Embodiment
It is specifically real below in conjunction with the application to make the purpose, technical scheme and advantage of the application clearer
Apply example and technical scheme is clearly and completely described corresponding accompanying drawing.Obviously, it is described
Embodiment is only some embodiments of the present application, rather than whole embodiments.Based on the implementation in the application
Example, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belong to the scope of the application protection.
In the embodiment of the present application, source storage system can use different files to store from target storage system
Mode, such as, source storage system can use NAS modes, and target storage system can use OS modes,
Etc.；Source storage system can also use identical document storage mode with target storage system.Following reality
Apply example and be mainly based upon what the previous case illustrated.
The purpose migrated from source storage system to target storage system can be：So that system is stored by source before migration
The business that system provides, is changed into by target storage system after migration to provide.Seen on surface, the migration
The migration of file in the storage system of source can be referred to, substantially, the migration can be with reference and the file migrated
Part or all of business migration.For example before migration, user uploads lower publish papers for source storage system
Part, after migration, user can no longer upload for source storage system and download file, but be deposited for target
Storage system, which uploads, downloads file.
Moved for the file between the source storage system using different document storage modes and target storage system
Move, can include：The file type of this document in the storage system of source, to not supporting this document originally
The target storage system of type is transformed so that target storage system can support this document class after transformation
Type, and then again migrate this document in the storage system of source to target storage system.
Moved for the file between the source storage system using same file storage mode and target storage system
Move, can include：Directly by migrating to target storage system in the storage system of source, without transforming target
Storage system.
The core concept of the scheme of the application is：The related process of business migration can be divided into multiple ranks
Section, to realize migration steadily, in some stages wherein, source storage system and target storage system can be with
Parallel operation, the stability of target storage system before and after business migration can be speculated according to parallel running situation,
To decide whether to carry out business migration.The scheme of the application advantageously reduces the risk of business migration.
The scheme of the application is illustrated below.
Fig. 1 is a kind of process for business migration method that the embodiment of the present application provides.The executive agent of the process
It can be the equipment where the storage system of source, and/or the equipment where target storage system, and/or deposited with source
Storage system other equipment related to target storage system etc..These equipment can be specifically：Personal computer,
Big-and-middle-sized computer, computer cluster, mobile phone, tablet personal computer, intelligent watch, vehicle-mounted mobile platform etc..With
On the specific species of equipment enumerated be intended only as example, do not form the restriction to the application.
Process in Fig. 1 may comprise steps of：
S101：After by the file migration of source storage system to target storage system, in the text for being migrated
When part creates the first task of source storage system, the second task of target storage system is created, described second
Business corresponds to the first task.
In the embodiment of the present application, the file of source storage system can be moved to target storage system in batches
Move, integrally can also migrate the file of source storage system to target storage system.It is it is, in general, that previous
The advantages of kind of mode is：The simply a part of file migrated every time, the processing load of system is relatively small, right
System entire effect and risk are relatively small；The advantages of latter approach is：Text can comparatively quickly be completed
Part migrates and business migration.
In the embodiment of the present application, for file type corresponding to the various files in the storage system of source, in order to
Support these file types, it may be necessary to store according to the file that source storage system and target storage system use
The difference of mode, the correlative code of target storage system and the other systems on periphery is transformed so that
Improved code is adapted to the document storage mode of target storage system use.For example these codes can be with
It is related code of interface, file type, service logic etc..
Before above-mentioned code transformation is carried out, for source storage system and target storage system, can only it run
Source storage system with for outside offer business, and does not temporarily enable target storage system.That is, can be only
Task is created by source storage system and performs task, the task can be performed by document storage system
Task.
In the embodiment of the present application, after above-mentioned code transformation is proceeded by, for the file having moved,
Can be by way of source storage system and target storage system is run parallel, detection is in step s 102
Before and after the file migration of migration, the running situation of target storage system, to determine whether target storage system is steady
It is fixed.
