RE: achieving a workload to get specific unique duplicate blocks

Hi,

>If you want a truly different run everytime, you have a few options. One is to simply set randrepeat=0, then OS entropy will seed the random generators. Or you can use randseed= to set a specific seed, which would allow you to reproduce a specific run.

Two points:

1. Looks like randseed is not documented in HowTo (see http://git.kernel.dk/?p=fio.git;a=blob;f=HOWTO;h=005dac251dd202917fdb446ffec22d3126757f8c;hb=HEAD)
2. Maybe make sense to add to HowTo that randrepeat=1 is the default value.

Regards
Konstantin
