Hello Stackers,
I am testing manila manila.share.drivers.generic.GenericShareDriver with manila.share.drivers.generic.GenericShareDriver.
I created in my project an instance with nfs server and it is up and running.
In my manila.conf I have specified the instance id, use and password:

[locale]
share_driver = manila.share.drivers.generic.GenericShareDriver
driver_handles_share_servers = false
share_backend_name= locale
service_instance_user = manila
service_instance_passwod = manila
service_instance_name_or_id = 5b0fa246-e94b-4a84-b730-7066dfb31fb0
path_to_private_key=~/.ssh/id_rsa
path_to_public_key=~/.ssh/id_rsa.pub

I have also other backend with netapp drivers and they works fine.
The generic drivers reports:

Seems the instance I created is not available.
Please, any help?
