I've tried running ezfio.py on a linux system with an Intel NVMe. But it didn't output anything for blocksizes from 512-32k. Anything i'm doing wrong?

I've found the issue:

not run because block size 512 below iominsize 65536

Tried a Raid1 of NVMe behind a Avago 9440 controller and it reports:

# blockdev --getiomin /dev/sdb 65536
