fio custom job

Create a file (you can change 'size' command of fio according to this file's size. Let's assume that the name of this file is 'seqRead'.

Create a new file and add following lines to the file. Let's name the file as "fio_script"

		
		[jobname]
		rw=randread
		size=14000
		bs=4090
		ioengine=sync
		numjobs=2
		thread
		filename=seqRead

We run fio script by using fio command:

 
		
		Syntax $fio <scriptname>
		Eg: $fio fio_script

Let's understand what "filename=xyz" line means:
- filename option specifies that fio should find file of this name and do file operations (such as random read by 2 threads (both threads will do random read separately) in this example) instead of creating its own jobfiles. </ul> </ul>
