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.
