Public bug reported: In microversion v2.20, Nova allows to attach/detach volume on server in shelved or shelved_offloaded state.
When server is in shelved_offloaded state, it means server is not on any host. And volume attach operation is done directly via cinder. In that case device volume mount will be defered until the instance is unshelved. Which is valid case and all fine till here. Now issue is if users does the list attachments for server in shelved_offloaded state, it return the attachements without 'device' But Show volume attachment throw exception as there is no mount point for that attachment - https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/volumes.py#L289 List and show attachments should be consistent for server in shelved_offloaded state. Although error message if volume not mount - "volume_id not found: %s" does not sounds very nice here for other case too. ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
