Title:
Static Ceph mon IP addresses in connection_info can prevent VM startup
Status in OpenStack Compute (nova):
In Progress
Status in nova package in Ubuntu:
In Progress
Bug description:
The Cinder rbd driver extracts the IP addresses of the Ceph mon servers from the Ceph mon map when the instance/volume connection is established. This info is then stored in nova's block-device-mapping table and is never re-validated down the line.
Changing the Ceph mon servers' IP adresses will prevent the instance from booting as the stale connection info will enter the instance's XML. One idea to fix this would be to use the information from ceph.conf, which should be an alias or a loadblancer, directly.
