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.

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
Lisa

This is a known issue and was pointed out in the mailing list earlier
[1]. A change was made to make that fail fast and obvious now rather
than let users think they had encrypted rbd volumes.
The KeyError in nova should have a better exception raised with this
change [2].
nagyz is working on adding the encryption support for rbd to nova here [3].
