Kind RAID combinations, are identified, such as RAID-0, RAID-1, RAID-1E, RAID-5, RAID-6, RAID-7 with RAID level,
RAID-10, RAID-50.Different grades of recovery and Preservation tactics may be implemented in different RAID level, meet performance and safety
A variety of needs.The number of hard disk and storage mode needed for various RAID level are known to the public, repeat no more.
Redundant array of independent disks abbreviation disk array RAID, by the way that the independent hard disk of polylith (physical hard disk) is pressed difference
Mode combines to form a hard disk groups (logic hard disk), to provide storage performance more higher than single hard disk and provide number
According to the technology of redundancy.RAID carries out subregion in entire array to data, and extensive by hard disk parity data offer data
Multiple function.It, can be according to other hard in parity data and array when a hard disk is broken down due to generation bad track
Data on disk calculate data lost in faulty hard disk bad track, to carry out bad track reparation.Wherein, can have in RAID
The storage region of multiple hard disks, memory capacity, such as 64k, 128k that several contiguous sectors are constituted etc. is properly termed as one point
Item, the memory capacity that several continuous magnetic tracks are constituted, such as the storage region of 64M are properly termed as a data block (Chunk), across
The relevant data block of logical place of all hard disks is properly termed as a band more in RAID groups, and wherein logical place correlation can be with
Think that the number of the data block being located in same band in a hard disk is identical, but physical location in a hard disk is not necessarily identical.
Illustratively, Fig. 1 provides a kind of structural schematic diagram of RAID-5, and related data is stored in the difference of same band by RAID-5
Upper, including user data and the verification data of hard disk, such as user data can be stored in hard disk 1 to hard disk 4 and be located at item
It, can be by user data according to checking algorithm (such as exclusive or) as shown in the D1 in Fig. 1 in the data block for being 1 with the number in 1
In the data block that the number that the verification data that calculating obtains is stored in hard disk 5 is 1, as shown in the P1 in figure.In same band
In, a data data in the block can be obtained by the data data in the block of other hard disks by checking algorithm, thus its
Its data data in the block are properly termed as the associated redundant data of data in current data block.Certainly, in the embodiment of the present invention
Storage array is not limited in RAID-5.
The embodiment of the present invention can also be applied to the storage system of the miscellaneous equipments such as low, middle-end storage array or server
In, the embodiment of the present invention does not limit.
Hard disk failure generally follows following rule:If a certain sector of hard disk generates bad track, adjacent contiguous sector
The possibility for generating bad track is big, such as may lead to scratch continuous multiple sectors productions in region magnetic sheet due to being scratched etc.
Raw bad track;If the bad track of unrepairable occur in multiple sectors in hard disk, the possibility of hard disk failure is big.
In the prior art, when any sector generates bad track in hard disk, bad track of hard disk will not be reported immediately, but works as upper layer
When host service accesses current sector, hard disk can just detect the bad track by itself testing mechanism, to report the bad track
To such as controller of the fault treating apparatus in storage array.The judgment mechanism whether hard disk fails can there are many, it is exemplary
Can consider that hard disk fails when the sector for generating bad track reaches certain quantity, or when the components such as magnetic head in hard disk damage
Bad when, can consider that hard disk fails, and when upper layer host business is detected hard disk (such as booting detection), hard disk just meeting
It reports hard disk to fail, thus hard disk failure is reported to equally exist delay.That is, hard disk reporting fault has delay, here
Failure may include reporting bad track of hard disk and hard disk being reported to fail.
The embodiment of the present invention provides a kind of processing method of hard disk failure, and referring to Fig. 2, step may include mainly:
201, device receives the fault message that hard disk reports, and fault message includes the address information for the sector for generating bad track,
And record the address information of sector.
Wherein, device here is the processing unit of hard disk failure, such as can be the controller in storage array.
