What am I doing wrong in this incantation? I was under the impression that everything preceding the first "--name" was like a "globals" section in a command file, yet, no matter what number follows "--rwmixread" in the following incantation, it allways does a 50/50 mix: fio --rw=randrw --bs=8k --rwmixread=0 --iodepth=256 --output=/tmp/fio.out.txt --group_reporting --sync=0 --direct=1 --randrepeat=0 --softrandommap=1 --ioengine=libaio --loops=10000 --runtime=60 \ --name=test0 --filename=/dev/sda --numjobs=2 --size=16091503001 \ --name=test1 --filename=/dev/sdb --numjobs=2 --size=16091503001 \ --name=test2 --filename=/dev/sdc --numjobs=2 --size=16091503001 \ --name=test3 --filename=/dev/sdd --numjobs=2 --size=16091503001 \ --name=test4 --filename=/dev/sde --numjobs=2 --size=16091503001 \ --name=test5 --filename=/dev/sdf --numjobs=2 --size=16091503001 \ --name=test6 --filename=/dev/sdg --numjobs=2 --size=16091503001 \ --name=test7 --filename=/dev/sdh --numjobs=2 --size=16091503001 How do I get the --rwmixread to work up-front?
