Ok, what is --thread=1 ?  (it means it will create one thread to handle the
IO ?)


./fio --randrepeat=1
--ioengine=/home/oza/SPDK/spdk/examples/nvme/fio_plugin/fio_plugin
 --direct=1 --gtod_reduce=1 --thread=1 --name=readtest
--filename=0000.01.00.00/1
 --bs=4096   --iodepth=128 --size=4G --readwrite=read

With that it went ahead but at the end it says "requested device can not be
used"
I don’t think actual data transfer took place.

Hi Oza,

Please add —thread=1.  I will push a patch shortly that documents this
option for the SPDK plugin and checks for it at runtime.

Regarding your patches, you can submit them as a pull request to the SPDK
GitHub project.  See http://www.spdk.io/development/ for more details.

Thanks,

-Jim
