Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
For a better understanding of the present application, embodiments of the present application are explained in detail below with reference to the accompanying drawings.
Example one
Referring to fig. 1, fig. 1 is a schematic flowchart of a testing method for NFS sharing maximization provided in an embodiment of the present application. As shown in fig. 1, the testing method in this embodiment mainly includes the following steps:
s1: and according to a preset NFS sharing number M, creating M NFS shares in the NAS cluster of the storage end, wherein M is a natural number.
The method for testing the maximum NFS sharing mainly includes the steps of firstly obtaining an NFS sharing number M set by a user according to different storage products, then judging whether the storage products can successfully create M NFS shares, and successfully mounting the M NFS shares to a client. And judging whether the mounting is successful or not by checking the mounting result, and embodying the mounting result in the script, namely the script can run from the beginning to the end at one time without stopping in the middle, and judging that the NFS sharing maximization test is qualified. Therefore, in the embodiment, a preset value is set for the NFS sharing number, which is the reference standard for the NFS sharing maximization test, so that the result of the NFS sharing maximization test can be effectively and accurately judged, and the improvement of the test efficiency and the accuracy of the test result are facilitated.
In this embodiment, the number M is a natural number, and the specific numerical value is set according to the performance of different storage products.
Specifically, step S1 includes the following processes:
s11: a storage pool is created in a NAS cluster at a storage side.
A storage pool is a set of disks in which a DPM (Data Protection Manager) server stores copies, volume copies, and transfer logs, and is a virtual resource pool.
S12: m file systems are created in a storage pool.
The file system is created specifically at the storage nodes specified in the storage pool.
S13: and respectively creating one NFS share in each file system, and creating M NFS shares in total.
For all file systems created in a specified node, NFS sharing is performed on the file systems, that is: one NFS share is created in each file system, with M NFS shares created.
After the storage side creates the NFS share, step S2 is executed: and sequentially mounting M NFS shares at the client according to the obtained mounting instruction.
One NFS share may match multiple different clients, and one client may match multiple NFS shares, in this embodiment, one client matches multiple different NFS shares. That is, after creating the NFS shares, the NFS shares are sequentially added to the client. In this embodiment, the client is a Linux server.
S3: and determining the sharing number of the actually mounted NFS according to the number of the file systems which can be shared in the NAS cluster.
The number of file systems that can be added by the client, that is, the number of file systems that can be shared by the client, and at the same time, the number of NFS shares that the client actually mounts successfully. Therefore, the number of NFS shares actually mounted can be determined according to the number of file systems that can be shared in the NAS cluster.
S4: and judging whether the actually mounted NFS sharing number is consistent with the preset NFS sharing number.
S5: if so, judging that the NFS sharing maximization test is qualified;
s6: and if not, judging that the NFS sharing maximization test is unqualified.
Specifically, in the script execution process, if the script can run from the beginning to the end at one time without stopping in the middle, the actually mounted NFS sharing number and the preset NFS sharing number are generally consistent, and at this time, it is determined that the NFS sharing maximization test is qualified. Otherwise, if the script is stopped in the midway, it is indicated that a part of NFS sharing creation is unsuccessful, and at this time, the actually mounted NFS sharing number is usually smaller than the preset NFS sharing number, so that it is determined that the NFS sharing maximization test is unqualified.
Furthermore, the embodiment further includes creating a log file, and the log file is created to call the log, so that error information in the test process is checked, and processing is performed according to the fault, which is beneficial to rapidly performing fault location, and thus the test efficiency is improved.
Further, after step S6, the testing method in this embodiment further includes step S7: and determining an NFS sharing maximization value according to the actually mounted NFS sharing quantity.
And if the script stops midway in the running process, the test is unqualified. At this time, by checking the log file, the number of shared NFSs in the NFS sharing maximization test process can be determined, which is beneficial to further understanding the NFS sharing maximization, so that the next step of improving the fault in the sharing process is facilitated, and the test efficiency is improved.
In addition, before step S1, the present embodiment further includes step S0: and resetting the NAS cluster. Specifically, step S0 includes the following processes:
s01: clearing the original NAS cluster of the storage end;
s012: a new NAS cluster is created at the storage side.
Before the NAS cluster is subjected to the NFS sharing maximization test, other applications may have been created in the NAS cluster, and the sharing maximization test is directly performed on the storage nodes in the NAS cluster, the excessive other applications created before the tests may possibly interfere with the test results, and the NAS cluster is reset, so that the possible interference can be effectively avoided, and the accuracy of the test results is further improved.
In the following, taking the sharing maximization test of the storage product AS18000G2 AS an example, how to use the script to perform the NFS sharing maximization test is described in detail. The storage product AS18000G2 is a unified storage system with NAS functionality.
The storage end script and the client end script are compiled by the method, so that the scripts can be named conveniently for searching, if the storage end script is a Test1.sh script and is named as max _ nfs, the client end script can be named as a Test2.sh script.
The test1.sh script of the storage end comprises NAS cluster resetting, log file creating, storage pool creating, file system creating and NFS sharing. The method comprises the steps of clearing an original cluster by using a Relacenas command, creating a new cluster by using a ResetNasCluster command, creating a storage Pool by using an mtop mkmdiskgrp-easy auto-encrypt no-ext 1024-guiid 0-name Pool0-warning 80%, calculating the number of created file systems by using a count command, and creating NFS sharing by using a setnfs command.
The test2.sh script of the client can be realized by adopting the following method:
Figure BDA0001696541610000061
and executing the script Test2.sh, namely mounting the NFS sharing at the client, and recording the number of the mounted NFS sharing.
