Parameter Issue with 'ratemin'...

Parameter Issue with 'ratemin'...

[FIO-User-KKV]

Hi, I am using Fio 2.2.8.
I have an issue when setting the parameter 'ratemin'.
It only accepts '0'!
no matter what non-zero values I set, 

e.g., 
sudo fio -name "SOURCE"  -numjobs 1  -bs 1M   -rw write -direct 1 -runtime 
50 -filename=/dev/vdb  -prio 0 -ratemin=1K

I will end up quickly with "fio: minimum rate exceeds rate"!
Could anyone know what's wrong there?

Thanks!

Hey,

The value of ratemin needs to be an int.  If you want 1000, you need to enter as 1000, not 1K.

Hi, thanks for the quick reply.
I also tried 1000, or 1, or 100 whatever...
It didn't work...
I always got "fio: minimum rate exceeds rate".
only 0 works.....

ratemin is meant to be used with rate. Say you set rate at 5mb/s, and 
you set a ratemin at 2mb/s. This means that fio will attempt to run at 
5mb/s, and it will fatally fail if it can't maintain 2mb/s. Setting 
ratemin without rate has no real meaning, which is why it errors out.
