I've added cinder and os-brick here as AFAICT this isn't a Nova issue
given the description in c#0 and logs in c#1.
The attempt by Cinder to retype the detached volume doesn't appear to
have encrypted anything.
This might be the result of another issue in os-brick when connecting
the volume to the underlying host but that isn't obvious from the
compute logs.
Can you reproduce this with DEBUG logs on the compute so we can see what
os-brick is doing?

Title:
Retype of non-encrypted root volume to encrypted fails
Status in Cinder:
New
Status in OpenStack Compute (nova):
Incomplete
Status in os-brick:
New
Bug description:
Description
===========
I tried to retype volume from unencrypted to encrypted one. That works fine
for non-root volumes, however it doesn't work when volume was/is root volume.
Steps to reproduce
==================
1. Create an instance with unencrypted root volume(select do not delete
volume on termination)
2. Delete instance
3. Retype left volume from deleted instance to encrypted one and wait till
retype will finish successfully
4. Launch an instance from this encrypted volume(increase original size by
+2GB)
Expected result
===============
New instance is started from encrypted volume
Actual result
=============
Instance fails to start. At horizon we can see an error message:

"/usr/lib/python2.7/dist-packages/nova/conductor/manager.py", line 610, in
