The present embodiments relate to be repaired to specified file, wherein, specified file is to be carried using the embodiment of the present invention
The file that the Ile repair method of confession is repaired, the file type in the embodiment of the present invention to specified file is not limited, only
Wanting certain file in production system can be repaired using Ile repair method provided in an embodiment of the present invention, this document
It is considered as specified file.It is related to two file system, i.e. production system and standby system when being repaired to specified file.
Wherein, production system is used to provide file read-write service for terminal device, and standby system is stored with production system
Identical file.That is, when the specified file stored in production system is not damaged, production system can be carried for terminal device
For file read-write service；When partial data block is damaged in the specified file stored in production system, production system can be according to standby
The specified file stored in part system is repaired to the specified file that itself is stored, and after the completion of reparation, production system can continue
For terminal device provides file read-write service；When the file stored in production system cannot be repaired, user can be set by terminal
It is standby that standby system is switched to the file system for providing file read-write service.
Standby system and production system are stored with identical file, can be realized by following three kinds of modes：
First way：It is synchronous to replicate
The file that standby system is synchronously replicated with production system storage can be realized by the file writing process shown in Fig. 2.
In Fig. 2, it is assumed that terminal device will include this five data blocks of A, B, C, D and E to the file 1 write in production system, then eventually
End equipment in production system write file 1 when, it is necessary to be respectively written into five data blocks of A, B, C, D and E to production system.To write
As a example by entering data block A, terminal device writing data blocks A first in production system, then production system sent to standby system
The instruction of writing data blocks A, after standby system is successfully written data block A, standby system sends to production system and writes successfully
Instruction message, it is successful that production system sends write-in after confirming that standby system is successfully written into data block A, to terminal device
Indicate message.Data block B, C, D are identical with the ablation process of data block A with the ablation process of E, and here is omitted.Work as data
After block A, B, C, D and E complete ablation process, that is, complete the ablation process of file 1.
Additionally, when standby system is synchronously replicated with the file of production system storage, if terminal device will be to production system
The data block of middle storage is modified, it is also desirable to while the respective data blocks to being stored in standby system are modified.
The second way：Asynchronous replication
The file that standby system asynchronous replication has production system storage can be realized by the file writing process shown in Fig. 3.
In figure 3, need to configure synchronizing cycle between standby system and production system, when not arriving synchronizing cycle, for terminal device
To the data block that production system writes, production system only need to record the data block in the difference bitmap of itself storage, and nothing
The data block need to be write standby system；When arriving synchronizing cycle, production system writes the data block recorded in difference bitmap
Enter standby system.Such as, terminal device will include this five data blocks of A, B, C, D and E to the file 1 write in production system,
Assuming that at the end of a upper synchronizing cycle, A, B, C these three data blocks were had been written into production system and standby system.
When this synchronizing cycle does not arrive, terminal device is recorded to production system writing data blocks D, production system in difference bitmap
Data block D, then to production system writing data blocks E, production system records data block E to terminal device in difference bitmap；
When arriving this synchronizing cycle, data block D and data block E the write-in standby system that production system will be recorded in difference bitmap.
Additionally, when the file that standby system asynchronous replication has production system to store, if terminal device will be to production system
The data block of middle storage is modified, and production system need to be recorded in difference bitmap when not arriving synchronizing cycle and repaiied
The data block for changing.When arriving synchronizing cycle, the data block that production system will be recorded in difference bitmap writes standby system.
Especially, when standby system is synchronously replicated or asynchronous replication has the file that production system is stored, standby system is again
It is properly termed as disaster recovery and backup systems.Production system can not only be carried out according to the file stored in disaster recovery and backup systems to the file for itself storing
Repair, and when production system is stopped because of unexpected (such as fire, earthquake), user can be by terminal device by the standby system of calamity
System switches to the file system for providing file read-write service, and it is literary that disaster recovery and backup systems can continue as terminal device offer instead of production system
Part read-write service.
The third mode：Backup
The file that standby system backup has production system storage can be realized by the file writing process shown in Fig. 4.With it is standby
The system asynchronous process for replicating the file in production system of part is similar to, and backup has the file stored in production system in standby system
Process standby system can be write by the data block that will periodically record in difference bitmap and realize.With asynchronous replication process
Unlike, for certain file, multiple copies may be backed up in standby system.Such as, terminal device will be to production
The file 1 write in system includes this five data blocks of A, B, C, D and E, it is assumed that at the end of a upper synchronizing cycle, production system
With A, B, C these three data blocks have been had been written into standby system, the copy 1 of file 1 is by data block A, B, C groups in standby system
Into.When not arriving this synchronizing cycle, to production system writing data blocks D, production system is in difference bitmap for terminal device
Data block D is recorded, then to production system writing data blocks E, production system records number to terminal device in difference bitmap
According to block E；When arriving this synchronizing cycle, production system backups to the data block D and data block E that are recorded in difference bitmap standby
In part system, the copy 2 of file 1 is made up of data block A, B, C, D, E in standby system.Wherein, copy 2 is the pair of latest edition
This.
Additionally, when standby system backup has the file that production system is stored, if terminal device will be in production system
Data block is modified, and production system need to be recorded in difference bitmap when not arriving synchronizing cycle and carry out the data of modification
Block.When arriving synchronizing cycle, the data block that production system will be recorded in difference bitmap writes standby system, forms another secondary
This.
In above-mentioned three kinds of modes, during using synchronous reproduction mode, standby system is complete with the file of storage in production system
It is complete consistent；During using asynchronous replication or backup mode, the file that standby system is periodically stored in synchronous production system, backup
The data block included in the file stored in system and production system is not necessarily completely the same.Deposited in standby system and production system
The not necessarily completely the same concrete meaning of the data block included in the file of storage is：The text stored in standby system and production system
Part is identical, but for identical file, when not arriving synchronizing cycle, production system may be to some of this document data block
It is modified, and the data block that will be changed is recorded in difference bitmap, but because the time that the modification occurs is synchronizing cycle
Before arrival, therefore data block in standby system in this document does not make corresponding modification.
In the prior art, it is necessary to be operated manually by user when being repaired to the file stored in production system.
When production system determines that some data blocks have been damaged in the file of itself storage, production system reports an error to terminal device, reads
Service disconnection；After the reporting an error of production system is received, user is manually switched to standby system to terminal device, and standby system will be bad
The corresponding data block of block returns to terminal device, and the data block is sent to production system by terminal device, and production system is available
The data block is repaired to the data block damaged in corresponding document.This file repair procedures need user's manual switching file
System, repair process can cause production system to stop as terminal device provides file read-write service, that is, cause the industry of file system
Business is interrupted.
In order to the file system traffic existed when solving and being repaired to the file in file system in the prior art is interrupted
Problem, the embodiment of the present invention provides a kind of Ile repair method.As shown in figure 5, the method comprises the following steps：
S501：The first read requests that production system receiving terminal apparatus send.
First read requests are used for the specified file for asking to read production system storage.
In the embodiment of the present invention, terminal device includes but is not limited to smart mobile phone, intelligent watch, panel computer, virtual existing
It is real (Virtual Reality, VR) equipment, augmented reality (Augmented Reality, AR) equipment, personal computer, hand-held
Formula computer, personal digital assistant.

