Step 101, client plug-in receive the NFS request that NFS clients send.
In the present embodiment, client call request sends function and sends NFS request to client plug-in,
Client plug-in sends function by customized treatment function replacement request, so that NFS request is intercepted and captured,
Client plug-in carries out turning for NFS request by the customized treatment function effective communication link of selection
Hair.
NFS request is cloned in step 102, client plug-in clone's NFS request, generation at least two.
In the present embodiment, because client needs to send NFS request to multiple NFS service nodes simultaneously,
Accordingly, it would be desirable to NFS request is cloned, the multiple NFS requests of generation.
Step 103, client plug-in are sent out at least two clone's NFS requests by communication link respectively
Give at least two NFS service nodes.
Wherein, at least two NFS service nodes have consistent NFS data.
In the present embodiment, before service is provided to client, for same main frame provides NFS services

The reliability of NFS.
Fig. 4 is the exchange method flow chart based on NFS that the embodiment of the present invention two is provided.In above-mentioned Fig. 3
On the basis of illustrated embodiment, in step, " client plug-in sends out at least two clone's NFS requests respectively
After giving at least two NFS service nodes ", as shown in figure 4, the method is further comprising the steps of：
Step 201, client plug-in are obtained by default call back function and return to error code.
Wherein, default call back function is used to obtain the operation conditions and hair of at least two NFS service nodes
Send clone the communications link condition of NFS request.
In the present embodiment, clone's NFS request is transmitted to after NFS service nodes, whenever NFS
Request is completed, and no matter NFS request succeeds or failure, can all return to default call back function, passes through
Call back function, client plug-in can obtain the performance of each NFS request, be returned such that it is able to basis
Return error code and judge whether service node or transmission link break down, if need the toggle path to carry out
The forwarding of NFS request.
Step 202, client plug-in judge to send the communication chain of clone's NFS request according to error code is returned
Whether break down on road；If so, i.e. client plug-in determines that the communication link of NFS request breaks down,
Step 203 is then performed, if it is not, i.e. client plug-in determines that the communication link of NFS request is normal, is then held
Row step 204.
In the present embodiment, judge whether communication link fails occur according to the type for returning to error code, if
The return error code is the error code of communication link fails type, then explanation sends the logical of clone's NFS request
Whether letter link breaks down.
Step 203, client plug-in are by other any chains between main frame and target NFS service nodes
Road sends clone's NFS request.
In the present embodiment, when certain communication link breaks down, client plug-in can be from other
Communication link arbitrarily selection one resends clone's NFS request.For example, main frame and one of those
Multiple communication links are deposited between NFS service nodes, when client plug-in sends NFS using main IP links
During request, main IP links break down, then other between main frame and the NFS service nodes are for IP
One link forwarding NFS request of any selection in link.
Alternatively, if all communication links between main frame and target NFS service nodes break down,
Then target NFS service nodes are labeled as malfunctioning node by client plug-in, and are alerted.
In the present embodiment, if client plug-in retried one by one main frame and target NFS service nodes it
Between all links send NFS request, but all send failure, then these links all break down, then
Target NFS service nodes are labeled as malfunctioning node by client plug-in, and are alerted, for example, passing through
Display interface sends prompt message to user, convenient timely to notify user's NFS service node failures
Failed services node is repaired.
Wherein, target NFS service nodes are the corresponding NFS service nodes of the communication link for breaking down.
Step 204, client plug-in are continuing with original communication link and send clone's NFS request.
The exchange method based on NFS that the present embodiment is provided, after transmission clone's NFS request, client
Plug-in unit is obtained by default call back function and returns to error code, judges to send clone according to error code is returned
Whether the communication link of NFS request breaks down, if event occurs in the communication link for sending clone's NFS request
Barrier, then send clone by other any links between client plug-in and target NFS service nodes
NFS request, so as to ensure the reliability of communication link between NFS service nodes and main frame.
Fig. 5 is the exchange method flow chart based on NFS that the embodiment of the present invention three is provided.The present embodiment with
NFS includes as a example by a NFS service nodes and the 2nd NFS service nodes, detailed description Fig. 3 or
The specific implementation of embodiment illustrated in fig. 4.On the basis of embodiment illustrated in fig. 3, in step " visitor
Be sent respectively at least two clone's NFS requests after at least two NFS service nodes by family end plug-in unit "
Afterwards, the method also includes：
Step 301, client plug-in receive the first request response of NFS service nodes transmission respectively
The the second request response sent with the 2nd NFS service nodes.
Wherein, the first request response includes being processed into work(message or processing failure message, the second request response
Including treatment success message or processing failure message.
In the present embodiment, NFS service nodes receive client plug-in transmission clone's NFS request after,
Request response can be returned to client plug-in, the request is responded for representing whether NFS request is processed successfully.
