Comment(by PierreOssman):

 The problem is indeed that the old block device is still around. The
 python script datastore-service is keeping some files open on the old
 device, preventing it from being properly released. Killing the service
 allows the new block device to function correctly.

 Three possible solutions:

 1. Figure out why the block layer is wedging a new queue because of an old
 one lingering around.

 2. Get in the new fancy "revoke" patches that kill off open fd:s.

 3. Get datastore-service to not keep files open when it isn't actively
 using them.
