Public bug reported: 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. Cinder trace: http://paste.openstack.org/raw/619767/ Among others, Cinder NFS backends are affected by this, as per the following Cinder NFS CI logs: http://logs.openstack.org/21/498321/5/check/gate-tempest-dsvm-full-devstack-plugin-nfs-nv/b8bca96/logs/screen-c-vol.txt.gz?level=ERROR ** Affects: nova Importance: Undecided Status: New ** Tags: api cells volumes ** Tags added: api cells volumes -- You received this bug notification because you are a member of Yahoo!
