Open Stack

I want to deploy Juno Devstack with my own cinder volume driver for my
client backend.

I am not getting my driver information updated in cinder.conf file
under "enabled_backends" in [DEFAULT] header.so cinder volume service
is not ruuning for my backend.
Any help or suggestion will be helpful.

Below are the steps i followed:

1)git clone https://github.com/openstack-dev/devstack.git

2)cd devstack

3)vi local.conf
