Hi all,

I created an encryption type, and create a volume in Ceph with the volume type.
>> cinder encryption-type-create

But failed to attach it to a VM. The error message shows that no device_path in connection_info.

^[[01;31m2015-07-30 05:55:57.117 TRACE oslo_messaging.rpc.dispatcher ^[[01;35m^[[00m    self.symlink_path = connection_info['data']['device_path']^M
^[[01;31m2015-07-30 05:55:57.117 TRACE oslo_messaging.rpc.dispatcher ^[[01;35m^[[00mKeyError: 'device_path'

Two questions:
1. Is it not supported to create volume in Ceph with encrypted volume type?
2. If yes, should we prohibit to create a Ceph volume with encrypted volume type.

Best wishes
