As described in the background, the test tools used in the prior art, as shown in FIG. 1, all need to pass through the following modules: the kernel receives and sends the package, the file system processing and the upper software processing. As shown in fig. 2, the present application performs transceiving of a data packet and processes an NFS protocol in a user mode, and does not pass through a kernel and a file system.
Example one
Specifically, as shown in fig. 3, the process of performing the NFS service test in the embodiment of the present application includes:
s100, deploying an NFS-Ganesha environment, constructing a request message of a tested function, and deploying a rapid data packet processing framework in a test program.
Specifically, in the test program in the present Application, a program developed by a developer includes multiple API (Application Programming Interface) interfaces, and is used to invoke a fast packet processing framework to perform a user mode program for receiving and sending a message. Determining a tested function request to be constructed, such as a write request, a read request, a directory acquisition request and the like, according to a function to be tested of a test client; and then, the test program constructs a tested function request parameter according to the function simulation required to be tested according to the NFS protocol standard, and a tested function request message is generated. When the tested function request message is constructed, a tested function request message can be constructed independently, and a tested function request message set can be constructed to simulate real storage IO.
In this embodiment, the NFS-Ganesha (user mode network file system) user mode network file system source code environment may be a CentOS 7.2 version environment, or may be another version of NFS-Ganesha obtained from a GitHub open source community. The NFS-Ganesha is a File server supporting NFS protocol (NFSv3/NFSv4, NFSv4.1) in user mode, and provides a FUSE (File system in user space File system) compatible interface FSAL (File system abstraction Layer) for Unix and Unix-like operating systems. Thus, the user can access the own storage device through the NFS client. The NFS-Ganesha service allows a user to access data in a user mode through the FSAL without frequent interaction with a kernel, and response time of data reading is greatly reduced.
Among them, the fast Data packet processing framework (DPDK) is used to accelerate packet Data processing, mainly responsible for accessing the underlying resources of the computer and encapsulating the details of the interface embodiment provided to the user. The DPDK is dedicated to high-performance processing of data packets in network application, and is particularly embodied in that a DPDK application program runs on a user mode and utilizes a self data plane library to receive and transmit the data packets, a kernel protocol is bypassed for processing the data packets, the data packets do not pass through a kernel and a file system, delay is reduced, and unnecessary system call is avoided.
And S200, sending a tested function request message to the NFS server according to the rapid data packet processing frame.
It should be noted that, at this time, the network card has already been taken over by the test program to implement the fast packet processing framework to directly send and receive the function request message, and the step of taking over the network card includes: issuing network card configuration, setting a network card receiving queue, setting a network card sending queue and starting the network card. The specific content of each step is the prior art in the field, and the detailed description of the present application is omitted here.
And S300, the NFS server receives the tested function request message and verifies the test function request message to be normal.
Specifically, the NFS server checks the legality and normalization of the format of the function request message to be tested according to the NFS protocol format standard, and if the format of the function request message to be tested conforms to the NFS protocol format standard, the NFS server executes the function to be tested; if the format of the tested function request message conforms to the standard of the NFS protocol format, that is, the tested function request message is not established legally and normatively, and the NFS server does not execute the tested function.
S400, after the tested function request message is detected to be normal, the NFS server executes the tested function and generates an execution result.
Specifically, the NFS server executes the tested function and returns an execution result to the local service process, and the local service process encapsulates the received execution result in the tested function request message; wherein the execution result at least comprises: packet size and execution status.
S500, the NFS server sends the tested function request message encapsulated with the execution result to the NFS client, and the NFS client receives the tested function request message and records the encapsulated execution result to complete the test.
And the NFS client calls the NFS protocol to analyze the received tested function request message and acquire an encapsulated execution result. The NFS client records the size of a data packet in an execution result, and the data packet is used for representing the performance of the function to be tested. Because the requirements of the tested functions on the size of the data packet are different under the normal operation condition, in the specific application, the requirements of the tested functions on the size of the data packet are compared with the size of the data packet in the execution result, and if the size of the data packet in the execution result can meet or approximately meet the requirements of the tested functions on the size of the data packet, the tested functions are proved to have high operation performance in the test environment.
The NFS client records the execution state in the execution result, and if the recorded return value of the execution state is OK, the tested function is proved to run normally in the test, and the tested function can be realized in the test environment; if the return value of the execution state is not recorded or the recorded return value of the execution state is not OK, the tested function is proved to be abnormal in operation in the test, and the tested function cannot be realized in the test environment.
The method for testing the NFS service, disclosed by the embodiment of the application, can realize the construction of the message in the user mode without a kernel and a file system, receive and send the message in the user mode, and test the function and performance of the NFS service by simulating the message receiving and sending process.
