Sorry about randseed, looked at wrong link. The right one is http://git.kernel.dk/?p=fio.git;a=blob;f=HOWTO;h=0808cc3a07e0f53a62c3476b6789f47426917829;hb=HEAD -----Original Message----- From: fio-owner@xxxxxxxxxxxxxxx [mailto:fio-owner@xxxxxxxxxxxxxxx] On Behalf Of Ruvinsky, Konstantin Sent: Friday, May 08, 2015 9:04 AM To: Jens Axboe Cc: fio@xxxxxxxxxxxxxxx Subject: 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.