Due to spread of voltage, abnormal shutdown, high temperature, the reasons such as vibrations, may lead to the sector in hard disk when read-write
It cannot normally be accessed or cannot normally be read and write, i.e., hard disk generates bad track.The device can be by storing in other hard disks
Associated redundant data carries out bad track reparation, to reconstruct the slitting where generating the sector or sector of bad track to when front disk
In hot standby region, loss of data is prevented.Wherein, since sector is to be divided into the memory capacity of hard disk according to storage address
The storage region of 512 bytes, thus, illustratively, the sector institute for generating bad track can be recorded by records storage address
Position.For example, when upper layer host business reads the data in bad track, hard disk is reported for the first time by itself testing mechanism
When generating the sector of bad track, the address information recording of the sector can be got off, in order to pass through the sector progress to the position
Scanning Detction determines if to generate bad track again.
202, after device is repaired successfully in sector, sector is scanned according to address property information cycle, determines sector
Whether after repairing successfully bad track is generated again.
For the sector after being repaired successfully in step 201, periodically the sector can be scanned, such as can be into
Row reads (read) scanning, if can normally be read in read scanning processes, shows that the sector is normal, does not generate again bad
Road;If cannot normally read, show that the sector generates bad track again.Periodicity therein refers to, can to it is any generate it is bad
Road is simultaneously repaired one time cycle of successful sector settings, and respectively to any fan for generating bad track after being spaced the specified time
Area carries out periodic scan, or to all generation bad tracks and can also repair successful sector settings period at the same time,
And after being spaced the specified time, periodic scan is carried out successively to all sectors for generating bad track.
It is of course also possible to including to the slitting where the sector of generation bad track or the sector including currently generating bad track
The region that multiple contiguous sectors are constituted is scanned, and the embodiment of the present invention does not limit the specific range of scanning.
It should be noted that if determining that current sector does not generate bad track again after repairing successfully, then can wait for down
The Scanning Detction in one period, to determine whether current sector generates bad track again.
The embodiment of the present invention to generating bad track and repairing successful sector and be scanned by periodically actively determining
Whether the sector generates bad track again, can find bad track in time, avoids hard disk in the prior art and needs to wait for upper layer host
Business could carry out itself detection when reading the bad track, there are problems that delay so as to cause reporting fault.
If 203, the number of sector generation bad track reaches frequency threshold value, device carries out data to the data block where sector
Reconstruct.
Wherein, the frequency threshold value in this step can be 2,3 or other values, can specifically be set according to actual conditions,
The embodiment of the present invention does not limit.Due to hard disk it is a certain generate bad track sector near sector may also often will produce it is bad
, that is, there is potential bad track in road, such as may cause to scratch due to being scratched etc. magnetic sheet including region includes current bad track
Continuous multiple sectors generate bad tracks.If the number that sector generates bad track reaches frequency threshold value, illustrate that current sector generates again
The possibility of bad track is big, and the poor reliability of current sector, the sector adjacent with current sector is iteratively produced the possibility of bad track
Greatly, thus can be by the data block where current sector, i.e., nearby continuous multiple sectors carry out data reconstructions for current sector, keep away
Exempt from the data potential bad track in the block and causes loss of data.Illustratively, when the frequency threshold value is 2, that is, current sector is determined
Bad track is generated again after first time repairs successfully, that is to say, that, can be to sector institute when second of the generation bad track in current sector
Data block carry out data reconstruction.
Optionally, carrying out data reconstruction to the data block where sector may include:By the data block migration where bad track
The clear area of other hard disks to the clear area of this hard disk or in addition to this hard disk, and data block in isolation hard disk.
Wherein, the data block in hard disk is isolated, can refers to the mapping pass for cancelling upper layer host business with the data block
System, so, upper layer host business will not be written and read operation to the data block again, i.e., the data block will be no longer used.
In addition, carrying out data reconstruction to the data block where sector can also include, according to the migration position of data block where bad track, weight
New structure redundancy check data, to constitute redundancy relationship with the data in other hard disks.
