I'm using Fio to run to raw devices in both Linux & Windows, one thing that I am unable to do is to specify an LBA range to run to. I know that there are the 'zonesize' and 'zoneskip' arguments, but I'm struggling to see how they work. In essence I would like to have a number of jobs running to different parts of the disk. In a basic example: from LBA 0 to 1/2 of MaxLBA I would like to run a sequential workload and from 1/2 MaxLBA+1 to MaxLBA I would like to run a random workload. Can this be done with existing arguments?
