Public bug reported: Description =========== When rbd_user and rbd_secret_uuid are set in nova.conf, they overwrite the values returned from Cinder in the connection_info object. Therefore both ephemeral storage in Ceph, and multiple Cinder volume Ceph backends can't be used at the same time.
Steps to reproduce ================== * In nova.conf, set rbd_user, rbd_secret_uuid, images_rbd_pool, etc. * Booting a VMs. SUCCESS * Try attaching a volume from a pool with different credentials than the ephemeral one. FAILS * Unset rbd_user, rbd_secret_uuid * Try attaching a volume from a pool with different credentials than the ephemeral one. SUCCESS * Try booting a VM. FAILS Expected result =============== Both ephemeral and multiple ceph backends should work at the same time. Actual result ============= Either ephemeral or multiple ceph backends works at the same time. https://github.com/openstack/nova/blob/4f91ed3a547965ed96a22520edcfb783e7936e95/nova/virt/libvirt/volume/net.py#L89-L95 Environment =========== 1.
