Hi, I was trying to execute fio with the following job file, but I have some issues with it. [globals] rw=randrw size=10M ioengine=sync blocksize=4k numjobs=16 direct=1 iodepth=32 thread [thread1] filename=/dev/sdb stonewall [thread2] filename=/dev/sdc stonewall [thread3] filename=/dev/sdd stonewall After its completion in Disk stats I got util as : sdb: util=99.64% sdc: util=51.72% sdd: util=34.76% where as expected util for all 3 disks should be somewhat similar ( all 3 disks are of same size) But if I run fio using separate jobfile for every disk, then I am getting almost similar disk util for each disk (around util=98% for each disk). Pl let me know that if there is some problem with the fio or there is something wrong with my jobfile. Thanks and regards, Shrirang. -- 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