S503：Production system sends the second read requests to standby system.
Wherein, standby system and production system are stored with identical file, and the second read requests are used to ask to read backup
At least one data block corresponding with least one bad block in the specified file of system storage.
Wherein, at least one data block is data block corresponding with least one bad block.Assuming that stored in production system
File 1 includes five data blocks of A, B, C, D, E, and data block C therein and data block D is two bad blocks, then in standby system
The file 1 of storage also includes five data blocks of A, B, C, D, E, is with one-to-one two data blocks of at least the above two bad blocks
It is the data block C and data block D that are stored in standby system.
S504：Standby system sends at least one data block to production system.
S505：Production system is repaired according at least one data block to the specified file that production system is stored.
In the embodiment of the present invention, standby system is stored with identical file with production system can be by above-mentioned three kinds of mode realities
It is existing, i.e., synchronous duplication, asynchronous replication and backup, here is omitted.
Alternatively, production system, can be by after reparation after execution S505 is repaired to the specified file that itself is stored
Specified file is sent to terminal device, so as to after the completion of specified file reparation, realize that production system provides reading for terminal device
Take the service of specified file.
Alternatively, production system, can also be in specified file except extremely before S504 at least one data blocks of reception are performed

At least one data block can be sent to terminal device, so that, production system can be real while being repaired to specified file
Now for terminal device provides file read-write service.
Standby system and production system are stored with identical file when being realized by above-mentioned three kinds of modes, using different realities
Existing mode, the specific implementation for repairing the specified file of production system storage can be different.
When standby system is synchronously replicated with the file of production system storage, in S505, production system is according at least one
Data block is repaired to the specified file that production system is stored, and can be realized in the following way：Production system receive to
After a few data block, at least one data block is write under the storage address of at least one bad block, you can complete to production
The repair process of the specified file of system storage.
The file of production system storage, thus standby system and storage in production system are synchronously replicated with due to standby system
File it is completely the same.When production system is repaired to the specified file that itself is stored, can directly at least one bad block
At least one data block that standby system sends is write under storage address.Using such scheme, synchronously it is replicated with standby system
During the file of production system storage, there is provided a kind of method of the specified file of reparation production system storage.

Write at least one data block, you can complete the repair process of the specified file to production system storage；
Second situation
Record is when having at least one bad block in dystopy of being on duty figure, production system stored according to itself at least one bad block
The modification mode modified, is accordingly changed at least one data block, and at least one bad block after the completion of modification
Storage address under write amended at least one data block.
When standby system asynchronous replication or backup have the specified file that production system is stored, because standby system is only same
Step period carries out the synchronous of data block when arriving with production system, therefore, need to store variant bitmap in production system, for remembering
Which data block is recorded to carry out not carrying out the corresponding data block changed in modification, standby system in production system.Additionally, raw
The modification mode of the data block recorded in variant bitmap can be also stored in product system, so that production system itself is deposited in reparation
During the specified file of storage, the modification mode according at least one bad block makes corresponding modification at least one data block.
It should be noted that when record has the partial data block at least one bad block in dystopy figure of being on duty, production system
After at least one data block is received, the modification mode of the partial data block that can be stored according to itself is entered to partial data block
Row modification, and at least one data block of partial data block will be changed as amended at least one data block, then will
Amended at least one data block writes on the storage address of at least one bad block, you can completion is specified to production system storage
The repair process of file.
Such as, four bad block A, B, C, D are included in the specified file of production system storage, then corresponding with four bad blocks
Four data blocks are that tetra- data blocks of A, B, C, D in the specified file of standby system storage, i.e. production system send the second reading
After taking request, tetra- data blocks of A, B, C, D can be sent to production system by standby system.If record has A and B two in difference bitmap
Individual data block, i.e. A and B carried out modification in production system, corresponding modification were not carried out in standby system, then production system
Unite after tetra- data blocks of A, B, C, D for receiving standby system transmission, can be according to the A and the modification mode pair of B for itself storing
Data block A and data block B in tetra- data blocks of A, B, C, D that standby system sends modify, and will change A's and B
Then amended four data blocks are write on four storages of bad block by four data blocks as amended four data blocks
Location.
