This article mainly introduces the use of linux fio command for disk stress testing and verification, the article is very detailed, has a certain reference value, interested friends must read it!

Fio is a very good tool for testing IOPS for stress testing and verification of disks. Disk IO is an important indicator for checking disk performance, which can be divided into two categories: read and write sequentially and randomly read and write according to the load. FIO is a tool that can generate many threads or processes and perform specific types of user-specified Icano operations. The typical use of FIO is to write and simulate job files that match the load of Icano. In other words, FIO is a multithreaded io generation tool that can generate a variety of IO patterns to test the performance of disk devices (including file systems, such as IO tests for network file system NFS).

Syntax format: fio [parameters]

Common parameters:

Reference example

Test random read and write:

[root@linuxcool] # fio-- filename=/bdata/test.big-iodepth=64-ioengine=libaio-direct=1-rw=randwrite-bs=4k-size=2G-numjobs=64-runtime=20-group_reporting-name=test-rand-write

Test sequence read:

[root@linuxcool] # fio-filename=/bdata/test.big-iodepth=64-ioengine=libaio-direct=1-rw=read-bs=1m-size=2g-numjobs=4-runtime=10-group_reporting-name=test-read

The test sequence is written:

Fio-- filename=/bdata/test.big-iodepth=64-ioengine=libaio-direct=1-rw=write-bs=1m-size=2g-numjobs=4-runtime=20-group_reporting-name=test-write above are all the contents of stress testing and verification of the disk using linux's fio command, thank you for reading!
