Comment 1 for bug 1502876

I just want to clarify, I was attempting to reproduce a bug in Nova and after cleaning up the volumes I'd created, in Horizon I received this error when I tried to delete the volume. I had not used Ceph, I just created a volume snapshot off of a volume I created off of the default cirros image. I think it's fair to say, this bug affects any volume with an associated snapshot.

From the command line, I ran "cinder delete foo" and got the message "Delete for volume foo failed: Invalid volume: Volume still has 1 dependent snapshots. (HTTP 400) (Request-ID: req-74c69b6d-f687-4738-b7c9-42bca6bf5a5c)
ERROR: Unable to delete any of the specified volumes." In the Horizon UI, logged in as admin, I received the error listed in this bug when I tried to delete that volume. Once I had this information from cinder in the CLI, I returned to Horizon. I deleted the volume snapshot and then I was able to delete the volume.
