Description of drawings

Fig. 1 is a flow chart of the general idea of a method for stress testing RAID cards and hard disks applicable to customer sites.

Implementation

A method for stress testing RAID cards and hard disks applicable to customer sites according to the present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, a method of the present invention applicable to RAID card and hard disk stress testing at the customer's site, by modifying the program under the conf folder, and running the automatic batch script, the pressure can be performed in the specified folder or partition The test is applicable to most Linux systems. After the test is completed, the test result is automatically saved, and the pressure of the RAID card and hard disk can be adjusted as needed.

Pre-work:

Obtain the root authority of the Linux system on the client machine. Move the fio_td_test.tar.gz file to the specified directory under the system, and decompress the file.

Confirm the folder or partition specified by the customer, and evaluate the pressure of the RAID card and hard disk according to the customer's specific application, so as to prevent the customer's machine from running and hanging due to excessive pressure.

method script

The main body of the method described in this article executes three parts cyclically. The first part is to modify the parameters of the program under the conf folder according to the site situation to ensure that it will not affect the customer's application. The second part is to execute the batch file and perform a stress test. The third part, the end of the test, collect the test results.

(1) The following describes the main script of the first part, how to modify various parameters,

#ConfigFileforrandread-256k

[global]

ioengine=libaio

direct=1

runtime=300

iodepth=20

rw=randread

bs=256k

loops=10

group_reporting

[randread-256k-0]

filename=/corefiles/temp

size=15g

The randread-256k program is one of the programs under the conf folder, which represents the size of the random read module is 256k, and this is used as an example for illustration.

The program can be adapted to customer site tests by modifying the following parameters:

runtime=300 the running time of each small module

iodepth=20 The size of hard disk pressure can be changed according to the application environment, the smaller the value, the smaller the pressure

The filename=/corefiles/temp equal sign indicates the location where the stress test is to be performed, and temp needs to be added after the partition and folder, otherwise it cannot run. This address represents the stress test under the corefiles directory under the root directory

size=15g indicates the size of the space used by the pressure, if it is too small, it may cause the test time to fail to reach the specified time

After modifying the program according to the customer's site application, save and exit, so that the pressure test can be performed at the designated location.

(2) The second part, execute the batch file and perform the stress test,

Execute the automatic batch script auto_fio_all.sh under the fio folder, and then start the RAID card and hard disk stress test.

The content of auto_fio_all.sh is as follows:

lsconf>>conf.txt

foriin `catconf.txt`; do ../fio $i; done

Executing this automatic running script will test various test modules under the conf folder, and the test results will be printed on the screen, or saved to the result directory by command.

The program ends.

(3) The third part, the end of the test, collect the test results,

The test results will be printed to the screen, and can also be saved to the result directory by command.

The following is the test result of read-4k
