Running FIO on Windows on given partition or raw device

[Neependra Khare <neependra.khare@xxxxxxxxx>]

Hi,

I want to run FIO on a given partition on Windows.  To do this I use
the "mountvol" command and get the volume names and
their mount points and then use them for "filename" option with FIO

For example for "E:\" get following from "mountvol" command.

    \\?\Volume{1277e70d-79a7-11e1-9fed-f04da2ef6fc9}\
        E:\

Then I run following commands:-

$ fio.exe   --name=baseline --rw=randwrite --direct=1 --size=1g
--iodepth=32 --blocksize=4096 --ioengine=windowsaio
--filename=\\.\Volume{1277e70d-79a7-11e1-9fed-f04da2ef6fc9}
--name=hddBaseline --stonewall

$ fio.exe   --name=baseline --rw=randwrite --direct=1 --size=1g
--iodepth=32 --blocksize=4096 --ioengine=windowsaio  --filename=E:\
--name=hddBaseline --stonewall

$ fio.exe   --name=baseline --rw=randwrite --direct=1 --size=1g
--iodepth=32 --blocksize=4096 --ioengine=windowsaio
--filename=E:\filename --name=hddBaseline --stonewall

In all these cases I do not see any IO happening on "E" drive using
"perfmon". All the IO happens on the root drive("C").

On Linux I can use "/dev/sda" , "/dev/sda1" etc.

I was expecting same on Windows.
Any help or pointers would be great.