The embodiment of the present invention carries out data reconstruction by the data block where the sector to generating bad track again, can be timely
Restore the data in bad track, avoids in the prior art since present hard discs reporting fault has delay, if before reporting fault
The other hard disks for storing associated redundant data in current bad track or the potential bad track of data block also break down, then in this bad track of hard disk
Data the problem of can not restoring, you can, cannot be in time to hard to solve in the prior art since hard disk reporting fault has delay
Hard disc data is lost caused by disk failure is handled so that the problem of storage system poor reliability.
The embodiment of the present invention provides a kind of processing method of hard disk failure, by periodically to generate bad track and repair at
The sector of work(is scanned, and determines whether the sector generates bad track again, can be found bad track in time, be avoided in the prior art
Hard disk needs that itself detection could be carried out when upper layer host business being waited for read the bad track, exists so as to cause reporting fault and postpones
The problem of;Data reconstruction is then carried out by the data block where reaching the sector of frequency threshold value to the number for generating bad track, it can
To restore to avoid in the prior art due to working as there are the data in the sector of potential bad track in current sector and data block in time
Preceding hard disk reporting fault has delay, if storing relevant redundancy in the bad track of current bad track or current data block before reporting fault
The problem of other hard disks of data also break down, then the data in this bad track of hard disk can not be restored, you can to solve existing skill
Since hard disk reporting fault has delay in art, hard disc data is lost caused by cannot handling in time hard disk failure, makes
The problem of obtaining storage system poor reliability.
The embodiment of the present invention will be described the processing method of hard disk failure by taking RAID-5 shown in Fig. 1 as an example, ginseng
See Fig. 3, may include following key step:
301, device receives the fault message that hard disk reports, and fault message includes the address information for the sector for generating bad track,
And record the address information of sector.
Wherein, device here is the processing unit of hard disk failure, such as can be the controller in storage array.
Due to spread of voltage, abnormal shutdown, high temperature, many reasons such as vibrations, may cause in hard disk when read-write
Sector generates bad track.Bad track reparation can be carried out by the associated redundant data stored in other hard disks by generating the hard disk of bad track,
To restore the data in bad track, loss of data is prevented.Wherein, when upper layer host business reads the data in bad track, hard disk
By itself testing mechanism, when reporting the sector for generating bad track for the first time, the sector position for generating bad track can be recorded below
Storage address information determines if to generate bad track again in order to be detected by the sector to the position.
Illustratively, in step 301, carrying out bad track reparation to the sector A for generating bad track in the data block of hard disk 1 can be with
The hot standby sector for specifying a certain sector B to be used as sector A by rebuilding mapping relations in the hot standby region of present hard discs, and
According to the associated redundant data and checking algorithm (such as exclusive or algorithm) in other hard disks in the B of sector, restores current and generate
Data in the sector of bad track simultaneously rebuild data redundancy relationship.After rebuilding mapping relations, the sector B in hot standby region
The sector A being remapped in data block 1.Meanwhile cancelling reflecting for upper layer host business and the sector A in former data block 1
Relationship is penetrated, upper layer host business will not be written and read operation to the sector A in former data block 1 again, i.e., sector A in former data block 1
It is isolated and is no longer used.
Wherein, the sector near the sector of bad track is generated since hard disk is a certain to will also tend to generate bad track, it is possible to exist
Potential bad track, such as it includes continuous more including current bad track that may lead to scratch region magnetic sheet due to being scratched etc.
A sector generates bad track.Thus, when the sector A in hard disk generates bad track, the contiguous sector near the A of sector also generates bad track
Possibility is big, when carrying out bad track reparation by the hot standby region of hard disk, can carry out data reconstruction to the sector A for generating bad track,
Can also be to multiple contiguous sectors near the A of sector, such as slitting where the A of sector carries out data reconstruction, the embodiment of the present invention
It does not limit.
