Title:
Nova assisted volume snapshots fails to find BDM in multi-cell
Status in OpenStack Compute (nova):
In Progress
Status in OpenStack Compute (nova) pike series:
Confirmed
Bug description:
When using separate databases for each Nova cell, nova assisted volume
snapshots always fail with the following error:
BadRequest: No volume Block Device Mapping with id
a10bd120-9b88-4710-bf6e-f1d34de87da2. (HTTP 400)
The reason is that the according API call does not include an instance
id, which is fetched from the BDM. At the same time, the BDM cannot
properly be retrieved since Nova doesn't know which cell to use,
looking for the BDM in the wrong DB.
