That is just how the verify mode works. It is, and it's quite possible to craft a job that won't verify (even though fio warns you about it, as you said). If you have separate IO threads stomping on each others writes, it won't verify. That's mostly a "doctor it hurts when I..." situation. FWIW, Luis, your email gets marked as spam. I think you need to check settings. I only see John's replies. -- Jens Axboe