In the embodiment of the present application, in order to prevent after file migration, target storage system is unstable and then shadow
The business of sound, after migrated file, it temporarily can still provide actual business by source storage system, and target
Storage system can then use the form of simulation, and simulation provides the business, that is, in second task that performs
When, substantive influence can not be produced to outside, advantage of this is that：Can not only it prevent target from storing
System shakiness Timing business, be also possible to prevent source storage system and target storage system repeat to provide it is identical
Business, so as to which the idempotence of business can not be ensured.
Specifically, the second task can not include target storage system and be operated with outside practical business, or
Target storage system is only included to operate with a part of practical business outside target storage system.So as to reality
When performing the second task now, target storage system can not be to the outside influence for producing essence.First task
Source storage system can be included to operate with outside practical business, first task is being performed so as to realize
When, source storage system can be to the outside influence for producing essence., can be by first task for the ease of description
Referred to as：Effective task；And the second task can be referred to as：Nonproductive task.
It should be noted that above-mentioned outside can refer to outside target storage system or outside target storage system
The overall outside in both portion or source storage system and target storage system.
S102：Perform the first task and second task.
In the embodiment of the present application, first task, the second task can perform simultaneously, can also be according to certain
Sequencing perform.
S103：Compare the first task implementing result and second task action result.
In the embodiment of the present application, the second task will not can be with to the outside influence for producing essence, but still
The influence of essence is produced to target storage system, such as, it can be deposited by performing the second task for target
Storage system generation file (being specifically as follows export etc.) and resolution file (be specifically as follows and import file)
Deng.
For the ease of description, can be referred to as with step S101~S102 this stage：Source storage system and target
Storage system is run parallel, and source storage system is as the leading stage.In this stage, can simultaneously base
In source storage system and target storage system generation file and resolution file etc., further, for outside
Speech, outside can read file and upper transmitting file etc. from source storage system, and can not stored from target temporarily
System reads file and upper transmitting file, because, target storage system still potentially unstable.
S104：After it is determined that comparison result is consistent, the business migration that source storage system provides to target is stored
System.
In the embodiment of the present application, it has been mentioned hereinbefore that migration can be speculated according to parallel running situation
The stability of front and rear target storage system, step S103 may act as a kind of specific implementation of the supposition
Mode.Generally speaking, for effective task and nonproductive task, if file corresponding to them successfully moves
Move, and source target storage system and target storage system normal table run, then compare their task
During implementing result, comparison result is consistent, conversely, comparison result is inconsistent.
In order to make it easy to understand, described " comparison result is consistent " is explained.For step S103, if
By comparing, file (such as generation file) and the second task that first task implementing result is related to are determined
The file content that implementing result is related to is identical, then can be determined that comparison result is consistent, conversely, can sentence
It is inconsistent to determine comparison result.If migration there is a problem or source storage system or target storage system it is unstable
When, the comparison result may be caused inconsistent.It is in actual applications, described that identical can to refer to file complete
It is equal, it can also refer to that file is not essentially equal, but the substantive content of file is mutually equal.For file,
In addition to substantive content, can there are some to can be used for carrying out substantive content in annotated add
Hold.
In the embodiment of the present application, after it is determined that comparison result is consistent, it is believed that the text of storage system in source
After part type migrates to target storage system, target storage system can be run with normal table, can be substituted
Source storage system provides business, then can by business migration that source storage system provides to target storage system,
So as to complete the business migration process.Afterwards, originally from source storage system obtain business user or
System, business can be obtained from target storage system.
In the embodiment of the present application, for step S101, if simply having migrated source storage to target storage system
The partial document of system and it is not all.Then accordingly for step S104, after it is determined that comparison result is consistent,
Business migration only source storage system being provided, corresponding to the file having moved stores to target is
System, and still being provided corresponding to the business of file not yet migrated by source storage system, and do not migrate still to
Target storage system.Or for step S104, can also temporarily not after it is determined that comparison result is consistent
Business migration is carried out, but after all files of source storage system are had moved, then carry out business migration.
