Migrating detached volumes works fine but it currently fails when they're attached. My cinder.conf looks like this: [DEFAULT] ... enabled_backends = standard,standard2 ... [keystone_authtoken] auth_uri = auth_url = auth_type = password project_domain_id = default user_domain_id = default project_name = service username = cinder password = ********************** memcache_security_strategy = ENCRYPT memcache_secret_key = ********************** memcached_servers =,, ... [standard] rbd_ceph_conf = /etc/ceph/ceph.conf rbd_user = cinder backend_host = rbd:volumes rbd_pool = volumes volume_backend_name = standard volume_driver = cinder.volume.drivers.rbd.RBDDriver rbd_secret_uuid = 827ef4dc-1441-4633-aaf0-16cd1ebffa07 [standard2] rbd_ceph_conf = /etc/ceph/ceph2.conf rbd_user = cinder2 backend_host = rbd:volumes rbd_pool = volumes volume_backend_name = standard2 volume_driver = cinder.volume.drivers.rbd.RBDDriver rbd_secret_uuid = 4d48e8c0-3557-424d-93e7-5b2f98a6f5ae First, it failed with something like "Endpoint not found" in one of the cinder logs. I could fix that by setting nova_endpoint_template and nova_endpoint_admin_template as suggested in one of the questions asked here. I set if equal to that is set in Keystone's service catalog which works fine: nova_endpoint_template = nova_endpoint_admin_template = Then I got a "key error" for "tenant_id". Checking the default value of these in the configuration reference, I found out it had to be "project_id" so I changed that to nova_endpoint_template = nova_endpoint_admin_template = It's weird since Keystone shows "tenant_id" and it works, but okay. I not got past the "key error" but hit the next message I cannot figure out: DiscoveryFailure: Could not determine a suitable URL for the plugin Of course, this line only doesn't help alot, so I uploaded everything I got after running openstack volume migrate --host rbd:volumes@standard2#standard2 vol1 in any of Cinder's logs on the controller: Any ideas are very welcome. cheers MathiasSat, 03 Jun 2017 06:25:42 -0500
