Yes, makes sense.

If you do I/O size change for the test cases nvme/032 and nvme/040, could you confirm the runtime reduction of the test cases? IIUC, the fio process stops due to process kill or an I/O error, then I/O size reduction will not change runtime of the test cases, I guess. IMO, --time_based --runtime=1m is good to ensure that fio runs long enough, even when nvme device size is configured with small size.

The fio process doesn't survive the reset and the deletion of the controller. > IMO, --time_based --runtime=1m is good to ensure that fio runs long enough, > even when nvme device size is configured with small size. I've updated the time to 'infinity' and added a 'kill $pid' after reset and delete. Though the process should be gone till then but making the test a bit more robust should hurt.

The fio jobs are supposed to run long in background during the test. Instead relying on a job size use explicit runtime for this. Signed-off-by: Daniel Wagner <dwagner@suse.de> --- tests/nvme/032 | 2 +- tests/nvme/040 | 3 ++- 2 files changed, 3 insertions(+), 2 deletions(-)