It should be noted that the executive agent of each step in Fig. 1 may each be same equipment, or, should
Method can also be by distinct device as executive agent.Such as step S101 and step S102 execution master
Body can be equipment 1, and step 103 and step S104 executive agent can be equipment 2；Again for example, step
Rapid S101 executive agent can be equipment 1, and step S102~S104 executive agent can be equipment 2；
Etc..
, can be by respectively in source storage system and target for the file of migration by the method in Fig. 1
The mode for being related to this document of the task is performed in storage system so that source storage system and target storage system are simultaneously
Row operation, and can be decided whether to carry out business migration according to parallel running situation, therefore, compared to existing
Technology, the scheme of the application can reduce the risk of business migration, therefore, can partly or entirely solve
The problems of the prior art.
Based on the above method, the embodiment of the present application additionally provides some specific embodiments of the above method, with
And expansion scheme, it is illustrated below.
In the embodiment of the present application, before target storage system stability is not yet ensured, target storage system life
Into file be probably unreliability, can be with temporary interruption in order to reduce influence and the risk to related service
From target storage system to the file transmission channel of outside, to cause during the blocking, target storage system
File in system can not flow to outside, so as to will not also be impacted to related service.
Outside only can read file from the storage system of source, without reading file from target storage system.
Based on such consideration, for step S102, before performing the first task and second task,
It can also carry out：The file transmission channel outside from source storage system to source storage system is set to stay open shape
State, and the file transmission channel outside from target storage system to target storage system is remained turned-off shape
State.The concrete mode that the application opens or closes to control file transmission channel does not limit, usually,
Software switch or hardware switch can be used to be controlled.
In the embodiment of the present application, if by step S103, after determining that comparison result is consistent, it is believed that mesh
It is more stable to mark storage system, can be by business migration that source storage system provides to target storage system.
In practical application, the storage system situation different from the document storage mode that target storage system uses in source
Under, in order to realize file migration and business migration, it may be necessary to the file used according to target storage system
Storage mode, file access transformation is carried out to target storage system periphery, after causing transformation, outside can be with
The normally file in access target storage system.In the stage of file access transformation, can further examine
Survey the stability of target storage system, and reliability during file in access target storage system.
Specifically, file access transform during, can using target storage system as dominate, and incite somebody to action
Source storage system is run as auxiliary, for the ease of description, can be referred to as this stage parallel
" this stage ", this stage is that source storage system is run parallel with target storage system, and target storage system
As the leading stage (step S101~S102 is source storage system as the leading stage), in source
The first task and the second task that storage system creates as the leading stage, first task can deposit comprising source
Storage system operates with the practical business outside the storage system of source, and the second task can not include target storage system
Operated with the practical business outside target storage system.And in this stage, can be with source storage system as leading
The stage led is on the contrary, be illustrated below.
, can be with before the business migration that source storage system provides to target storage system for step S104
Perform following steps：
When for three task of the document creation source storage system migrated, target storage system is created
4th task, the 4th task correspond to the 3rd task；
Perform the 3rd task and the 4th task；
The 3rd task action result and the 4th task action result are compared, and determines comparison result
Unanimously.
Wherein, the 3rd task can not include source storage system and be grasped with the practical business outside the storage system of source
Make, or only include a part and operated with the practical business outside the storage system of source, held so as to realize
During the row task, source storage system can not be to the outside influence for producing essence；4th task can include mesh
Storage system is marked to operate with the practical business outside target storage system.
It can be seen that this stage is similar as the leading stage with source storage system, difference is：
This stage, be the task (the 3rd task) using source storage system as nonproductive task, and by target store be
The task (the 4th task) of system is used as effective task.In this stage, periphery can be according to its own system text
The time of part access transformation chooses the file in reading source storage system or target storage system.
Further, before this stage, execution the 3rd task and the 4th task, can also hold
OK：The file transmission channel outside from source storage system to source storage system is remained off, and is made
File transmission channel outside from target storage system to target storage system remains on.So as to mesh
File in mark storage system can flow to outside.
