Upon further discussion with the NetApp driver team and in light of [0] merging, the cluster-cinder-volume config has become non-functional for the moment as the driver does not support ACTIVE-ACTIVE [1] and the cinder code will not allow the driver to start in a clustered mode without supporting ACTIVE-ACTIVE [2].

Overview
The cinder charm is the Openstack block storage (i.e: Volume) service, whereas the cinder-netapp charm works as a subordinate of cinder, implementing a backend based on NetApp.
Note
: The cinder-netapp charm is supported starting with Openstack Queens.
Usage
Configuration
This section covers common and/or important configuration options. See file config.yaml for the full list of options, along with their descriptions and default values. See the [Juju documentation][juju-docs-config-apps] for details on configuring applications.
netapp-storage-family
The storage family type that is used for the storage system. Can be ontap_cluster for clustering data ONTAP, or eseries.
netapp-storage-protocol
The SAN protocol to use. Can be either iscsi or NFS.
netapp-vserver
Specifies the virtual storage server name on the storage cluster.
netapp-server-hostname
The hostname or IP address for the storage server (can alternatively specify a proxy server).
netapp-server-port
The TCP port used to communicate with the storage server or proxy.
If it's not specified, it will be deduced: For ONTAP drivers, it will be 80 for HTTP and 443 for HTTPS; for E-series, it will be 8080 and 8443, respectively.
netapp-login
The username used to access the storage server or proxy.
netapp-password
The password used to authenticate the login option.
netapp-nfs-shares-config
Specifies a file that contains a list of NFS shares, each on its own line, to which the driver will attempt to provision Cinder volumes.
netapp-controller-ips
If the storage family is eseries, this option specifies a comma-separated list of controller hostnames or IP addresses
to be used for provisioning.
netapp-array-password
The password for the NetApp E-series storage array.
netapp-storage-pools
Specifies a comma-separated list of pool names to use.
use-multipath
Whether to use multipath for image transfer.
netapp-enable-multiattach
Specifies whether the driver should allow operations that involve multiple attachments to a volume.
volume-backend-name
The service name to present to Cinder.
Deployment
This charm's primary use is as a backend for the cinder charm. To do so, add a relation betweeen both charms:
juju add-relation cinder-netapp:storage-backend cinder:storage-backend
