Thank you, Andrew and Jason for replying.
Jason,
Do you have a sample ceph config file that you can share which works with RBD and EC pools?
Thanks,
Pardhiv Karri

Correct, you can put an override in the "ceph.conf" file on your
Cinder controller nodes:
[client.cinder]
rbd default data pool = XYZ
You can also use Cinder multi-backend, each using a different CephX
user id, to support different overrides for different device classes.
