Your drive seems to be 2GB?? Is this correct? It's trying to do a test of size 0-bytes which is going to crap out either in fio or in the python when it hits a div-by-0 or equivalent.

I think testing on a normal sized drive might be all that's needed. Can you re-run with a normal-sized volume?

commented

I use scsi_debug scsi device like this:

modprobe scsi_debug dev_size_mb=2048

This is a block device that is compatible with SCSI.

commented

That may be, but 2GB is not enough to run the test. Use at least 10GB.

However ezfio is intended to test real SSDs or HDDs, or at least ones of normal sizes (1-30TB) so any results you get on a 10GB volume will not be useful or interesting...