It should be noted that failed message can be disappearing for the first expression processing failure of NFS service nodes generation
Breath, or client plug-in are not received at the appointed time after it have sent NFS request
When the request that NFS service nodes are returned is responded, then it is assumed that send NFS request failure.
Step 302, client plug-in are processed the first request response and the second request response.
In the present embodiment, client plug-in will clone NFS request be transmitted to NFS service nodes it
Afterwards, it is necessary to after waiting the corresponding request response of all of clone's NFS request all to receive, could basis
All of respond request judges the completion result of NFS request, so as to return to treatment knot to upper strata client
Really.Because clone's NFS request is independently transmitted by each self-corresponding communication link, so existing several
Possible request response results combination is planted, client plug-in is needed according to these combinations to correspondingly upper strata
Client returns to result, particularly may be divided into following three kinds of situations：
The first situation：If the first request response and the second request response include treatment success message,
Client plug-in returns to treatment success response to NFS clients.
In the present embodiment, if the first request response and the second request response include treatment success message,
Link then between explanation main frame and two NFS service nodes is normal, also, two NFS service nodes
Also normal operation, can provide service for main frame.
Second situation：If the first request response and the second request response include processing failure message,
Client plug-in returns to processing failure and responds to NFS clients.
The third situation：If a request response in the first request response and the second request response includes place
Reason success message, and another request response includes processing failure message, then client plug-in is to NFS visitors
Family end returns to treatment success response.
In the present embodiment, if a request response in the first request response and the second request response includes
Treatment success message, and another request response includes processing failure message, for example, a NFS is serviced
The first request response that one communication link of node is returned includes processing success message, the 2nd NFS clothes
Include processing failure message in the second request response that all communication links of business node are returned, then illustrate
First NFS service node normal operations, therefore, client plug-in is to the success of NFS clients transmission processe
Response.
It should be noted that in second and the third situation, if NFS request processing failure, first
To judge that the reason for causing unsuccessfully is that communication link fails or NFS services occur according to error code is returned
It is abnormal, if the processing failure message that the reason for causing NFS request processing failure returns for NFS service nodes,
Other communication links need not then be retried；If the reason for causing NFS request processing failure is communication link
Failure, then client plug-in need to attempt one by one other all communications between main frame and NFS service nodes
Link, if other communication links break down, illustrates that the NFS service nodes are unreachable, it is impossible to
For main frame provides service.
Alternatively, the first request response includes first state value, and the second request response includes second
State value, then after step 302, to NFS clients return result before, can also include
Following steps：
Step 303, client plug-in generate virtual state value according to first state value and the second state value,
And preserve the corresponding relation between virtual state value and first state value and the second state value.
Step 304, client plug-in are returned to NFS clients includes the result of virtual state value.
In the present embodiment, result includes that virtual state value, treatment success response or processing failure are rung
Should.For v3 and former NFS protocol version, because being stateless agreement, it is not related to shape
State treatment, and v4 protocol versions introduce State concept, and one can be carried in the request that NFS clients send
A little status informations, NFS service ends can be verified after receiving status information, so as to judge an operation
Validity, status information generates by NFS service ends and safeguarded (such as FileHandle, StateID etc.),
The status information of different NFS service ends generations can be variant, so client plug-in is needed according to state
Information carries out specially treated to state.The status information can be the state value in the present embodiment, i.e., first
State value is the information of the validity for verification operation of the service end generation in a NFS service nodes
Value, the second state value is the service end generation in the 2nd NFS service nodes for the effective of verification operation
The value of information of property.
In addition, the state value that each NFS service nodes return to client plug-in is actual value, client is inserted
Part needs the real state value returned according to each NFS service nodes to generate virtual state value, then will be virtual
State value is sent to client also, client plug-in also needs to be virtual state value and real state value
Between corresponding relation safeguarded.Virtual state value can be deposited with Hash sheet forms, each Hash
List item includes the pointer for pointing to real state value pair.Fig. 6 is a kind of virtual state value and real state
The mapping table of value.As shown in fig. 6, depositing virtual state value and real state value in the form of Hash tables
Between corresponding relation, each virtual state value correspond to two real state values.
Alternatively, step 303 can also be performed before step 302, and step 303 can also be with step
301 perform simultaneously, are not any limitation as in the present invention.
The exchange method based on NFS that the present embodiment is provided, client plug-in receives a NFS respectively
The second request response that the first request response and the 2nd NFS service nodes that service node sends send, it is right
First request response and the second request response are processed, so as to differentiate communication link and NFS service sections
Whether point is broken down, and result is returned into NFS clients, in order to faulty link and event
Barrier node is timely safeguarded.If the first request response includes first state value, and second request
Response includes the second state value, then client plug-in is virtual according to first state value and the generation of the second state value
State value, and the corresponding relation between virtual state value and first state value and the second state value is preserved, visitor
