Hi, I'm trying to run a reader process and writer process and give higher priority to the reader. I ran into an issue below. Am I missing something? Thanks in advance for your inputs! David root@android:/sdcard/tmp # fio random-readwrite2-test.fio Bad option <prioclass=2> fio: job random-write dropped 1|root@android:/sdcard/tmp # cat random-readwrite2-test.fio ; parallel random read and write with read priority [global] size=128m bs=4k directory=/sdcard/tmp/test randrepeat=1 [random-write] rw=randwrite prioclass=2 [random-read] rw=randread prioclass=1 -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
