Flexible I/O Tester

Fio was originally written to save me the hassle of writing special test case programs when I wanted to test a specific workload, either for performance reasons or to find/reproduce a bug. The process of writing such a test app can be tiresome, especially if you have to do it often. Hence I needed a tool that would be able to simulate a given I/O workload without resorting to writing a tailored test case again and again.

A test work load is difficult to define, though. There can be any number of processes or threads involved, and they can each be using their own way of generating I/O. You could have someone dirtying large amounts of memory in a memory mapped file, or maybe several threads issuing reads using asynchronous I/O. fio needed to be flexible enough to simulate both of these cases, and many more.

Fio spawns a number of threads or processes doing a particular type of I/O action as specified by the user. fio takes a number of global parameters, each inherited by the thread unless otherwise parameters given to them overriding that setting is given. The typical use of fio is to write a job file matching the I/O load one wants to simulate.

 

Container running as Server, so go to console for enter commands :

 

Test file random read/writes

fio --directory=/mnt/cache_ssd --size=1GB --direct=1 --rw=randrw --bs=4k --ioengine=libaio --iodepth=4 --runtime=30s --numjobs=1 --time_based --group_reporting --name=iops-test-job --eta-newline=1

 

Test file sequential reads

fio --directory=/mnt/cache_ssd --size=1GB --direct=1 --rw=read --bs=4k --ioengine=libaio --iodepth=4 --runtime=30s --numjobs=1 --time_based --group_reporting --name=iops-test-job --eta-newline=1

 

Test file sequential write

fio --directory=/mnt/cache_ssd --size=1GB --direct=1 --rw=write --bs=4k --ioengine=libaio --iodepth=4 --runtime=30s --numjobs=1 --time_based --group_reporting --name=iops-test-job --eta-newline=1

examples can be dowloaded to "/mnt/user/appdata/Fio/examples" , then edit with your needs and copy to "/mnt/user/appdata/Fio"

and Run the job using the following command:

fio /fio/randomread.fio