In addition, due to other hard disk failures or associated redundant data loss etc., for generating bad track and repairing failure
Sector, it is believed that the sector unrepairable, and bad block label (Bad Sector Tag, BST) is carried out to the sector, to
It abandons using the sector.
302, after sector is repaired successfully, device is scanned sector according to address property information cycle, determines sector
Whether after repairing successfully bad track is generated again.
For the sector after being repaired successfully in step 301, illustratively, can be determined according to the storage address information of record
It generates bad track and repairs the position of successful sector, (be actually periodically then to be mapped as fanning in hot standby region to sector A
The position of the sector B of area A) carry out read scannings show that the sector is normal if can normally be read in read scanning processes,
Bad track is not generated again;If cannot normally read, show that the sector generates bad track again.Periodicity therein refers to, can
It is right respectively to any generation bad track and to repair one time cycle of successful sector settings, and after being spaced the specified time
Any sector for generating bad track carries out periodic scan, or can also to all sector settings period at the same time, and
After being spaced the specified time, periodic scan is carried out successively to all sectors for generating bad track.
It should be noted that being only to determine sector after repairing successfully whether again by read scannings in the embodiment of the present invention
The secondary one way in which for generating bad track can also use other manner, the embodiment of the present invention not to limit.
It is of course also possible to including to the slitting where the sector of generation bad track or the sector including currently generating bad track
The region that multiple contiguous sectors are constituted is scanned, and the embodiment of the present invention does not limit the specific range of scanning.
The embodiment of the present invention by periodically actively to generate bad track and repair successful sector carry out read scannings come
It determines whether the sector generates bad track again, can find bad track in time, avoid hard disk in the prior art and need to wait for upper layer
Host service could carry out itself detection when reading the bad track, there are problems that delay so as to cause reporting fault.
If 303, the number of sector generation bad track reaches frequency threshold value, device carries out data to the data block where sector
Reconstruct.
When generating bad track due to a certain sector of hard disk, near there may be potential bad tracks for contiguous sector.If is produced from sector
The number of raw bad track reaches frequency threshold value, illustrate current sector generate again bad track possibility it is big, the reliability of current sector
Difference, the possibility that the sector adjacent with current sector is iteratively produced bad track is big, thus can by the data block where current sector,
I.e. nearby continuous multiple sectors carry out data reconstruction for current sector, avoid the data potential bad track in the block that data is caused to lose
It loses.Illustratively, when the frequency threshold value is 2, that is, it is bad to determine that current sector generates again after first time bad track reparation success
When road, then data reconstruction can be carried out to the data block where sector.Certainly, the frequency threshold value in this step can be 3 or its
It is worth, and can specifically be set according to actual conditions, the embodiment of the present invention does not limit.
Wherein, carrying out data reconstruction to the data block where sector may include:Extremely by the data block migration where bad track
The clear area of this hard disk or the clear area of other hard disks in addition to this hard disk, and data block in isolation hard disk.
It here can be by the clear area in this hard disk or the clear area of other hard disks in addition to this hard disk to production
Data block where the sector of raw bad track carries out data reconstruction, you can with by the sky of the data block migration where bad track to this hard disk
Not busy region or the clear area of other hard disks in addition to this hard disk.
Can refer to cancelling upper layer host business and the data block specifically, the data block in hard disk is isolated
Mapping relations, upper layer host business will not be written and read operation to the data block again, i.e., the data block is no longer used.In addition,
Carrying out data reconstruction to the data block where sector can also include, according to the migration position of data block where bad track, structure again
Redundancy check data is built, to constitute redundancy relationship with the data in other hard disks.
The embodiment of the present invention carries out data reconstruction by the data block where the sector to generating bad track again, can be timely
Restore the data in bad track, avoids in the prior art since present hard discs reporting fault has delay, if before reporting fault
The other hard disks for storing associated redundant data in current bad track or the potential bad track of data block also break down, then in this bad track of hard disk
Data the problem of can not restoring, you can, cannot be in time to hard to solve in the prior art since hard disk reporting fault has delay
Hard disc data is lost caused by disk failure is handled so that the problem of storage system poor reliability.
