What parameters are you using? Here is a counterexample from a previous post that shows number_ios running and then the job terminating: fio --name=test_job --ioengine=libaio --direct=1 --rw=read --iodepth=1 --size=100% --bs=4k --filename=/dev/nvme1n1 --number_ios=8 Regards, Jeff -----Original Message----- From: fio-owner@xxxxxxxxxxxxxxx [mailto:fio-owner@xxxxxxxxxxxxxxx] On Behalf Of Prabhakaran Sent: Wednesday, November 22, 2017 2:47 PM To: fio@xxxxxxxxxxxxxxx Subject: Running for a specific number of IOs Hi, Is there a parameter in FIO that can be used to run for a specific number of IOs? I thought 'number_ios' might to this, but actually it does fill 1x of the drive usable space and exits.
