Public bug reported: Snapshotting instances that use the RBD Glance image backend fails if Glance is configured to use multiple stores.
Trace: http://paste.openstack.org/raw/804113/ The reason is that the Nova Libvirt driver creates the RBD snapshot directly and then updates the Glance image location. However, Nova isn't aware of the Glance store, so this information won't be included. Glance will error out when trying to add a location that doesn't include the store name when multiple stores are enabled, or even if there's a single one passed through the "enabled_backends" glance option. https://github.com/openstack/nova/blob/68af588d5c7b5c9472cbc2731fee2956c86206ea/nova/virt/libvirt/imagebackend.py#L1144-L1178 https://github.com/openstack/nova/blob/68af588d5c7b5c9472cbc2731fee2956c86206ea/nova/image/glance.py#L701-L702 https://github.com/openstack/nova/blob/68af588d5c7b5c9472cbc2731fee2956c86206ea/nova/image/glance.py#L555-L561 https://github.com/openstack/python-glanceclient/blob/3.3.0/glanceclient/v2/images.py#L472 https://github.com/openstack/glance/blob/b5437773b20db3d6ef20d449a8a43171c8fc7f69/glance/location.py#L122-L129 https://github.com/openstack/glance_store/blob/ae9022cd3639bf3d0f482921d03b2b751f757399/glance_store/location.py#L83-L113 The image store should probably be fetched by either Nova or Glance. ** Affects: glance Importance: Undecided Status: New ** Affects: nova Importance: Undecided Status: New ** Tags: ceph libvirt ** Tags added: ceph ** Also affects: glance Importance: Undecided Status: New ** Summary changed: - instance snapshots fail when using rbd + nova instance snapshots fail when using rbd -- You received this bug notification because you are a member of Yahoo!
