Hi all, I wanted to test some files.But i wanted to use size rather than nrfiles.The job file is: [global] rw=write directory=/media bs=64k size=500M [j1] filesize=256k But fio only created one file.If i used nrfiles,the size is ignored. So how to write which can do what i wanted? Jianpeng Thanks! ?韬{.n?????%??檩??w?{.n?????^n?■???h?璀?{?夸z罐?+€?zf"?????i?????_璁?:+v??撸?
