Fio IOPS reported incorrectly in some cases

Fio IOPS reported incorrectly in some cases

[Yogi Wannabe]

Hi,

When I run fio like this: fio <config filename>

it reports the correct IOPS from beginning of the test. But when I run
fio like this,

fio --minimal --status-interval=1 <config filename>

the IOPS reported is about 150K lower than expected but gradually
ramps up and shows the correct value just before the test ends. Is
this a known issue? Is there a work around for this?

Thanks
Yogi

There's not enough detail to really comment - have you seen
https://github.com/axboe/fio/blob/master/REPORTING-BUGS ?. Which part
of the output in particular are you referring to in your comparisons?
Are you on the latest (2.99) version of fio?