It should be noted that if the number that sector generates bad track is not up to frequency threshold value, then continue to repair, if repairing
Whether Scanning Detction that is successful then waiting for next period is generated with to determine current sector in Scanning Detction next time bad again
Road, and determine whether the number for generating bad track reaches frequency threshold value;BST labels are carried out if repairing failure.
304, device determines whether the quantity of the data block of present hard discs isolation is more than default isolation quantity, if more than then
The whole disk data of migration hard disk are set to failure to the clear area of other hard disks, and by hard disk.
In this step, however, it is determined that the quantity of the data block of present hard discs isolation is more than default isolation quantity (such as can be with
3), then show in present hard discs have multiple and different positions data sector in the block repairs successfully after another generation it is bad
Road, thus the hard disk generate again bad track possibility it is big, hard disk failure possibility it is big, the reliability of hard disk is low, so as to
To predict that present hard discs will fail.The whole disk data of hard disk before hard disk failure, can be thus migrated in advance to other hard
Hard disk is then actively set to failure, to notify user's removable disk, so as to will currently will in advance by the clear area of disk in advance
In Data Migration to the hard disk areas of safety in the hard disk of failure, avoid in the prior art due to present hard discs reporting fault
There is delay so that after hard disk failure, report other hard disks of associated redundant data in storage hard disk before hard disk failure
It breaks down, then the problem of data in this hard disk can not be restored.
Illustratively, hard disk is set to failure in advance in the embodiment of the present invention, it can be by by having in the disk state

The embodiment of the present invention will be described the processing method of hard disk failure by taking RAID-5 shown in Fig. 1 as an example, ginseng
See Fig. 4, may include following key step:
401, device receives the fault message that hard disk reports, and fault message includes the address information for the sector for generating bad track,
And record the address information of sector.
402, after sector is repaired successfully, device is scanned sector according to address property information cycle, determines sector
Whether after repairing successfully bad track is generated again.
Wherein, the detailed process of step 401~402 may refer to step 301~302.
If 403, the number of sector generation bad track reaches frequency threshold value, device continues to repair to sector.
In this step, if the number that sector generates bad track reaches frequency threshold value, in the hot standby region of present hard discs,
Continue to repair the slitting where current sector or current sector, specific repair process may refer to step 301.It is exemplary
, when the frequency threshold value is 2, that is, determine that current sector generates bad track again after first time bad track reparation success, that is,
It says in current sector after second generates bad track, continues to repair the sector.Certain frequency threshold value can also be it
Its numerical value, the embodiment of the present invention do not limit.
It should be noted that if the number that sector generates bad track is not up to frequency threshold value, then continue to repair, if repairing
Whether Scanning Detction that is successful then waiting for next period is generated with to determine current sector in Scanning Detction next time bad again
Road, and determine whether the number for generating bad track reaches frequency threshold value;BST labels are carried out if repairing failure.
If 404, device continues to repair successfully to sector, sector is verified.
If continuing to repair successfully to current sector in step 403, can school be carried out to the sector immediately in step 404
It tests.For example, can carrying out Verify verifications according to certain checking algorithm such as exclusive or algorithm to the sector, being continued with detecting
Whether the sector after repairing successfully is readable, i.e. detection continues whether the sector after repairing successfully can generate bad track again.It is exemplary
, the associated redundant data stored in other hard disks in same band in data and array in the sector can be read, and
XOR operation is carried out, if exclusive or result is 0, illustrates that the sector after continuing to repair successfully is readable, does not generate bad track again, then school
Success is tested, the Scanning Detction in next period is continued waiting for;Otherwise, illustrate that the sector after continuing to repair successfully is unreadable, it is current to fan
Area generates bad track again, i.e. current sector is failed immediately after continuing to repair successfully, verification failure.
