When I use fio in 2.1.8 the write_iops_log command creates a singular log file, even with 8 workers. 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 :) -----Original Message----- From: Jon Tango [mailto:cheerios123@xxxxxxxxxxx] Sent: Tuesday, September 30, 2014 4:14 AM To: 'Andrey Kuzmin' Cc: 'Jens Axboe'; 'Sitsofe Wheeler'; fio@xxxxxxxxxxxxxxx Subject: RE: Limit LBA Range The same thing could be done by partitioning the SSD in the operating system with the desired partition size, and then running a time-based fio job against the partition. Basically, fio options offset/size should yield the same net result, but I'm always unsure on what is the actual effect of mixing size and time_based in a single job, and whether fio will wrap around the specified size to the specified offset if the job is time-based. HOWTO could have used some clarification on size/time_based interaction.