In the embodiment of the present application, perform first task and during the second task, or perform the 3rd task with
And during four tasks, it is contemplated that systematic function influences, can not simultaneously perform perform the 3rd task and
4th task, and the 3rd task and the 4th task are asynchronously performed, but can be held with staggering time
OK, so as to advantageously reducing system instantaneous pressure.
For example, for step S102, the first task and second task are performed, can specifically be wrapped
Include：The first task is performed, and after scheduled duration, performs second task.Certainly,
In actual applications, it is also possible to first carry out second.
In another example performing the 3rd task and the 4th task, can specifically include：Described in execution
4th task, and after scheduled duration, perform the 3rd task.
In the embodiment of the present application, in source storage system as leading stage or this stage, nonproductive task phase
Than in effective task corresponding to it, practical business operation can be skipped, nonproductive task typically can be adjusted only record
With parameter etc., and by parameter read-in destination file, compared for follow-up.
In actual applications, for target storage system, in addition to paying close attention to it and whether stablizing, typically can also
Its performance is paid close attention to, if performance can not meet predetermined demand, by the business migration that source storage system provides to mesh
After marking storage system, related service may be produced and had a strong impact on.Based on such consideration, deposited for source
Storage system, can also be to mesh in addition to comparing task action result as leading stage and this stage
The performance of mark storage system is also detected.
Specifically, be can also carry out in source storage system as leading stage and/or this stage：Determine mesh
Whether performance of the mark storage system when performing second task and/or four tasks meets predetermined need
Ask；If so, then can subsequently carry out business migration, otherwise, business migration can wouldn't be subsequently carried out, and
It is that target storage system is handled again for the performance issue found, after solving performance issue, then enters
Row business migration, it is thus possible to reduce business migration risk.
In the embodiment of the present application, ratio is determined as leading stage and/or this stage by source storage system
After and performance consistent to result has no problem, then business migration can be carried out.Specifically, mesh can only be created
The task of storage system is marked, and no longer creates the task of source storage system, is deposited by target storage system instead of source
Storage system provides the business such as file reading, File Upload and Download to outside.
By explanation above, in the embodiment of the present application, whole business migration process can be divided into
Multiple stages, to realize migration steadily.Based on such premise, in order to further improve the side of the application
The beneficial effect of case, it can be migrated in batches according to file type dimension in each stage, such as, can be with
By file all in the storage system of source, migrated in batches according to file type, when institute in the storage system of source
After some file types are in the stage corresponding to step S101~S103, downward single order in batches is further continued for
Section (can be this above-mentioned stage) promotes, and business migration is correspondingly conducted batch-wise and (or also may be used
Business migration is being carried out after to wait all files to migrate).Advantage of this is that：This can be caused
The scope that secondary migration influences is limited in several files of migration as far as possible, reduces overall complexity.
Based on the above-mentioned thinking migrated in batches, one kind that the embodiment of the present application provides process in Fig. 1 is specific
Implementation process.The specific implementation process can include：
The file type of file in the storage system of source, performed successively for every kind of file type：
After by the file migration of this document type to target storage system, for this document type
Document creation source storage system first task when, create the second task of target storage system,
Second task corresponds to the first task；Perform the first task and described second
Business；Compare the first task implementing result and second task action result；
After it is determined that comparison result corresponding to every kind of file type is consistent, business that source storage system is provided
Migrate to target storage system.
It should be noted that it is a kind of example to carry out migration in batches according to file type dimension, actually should
, can also be according to other dimensions (such as time dimension, business dimension etc.) in, and can also tie
Multiple dimensions are closed to be migrated in batches.
The business migration method provided above for the embodiment of the present application is illustrated, in order to make it easy to understand,
The embodiment of the present application is additionally provided under a kind of practical application scene, the realization to the moving method.
Under the practical application scene, the document storage mode that above-mentioned source storage system uses can be NAS
Mode, the document storage mode that above-mentioned target storage system uses can be OS modes, above-mentioned outside
Another predetermined file storage system can be referred to.
