No, you should not have to run rw=write first, you can run it as-is and fio should setup the files appropriately. Can you try and delete any leftover 4ktest.* files from the job, and then re-run the job and add --debug=file? Then just break it when it starts going and send the output in a reply here. -- Jens Axboe
