member dish in.As shown in Figure 3 C, HotSpare disk 3 is positioned at member and coils on the slot of 1, not only incremental data is returned in HotSpare disk 3, and also returned to by remaining data in HotSpare disk 3, in fig. 3 c, the non-shaded portion in HotSpare disk 3 represents remainder data.
The second embodiment: detect association HotSpare disk be inserted into fault member dish member slot dish time the insertion moment, hard disk groups completed HotSpare disk reconstruct.That is, after hard disk groups HotSpare disk has reconstructed, association HotSpare disk has been inserted into the member slot dish of fault member dish.
Under the second embodiment, step 23 is specially:
Detecting that described fault member dish to coil from described member after slot extracts, judging that described member coils whether the hard disk that first time on slot inserts is described association HotSpare disk;
If yes, then described association HotSpare disk is identified as member's dish.
For example, as a rule, after having member to coil in hard disk groups to break down, hard disk groups can start HotSpare disk reconstruct automatically, find suitable HotSpare disk, date restoring in the fault member broken down being coiled is in HotSpare disk, if in the process of hard disk groups HotSpare disk reconstruct, association HotSpare disk is extracted by from HotSpare disk slot, then HotSpare disk reconstruct can suspend, data in fault member dish only have partial data to return in association HotSpare disk, when associating HotSpare disk and being inserted into the slot of fault member dish, association HotSpare disk is identified as member's dish, remaining data in then fault member being coiled returns in the member's dish identified.
Still please refer to Fig. 1, the member supposing in hard disk groups is coiled 1 and is broken down, then hard disk groups can start HotSpare disk reconstruct automatically, by member coil 0 and member coil 2 and the fault member broken down coiled date restoring in 1 in HotSpare disk 3.HotSpare disk 3 is called that fault member coils the association HotSpare disk of 1.After HotSpare disk has reconstructed, member's total data of coiling in 1 has returned in HotSpare disk 3, and as shown in Figure 4 A, member is coiled total data in 1 and returned in HotSpare disk 3, represents the data returned in HotSpare disk 3 in Fig. 4 A with dash area.HotSpare disk 3 be inserted into member coil the slot of 1 time, HotSpare disk 3 is identified as member's dish, only needs incremental data to return in the member's dish identified.
HotSpare disk 3 be inserted into member coil the slot of 1 time, HotSpare disk 3 is identified as member's dish, because HotSpare disk reconstruct completes, so only need incremental data to return in the member's dish identified.As shown in Figure 4 B, HotSpare disk 3 is positioned at member and coils on the slot of 1, only needs incremental data to be returned in HotSpare disk 3, and in figure 4b, the dash area in HotSpare disk 3 represents that member coils the total data in 1.
In above-mentioned two kinds of embodiments, described described association HotSpare disk is identified as member's dish after, described method also comprises: when detecting that spare part dish is inserted into described HotSpare disk slot, and described spare part dish is set to HotSpare disk.
Specifically, after association HotSpare disk being identified as member's dish, spare part dish can be inserted into the HotSpare disk slot of association HotSpare disk, namely spare part dish becomes HotSpare disk.Such as: be inserted into by HotSpare disk 3 after member coils the slot of 1, HotSpare disk 3 is identified as member's dish, and now, spare part dish can be inserted into the HotSpare disk slot of HotSpare disk 3, namely spare part dish becomes HotSpare disk.
The third embodiment: detect association HotSpare disk be inserted into fault member dish member slot dish time the insertion moment, hard disk groups is carrying out back copying.That is, return in hard disk groups in the process copied, association HotSpare disk is inserted into the member slot dish of fault member dish.
Under the third embodiment, step 23 is specially:
Detecting that described fault member dish to coil from described member after slot extracts, judging that described member coils whether the hard disk that first time on slot inserts is spare part dish;
If yes, then start back and copy, by the data Replica in described fault member dish in described spare part dish;
In the process to copy for described time, exchange described spare part dish and the described position associating HotSpare disk, described association HotSpare disk is inserted into described member and coils slot, and described spare part dish is inserted into described HotSpare disk slot;
Described association HotSpare disk is identified as member's dish.
Under the third embodiment, described described association HotSpare disk is identified as member's dish after, described method also comprises: described spare part dish is set to HotSpare disk.
For example, as a rule, after having member to coil in hard disk groups to break down, hard disk groups can start HotSpare disk reconstruct automatically, finds suitable HotSpare disk, and the date restoring in the fault member broken down being coiled is in HotSpare disk, after HotSpare disk has reconstructed, if member spare part dish being inserted into fault member dish coils slot, then hard disk groups can heavily be copied in automatic startup, by the date restoring in HotSpare disk in spare part dish.Due to the data that the data in HotSpare disk are in fault member dish, data volume is large, returns to copy needs and take a long time.So can by association HotSpare disk and spare part dish switch, the member that association HotSpare disk is inserted into fault member dish is coiled slot, and spare part dish is inserted into the HotSpare disk slot of association HotSpare disk, so, be inserted in the association HotSpare disk on member's dish of fault member dish the data stored in fault member dish, only need incremental data, namely associate HotSpare disk be pulled out period main frame be written to fault member dish in date restoring to association HotSpare disk in.Meanwhile, because spare part dish is inserted into the slot of association HotSpare disk, so spare part dish can be set to HotSpare disk.
Still please refer to Fig. 1, the member supposing in hard disk groups is coiled 1 and is broken down, then hard disk groups can start HotSpare disk reconstruct automatically, by member coil 0 and member coil 2 and the fault member broken down coiled date restoring in 1 in HotSpare disk 3.HotSpare disk 3 is called that fault member coils the association HotSpare disk of 1.After HotSpare disk has reconstructed, member's total data of coiling in 1 has returned in HotSpare disk 3, and as shown in Figure 5A, member is coiled total data in 1 and returned in HotSpare disk 3, represents the data returned in HotSpare disk 3 in Fig. 5 A with dash area.Spare part dish 4 be inserted into member coil the slot of 1 time, hard disk groups can heavily be copied in automatic startup, by the data Replica in HotSpare disk 3 in spare part dish 4.Show the data copied in spare part dish 4 with black part submeter in Fig. 5 A.
In the process heavily copied, HotSpare disk 3 and spare part dish 4 switch, HotSpare disk 3 is inserted into the slot that member coils 1, spare part dish 1 is inserted into the HotSpare disk slot of HotSpare disk 3, HotSpare disk 3 be inserted into member coil the slot of 1 time, HotSpare disk 3 is identified as member's dish, only needs incremental data to return in the member's dish identified.
HotSpare disk 3 be inserted into member coil the slot of 1 time, HotSpare disk 3 is identified as member's dish, because HotSpare disk reconstruct completes, so only need incremental data to return in the member's dish identified.As shown in Figure 5 B, HotSpare disk 3 is positioned at member and coils on the slot of 1, only needs incremental data to be returned in HotSpare disk 3, in figure 5b, dash area in HotSpare disk 3 represents that member coils the total data in 1, and spare part dish 4 is positioned on the slot of HotSpare disk 3, is set to HotSpare disk.
In above-mentioned three kinds of embodiments, step 23 is specially:
