Each node shares data through a network, and in an actual application scene, each node and a client of the distributed file system can be interconnected through a gigabit network or a ten-gigabit network.
In the field of video application, a client acquires video data from each node through a network based on a data sharing protocol of a distributed file system. For the field of video monitoring, video monitoring data transmission between client streaming media software and nodes and between video management software and nodes is completed through a data sharing protocol of a distributed file system.

In specific implementation, the requirement information of the client includes information such as the number of camera paths supported by the client, the bandwidth of each path, and the sharing protocol used.
Wherein, the sharing protocol used will be different based on the different operating systems of the client. For example, the Network File System (Network File System) sharing protocol is mainly applied in the Linux environment, and the public Internet File System (Common Internet File System) sharing protocol is mainly applied in the windows environment. The user space file system (file in user space) sharing protocol is mainly applied in the Linux environment.
S11: according to a sharing protocol used by a client, a virtual machine client with an operating system corresponding to the sharing protocol is created in a node of the distributed file system.
In specific implementation, in a node of the distributed file system, a kernel-based open-source virtualization module may be used to construct a virtual machine client of an operating system corresponding to the sharing protocol. For example, a Kernel-based Virtual Machine (KVM module) is used to create a Virtual Machine client in a node.
According to the method, the virtual machine client is created in the node according to the sharing protocol used by the client, so that not only are hardware resources isolated in actual production, but also the influence of the streaming media service on the storage service is shielded, and the cost and the resource space are saved for enterprises.
S12: and selecting a corresponding code stream testing tool to perform simulation test of the client scene direct current storage according to the operating system of the virtual machine client.
The client operating systems are different, and a virtual machine client with a corresponding operating system is created in the node. For example, the client operating system may be a Windows operating system or a Linux operating system, and a virtual machine client having a corresponding operating system is created according to the operating system corresponding to the client, and an appropriate code stream test tool is selected.
For example, the Storcube code stream test tool can be selected to be adopted corresponding to the Windows operating system, and the Btest code stream test tool can be selected to be adopted corresponding to the Linux operating system.
In this step, referring to fig. 3, the simulation test specifically includes the following steps:
s120: compiling a test script and setting parameters according to the selected code stream test tool, and pushing the test script to a virtual machine client of the node;
s121: executing the test script in the virtual machine client;
s122: and after the test script is executed, obtaining test log information and recording a test result.
And after the test is finished, exporting the test log information and the test result, and ending the test.
According to the method for testing the direct current storage of the distributed file system, the simulation test of the direct current storage of the client scene is realized, the existing performance problem can be found as early as possible according to the test result obtained by the simulation test, the obtained test result provides reference for whether the client needs to test on site, the test period is shortened, and the test efficiency is improved.

In specific implementation, a kernel-based open-source virtualization module can be adopted to construct a virtual machine client of an operating system corresponding to the sharing protocol. For example, a Kernel-based Virtual Machine (KVM module) is used to create a Virtual Machine client in a node.
Virtual machine clients are created on a plurality of nodes of the distributed file system, so that a scene with a large number of client video paths can be simulated, for example, 48 paths are total, each node virtual machine client can be divided into 16 paths, and the problem that resources such as a single virtual machine client memory and a CPU (Central processing Unit) are excessively consumed can be avoided. S22: and selecting a corresponding code stream testing tool to perform simulation test of the client scene direct current storage according to the operating system of the virtual machine client.

s220: and compiling a test script and setting parameters according to the selected code stream test tool, and pushing the test script to the virtual machine client of each node.
For some kinds of code stream testing tools, for a node, a virtual machine client of the node itself can be selected as a host client or a non-host client, and for a node virtual machine client selected as the host client, the virtual machine client can be simultaneously selected as the non-host client. Specifically, the client is selected as the primary client or the non-primary client by setting parameters.
For example, the node itself may be selected to be the host client or the non-host client corresponding to the stortube code stream testing tool used by the Windows operating system. And for the Btest code stream testing tool used by the Linux operating system, the selection of the host client and the non-host client is not carried out.
S221: and judging whether the test scripts of the virtual machine clients in the nodes are synchronous or not.
If not, returning to the step S220, rewriting the test script and setting parameters.
If yes, go to step S222.
S222: and executing the test script.
S223: and after the test script is executed, obtaining test log information and recording a test result.
If the nodes are selected as the main client nodes or the non-main client nodes, the nodes serving as the main clients are responsible for acquiring the test log information and the test results from the non-main client nodes.
And after the test is finished, exporting the test log information and the test result, and ending the test.
