Dear Peter. Thank you for your bug report.

And the implementation matches the manpage. The following output shows how wierd this behavior is: % fio --name=rand-read --bs=4k --size=1GiB --iodepth=64 --runtime=10 -- rw=randread […] rand-read: Laying out IO file(s) (1 file(s) / 953MiB) […] Nonetheless it is still an upstream issue. So please, despite assuming what upstream might do or not do about it, help me by reporting this issue upstream. Please write to [email protected]. Please also cc me and Jens Axboe. Please also Bcc the bug report, so that the initial mail of the thread is recorded there. By forwarding it upstream you help me to rather invest my time into updating the package. I want to take time for it soon enough. I am subscribed to the fio mailing list… so I can followup. I do think it is good to fix this. Thank you,
