Attempt to attach volume to an invalid device
$ nova volume-attach bar c3e6b09b-88c8-4fb3-a115-b5921eb0b6f0 /dev/vda
ERROR: The supplied device path (/dev/vda) is in use. (HTTP 400) (Request-ID: req-d2cfbc33-dbfc-4034-82f0-85b5de3e3fa7)
Exceptions are correct but we get a large traceback in the logs:
