Background
Currently, when the services of one data center are completely unavailable, service recovery can be performed from a data center that is located remotely. However, when the data center suffers from a failure or disaster, such as a power failure of the whole building and a short time difficult recovery, etc., the enterprise will have immeasurable loss due to the risk of service interruption and even data loss. In order to solve the above problems, a disaster recovery solution for a dual-active data center is proposed in the related art, and the disaster recovery solution for the dual-active data center provides data protection across data centers, that is, when a data center in a certain area fails, a data center in another area can quickly recover services such as calculation and storage. In general, in a double-activity scenario, two data centers exist in different areas of the same city, which belong to different available domains in a double-activity cluster, and when one available domain fails completely, the other available domain can still provide services, so that disaster tolerance capability at the level of the available domain is obtained. Meanwhile, in the dual-active cluster, in order to ensure that the main selection class service normally operates and the service is automatically switched in the primary and secondary available domains, an additional arbitration site needs to be deployed, the site only participates in the main selection algorithm and does not store any data, and the arbitration node is stored in a third-party data center so as to ensure that the environment of the available domain is not influenced.
In a double-active scenario, the current stability test is mainly based on two verification aspects, namely network layer verification for detecting the link state between available domains and verifying the link stability, and functional layer verification for performing health check on each node service. But in the related test technology, only the stability of the link and the service operation state of the node are ensured.
In view of the above problems, no effective solution has been proposed.

Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a disk testing method, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
FIG. 1 is a flow chart of a disk testing method according to an embodiment of the present invention, as shown in FIG. 1, the method includes the following steps:
step S102, starting a virtual disk to read and write data;
step S104, recording the read-write speed of the virtual disk read-write data and the bandwidth of the virtual disk read-write data;
step S106, obtaining a plurality of fluctuation rates of the read-write data of the virtual disk according to the read-write rate and the bandwidth;
and S108, obtaining a test result of the running state of the virtual disk according to the plurality of fluctuation rates.
Through the steps, the read-write rate of the virtual disk when reading and writing data and the bandwidth of the virtual disk when reading and writing data are recorded, the recorded read-write rate and the bandwidth are compared, a plurality of fluctuation rates of the virtual disk when reading and writing data can be obtained, the running state of the virtual disk can be reflected through the fluctuation rates, and the purpose of verifying the running stability of the virtual disk is achieved.
As an optional embodiment, the virtual disk is started to read and write data, where the virtual disk may be a virtual machine, and when the virtual disk is started to read and write data, the read and write data operation of the virtual disk may be executed using a performance test FIO tool, so as to test the performance of the disk device. It should be noted that, before starting the virtual disk to read and write data, the operating system of the virtual disk may be determined, and in the case that the operating system is a Linux operating system, a storage device with a predetermined capacity is mounted in the virtual disk, so as to ensure that the operation of reading and writing data of the virtual disk can be started smoothly.
As an optional embodiment, the read-write rate of the virtual disk for reading and writing data and the bandwidth of the virtual disk for reading and writing data are recorded, and the operating state of the virtual disk can be reflected by the read-write rate and the bandwidth of the virtual disk for reading and writing data. The read-write speed and the bandwidth of the virtual disk read-write data can be represented by IOPS data and BW (bandwidth) data, and the read-write speed and the bandwidth can obviously show the running performance of the virtual disk and the running state of the virtual disk. When the running state of the virtual disk is reflected according to the read-write speed and the bandwidth, a plurality of fluctuation rates of the read-write data of the virtual disk are obtained according to the read-write speed and the bandwidth, and the test result of the running state of the virtual disk is obtained according to the difference of the fluctuation rates. The running condition of the virtual disk can be reflected more accurately by judging through a plurality of fluctuation rates, and further the stability of the application layer is reflected.
As an alternative embodiment, when recording the read-write rate of the virtual disk for reading and writing data and the bandwidth of the virtual disk for reading and writing data, the recording may be performed in a predetermined periodic manner, for example: and recording the read-write rate of the virtual disk read-write data and the bandwidth of the virtual disk read-write data in a preset period to obtain a plurality of read-write rates of the virtual disk read-write data in a plurality of periods and a plurality of bandwidths of the virtual disk read-write data. The predetermined period may be a periodic period, for example, after the virtual disk starts to read and write data, recording is performed at intervals of 2 minutes, 10 minutes, 1 hour, and the like. In the recording process, comparing all recorded read-write rates and bandwidths so as to obtain the read-write rates and the fluctuation conditions of the bandwidths recorded at different times, namely obtaining a first difference between each read-write rate and other read-write rates in a plurality of recorded read-write rates and a second difference between each bandwidth and other bandwidths in a plurality of recorded bandwidths, and obtaining a plurality of fluctuation rates of the virtual disk for executing read-write data operation according to the first difference and the second difference, wherein the fluctuation rates can reflect the fluctuation conditions of the read-write rates and the bandwidths, and the differences can be embodied in the form of differences. For example, in the above illustrated cycle, the read/write rate and the bandwidth recorded at the 2 nd minute are calculated respectively, and the difference between the read/write rate and the bandwidth recorded at the 10 th minute and the 1 st hour is calculated, and the fluctuation rate of the read/write rate and the bandwidth is further calculated by the difference, so as to reflect the fluctuation conditions of the read/write rate and the bandwidth. The running state of the virtual disk can be reflected more intuitively and accurately.
As an alternative embodiment, obtaining the test result of the virtual disk operating state according to the plurality of fluctuation rates may include the following cases: and obtaining a test result of the stable operation of the virtual disk under the condition that the fluctuation rates are less than or equal to the first preset threshold, namely, the operation of the virtual disk is considered to be stable under the condition that the fluctuation conditions of the read-write speed and the bandwidth are relatively gentle. And obtaining a test result of the virtual disk running instability under the condition that the fluctuation rates are larger than a first preset threshold value, namely, the test result shows that the virtual disk running instability is considered under the condition that the fluctuation conditions of the read-write speed and the bandwidth are large. In the case that the fluctuation rates are larger than a first preset threshold value, namely in the case that the operation of the virtual disk is considered to be unstable, after the test result that the operation of the virtual disk is unstable is obtained, the method also comprises the case that the fluctuation rates are larger than a second preset threshold value, in the case, the test result that the operation of the virtual disk fails is obtained, namely, the fact that the virtual disk is considered to have a failure in the operation process is shown in the case that the fluctuation conditions of the read-write rate and the bandwidth are large. The first predetermined threshold and the second predetermined threshold may be specifically set according to actual experience and a scene. The second predetermined threshold is greater than the first predetermined threshold. By comparing the threshold values, the running state of the virtual disk can be reflected clearly, so that the stability of the application layer can be reflected.

In view of this, an optional embodiment of the present invention provides a method for testing dual-active stability, which detects the running state of a virtual disk service on each node, and solves the problem that in a related testing method, only depending on functional layer verification and network layer verification, if both verification passes, a dual-active scenario may have unstable service running, and can verify dual-active stability more safely, more timely, and more comprehensively, and discover problems of related application layers such as unstable service. And verifying the double-activity stability from the whole double-activity technical system solution level. The optional embodiment of the invention judges the stability of the application layer by continuously writing FIO into each node virtual disk and recording the IOPS rate and BW data in different time periods.