It should be noted that the application is to source storage system and target storage system in actual applications specific
Name title does not limit.For the ease of description, it is assumed that under the practical application scene, target storage system
Entitled network attached storage (Network Attached Storage, NAS) file system of system, below
Referred to as：NAS；Target storage system it is entitled：Object storage service (Object Storage Service,
OSS) file system, hereinafter referred to as OSS.Above-mentioned first task, the 3rd task can be NAS
Task, the second above-mentioned task, the 4th task can be OSS tasks.
In such a scenario, the transition process from NAS to OSS can be divided into 4 stages, migrated
When migration can be conducted batch-wise according to file type dimension.4 stages of division are referred to as NAS ranks
Section, NAS_OSS stages, OSS_NAS stages, OSS stages, as shown in Figure 2.It is directed to separately below
This 4 stages are described in detail.
The NAS stages：It can belong to the stage before code does not carry out OSS transformations.At this stage, may be used
Only to create NAS task, the task without creating OSS.
The NAS_OSS stages：The stage can think the stage corresponding to above-mentioned step S101~S103.It is right
, can be simultaneously based on NAS and OSS generation file and resolution file etc. in the file of stage migration.NAS
Task be effective task, OSS task is nonproductive task.Periphery is defined by NAS files, and now
Periphery can read file and upload according to predetermined policy still to be transformed without file access from NAS
File.In actual applications, NAS or OSS can be to outside offer business by periphery.
Specifically, in the task of establishment, two tasks can be created simultaneously for identical TaskWorker,
One task is to handle the task of NAS files, and another task is to handle the task of OSS files.Enter one
Step ground, will can stagger for the triggered time for triggering NAS task and OSS tasks carrying.Such as
NAS task can be triggered in current time, and OSS task can be in current time toward pusher
4 hours, in addition, span day during in order to prevent the execution of task, 19:00 later OSS task can
It is not to predetermined, it is necessary to explanation, to be within 4 hours the example of above-mentioned scheduled duration not toward pusher
The restriction of duration.
At this stage, in order to ensure operational idempotence, therefore, to assure that all business operation (for example adjust
With interface, send message etc.) only it must be performed by effective task (for NAS task), and aid in appointing
Business needs to skip practical business operation (that is, not comprising operated with the practical business of outside).Nonproductive task
Can only record call parameters etc., and by parameter read-in destination file, compared for follow-up.
At this stage, to close circular document and exchange upload OSS files opening to predetermined file storage system
Close (that is, above-mentioned remains turned-off the file transmission channel outside from source storage system to source storage system
State), to ensure that predetermined file storage system only takes the export of effective task generation.
It is possible to further which the NAS files in the stage are compared with corresponding OSS files, if than
It is identical to determination file content, and determine that OSS file process is stable, the time is subjected to model in business
Enclose, then can enter next stage.In actual applications, typically system can be superintended and directed after or is superintended and directed with after and be
System has the other systems of similar functions, performs the operation that file compares.
The OSS_NAS stages：At this stage, file can be generated by OSS to be defined, and notifies peripheral progress
OSS file accesss are transformed.
The stage still can generate file based on NAS and OSS simultaneously.It is with difference on last stage,
OSS task is effective task, and NAS task is nonproductive task, correspondingly, according to triggered as normal
Time, can by the triggered time of NAS task toward pusher, what periphery can transform according to its own system
Time selects to read OSS files or NAS files.
At this stage, in order to ensure operational idempotence, therefore, to assure that all business operation (for example adjust
With interface, send message etc.) only it must be performed by effective task (for OSS task), and aid in appointing
Business needs to skip practical business operation.Nonproductive task can only record call parameters etc., and by parameter read-in knot
Fruit file, compared for follow-up.
At this stage, to open circular document and exchange upload OSS files opening to predetermined file storage system
Close, and to close circular document and exchange the switch for uploading NAS files to predetermined file storage system, with
Ensure that predetermined file storage system only takes the export of effective task generation.
The OSS stages：
