<p>The best way to proceed would likely be to propose a

<div dir="ltr">Hi Novaers and Cinders:
<div><br>
</div>
<div>Quite often application requirements would demand using
locally attached disks (or direct attached disks) for
OpenStack compute instances. One such example is running
virtual hadoop clusters via OpenStack.<br>
</div>
<div><br>
</div>
<div>We can now achieve this by using BlockDeviceDriver as
Cinder driver and using AZ in Nova and Cinder, illustrated
in[1], which is not very feasible in large scale production
deployment.</div>
<div><br>
</div>
<div>Now that Nova is working on resource provider trying to
build an generic-resource-pool, is it possible to perform
"volume-based-scheduling" to build instances according to
volume? As this could be much easier to build instances like
mentioned above.</div>
<div><br>
</div>
<div>Or do we have any other ways of doing this?</div>
