Hi Novaers and Cinders: 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.
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. 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. Or do we have any other ways of doing this?
