Hi, I’m trying to do both Random and Sequential operations simultaneously in one job. In specific, I would like to do Sequential Writes and Random Reads in parallel. Here is what I have got so far. [global] ioengine=libaio disable_slat=1 disable_lat=1 thread direct=1 [job2] stonewall bs=128kb,4kb ba=128kb,4kb rw=randrw iodepth=256 runtime=5s time_based=1 log_avg_msec=0 randrepeat=0 norandommap refill_buffers write_bw_log=job2 write_iops_log=job2 write_lat_log=job2 bs_is_seq_rand=1 rwmixread=1 percentage_random=50 I’m assuming the above job would do 128k Sequential and 4k Random (50% each), writes and reads (with reads=1%) combined for both Sequential and Random, for 5s. I’m still not able to do just Sequential Writes and Random Reads alone in parallel. Thanks, Prabhu
