With fio in the latest versions, however, it creates eight separate log files. Is there a way to get fio to generate a log file for all 8 workers, instead of 8 separate files? That is untenable. I had to go back to 2.1.8 to get a useable output. It's not like the data outputs are very friendly anyway, but with one file at least that data can easily be parsed and worked with. With a different file for each worker it is just ridiculous. > How do we get one output for all workers? > It would also be nice if we could just get one output with all of the numbers for the different workers combined, but that may be asking a bit much. Just getting them all in a workable file would be nice :) Lets back this up a bit. Your bug reporting _sucks_. Constructive criticism - look it up. You were even lazy enough to just reply to an old, totally unrelated email, instead of starting a new thread. So lets try this again. I'll even offer you some free hints. Find out where the change happened, see if there's reasoning there. If not, suggest a way to improve the situation. Or even just, constructively, suggest why the current behavior is a problem and offer your opinion on how it could be improved to make your life easier. Nobody on this list owes you anything, you need to earn it. -- Jens Axboe
