Hey I'm trying to create a mixed workload with FIO, basically, I'm trying to regulate the proportion of activity between jobs, what I'm trying to achieve is: oltp1_A - 10% of the total workload oltp1_B - 35% of the total workload oltp1_C - 35% of the total workload oltp1_D - 5% of the total workload oltp1_E - 15% of the total workload Which according to my calculation should translate to the following ratio: 2:7:7:1:3 However, when I add the "flow" per job according to my ratios above I'm getting a rate of 0 IOPS. Can anyone tell me what am I doing wrong? Thanks a lot! FIO config file: ioengine=libaio runtime=20 time_based norandommap group_reporting disk_util=0 continue_on_error=all rate_process=poisson group_reporting=1 [oltp1_A] direct=0 buffered=1 block=4k size=2G filename=/var/stuff/bla1 rw=randread iodepth=64 flow=2 [oltp1_B] direct=1 buffered=0 block=4k size=2G filename=/var/stuff/bla2 rw=randread iodepth=64 flow=7 [oltp1_C] direct=1 buffered=0 block=4k size=2G filename=/var/stuff/bla3 rw=randwrite iodepth=64 flow=7 [oltp1_D] direct=1 buffered=0 block=4k size=2G filename=/var/stuff/bla3 rw=read iodepth=64 flow=1 [oltp1_E] direct=1 buffered=0 block=4k size=2G filename=/var/stuff/bla3 rw=write iodepth=64 flow=3