It should be noted that if repairing failure is continued to sector, it may be considered that the sector unrepairable, thus can be right
It carries out BST labels.
If 405, device verification failure, the number that failure is verified in the present hard discs unit interval is carried out with predetermined threshold value
Compare, then enters step 406 or step 407.
406, when number is less than or equal to predetermined threshold value, device carries out data reconstruction to the data block where sector.
If verifying failure in step 404, show that current sector is failed or current sector immediately after continuing to repair successfully
There is only writeable unreadable situation, at this time it is considered that current sector unrepairable.Again since current sector may nearby deposit
In potential bad track, current sector unrepairable, then nearby sector generates bad track and the possibility of unrepairable is big for current sector, this
When the number that failure is verified in the present hard discs unit interval is compared with predetermined threshold value, if it is less than or equal to default threshold
Value, although illustrate present hard discs occur the sector unrepairable of bad track possibility it is big, which still passes through data weight
Data block where sector of the structure to generating bad track migrates, and the data block is isolated, thus can be to where current sector
Data block carry out data reconstruction, so as to restore in time in current sector and data block, there are in the sector of potential bad track
Data avoid in the prior art since present hard discs reporting fault has delay, if storing current bad track before reporting fault
Or other hard disks of associated redundant data also break down in the potential bad track of data block, then the data in this bad track of hard disk can not be extensive
Multiple problem, you can with solve in the prior art since hard disk reporting fault has delay, cannot in time to hard disk failure at
Hard disc data is lost caused by reason so that the problem of storage system poor reliability.
If 407, the number of verification failure is more than predetermined threshold value in the hard disk unit interval, device migrates the whole disk number of hard disk
According to the clear area of extremely other hard disks, and hard disk is set to failure.
If it is determined that the number of verification failure is more than predetermined threshold value (such as 3 times per hour) in the hard disk unit interval, then it can be with
Show in present hard discs there are multiple sectors for occurring bad track repeatedly, and sector unrepairable, thus the sector in present hard discs
Bad track is generated again and the possibility of unrepairable is big, and the possibility of hard disk failure is big, and the reliability of hard disk is low.It thus can be
Before hard disk failure, the whole disk data of hard disk are migrated in advance to the clear area of other hard disks, are then actively set to hard disk in advance
Failure, to notify user's removable disk, so as in advance by the hard disk of the Data Migration in the hard disk that will currently fail to safety
In region, avoid in the prior art after the failure of this hard disk, before hard disk reporting fault, relevant redundancy in storage hard disk
When other hard disks of data also break down, the problem of data in this hard disk can not be restored.
It is similar with step 304, hard disk is set to failure in advance in the embodiment of the present invention, it can also be by by the disk state
In effective status be set to failure state, and be reported to user.Wherein, the state of hard disk may include:To characterize hard disk energy
The effective status enough worked normally, and the failure state for showing hard disk cisco unity malfunction.And migrate the whole disk of hard disk
When other hard disks in data to the clear area of other hard disks, it can be migrated to the clear area of some hard disk,
It can migrate to the clear area of multiple hard disks, the embodiment of the present invention does not limit.
The embodiment of the present invention provides a kind of processing method of hard disk failure, by periodically to generate bad track and repair at
The sector of work(is scanned, and determines whether the sector generates bad track again, can be found bad track in time, be avoided in the prior art
Hard disk needs that itself detection could be carried out when upper layer host business being waited for read the bad track, exists so as to cause reporting fault and postpones
The problem of;It is then verified by reaching frequency threshold value to the number for generating bad track and continuing to repair successful sector, and right
Data block where verifying the sector of failure carries out data reconstruction, can restore that there are potential in current sector and data block in time
Data in the sector of bad track;In turn, when verifying the number of failure within the present hard discs unit interval more than predetermined threshold value, pass through
The whole disk data of migration hard disk are set to failure to the clear area of other hard disks, and by hard disk, to notify user's removable disk, Ke Yiti
