I don't know much about Cinder, but given this output: > 2014-08-21 16:42:49.847 1469 DEBUG > cinder.openstack.common.scheduler.filters.capabilities_filter [r...] > extra_spec requirement 'rbd' does not match 'quobyte' _satisfies_extra_specs > /usr/lib/python2.7/dist-packages/cinder/openstack/common/scheduler/filters/capabilities_filter.py:55 > 2014-08-21 16:42:49.848 1469 DEBUG > cinder.openstack.common.scheduler.filters.capabilities_filter [r...] host > 'controller@quobyte': free_capacity_gb: 156395.931061 fails resource_type > extra_specs requirements host_passes > /usr/lib/python2.7/dist-packages/cinder/openstack/common/scheduler/filters/capabilities_filter.py:68 > 2014-08-21 16:42:49.848 1469 WARNING cinder.scheduler.filters.capacity_filter > [r...-] Insufficient free space for volume creation (requested / avail): > 20/8.0 > 2014-08-21 16:42:49.849 1469 ERROR cinder.scheduler.flows.create_volume [r.] > Failed to schedule_create_volume: No valid host was found. I suspect you'll have better luck on the Openstack mailing list. :) Although for a random quick guess, I think maybe you need to match the "rbd" and "rbd-volumes" (from your conf file) strings? -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com > > here’s our /etc/cinder/cinder.conf > > — cut — > [DEFAULT] > rootwrap_config = /etc/cinder/rootwrap.conf > api_paste_confg = /etc/cinder/api-paste.ini > # iscsi_helper = tgtadm > volume_name_template = volume-%s > # volume_group = cinder-volumes > verbose = True > auth_strategy = keystone > state_path = /var/lib/cinder > lock_path = /var/lock/cinder > volumes_dir = /var/lib/cinder/volumes > rabbit_host=10.2.0.10 > use_syslog=False > api_paste_config=/etc/cinder/api-paste.ini > glance_num_retries=0 > debug=True > storage_availability_zone=nova > glance_api_ssl_compression=False > glance_api_insecure=False > rabbit_userid=openstack > rabbit_use_ssl=False > log_dir=/var/log/cinder > osapi_volume_listen=0.0.0.0 > glance_api_servers=1.2.3.4:9292 > rabbit_virtual_host=/ > scheduler_driver=cinder.scheduler.filter_scheduler.FilterScheduler > default_availability_zone=nova > rabbit_hosts=10.2.0.10:5672 > control_exchange=openstack > rabbit_ha_queues=False > glance_api_version=2 > amqp_durable_queues=False > rabbit_password=secret > rabbit_port=5672 > rpc_backend=cinder.openstack.common.rpc.impl_kombu > enabled_backends=quobyte,rbd > default_volume_type=rbd > > [database] > idle_timeout=3600 > connection=mysql://cinder:secret@10.2.0.10/cinder > > [quobyte] > quobyte_volume_url=quobyte://hostname.cloud.example.com/openstack-volumes > volume_driver=cinder.volume.drivers.quobyte.QuobyteDriver > > [rbd-volumes] > volume_backend_name=rbd-volumes > rbd_pool=volumes > rbd_flatten_volume_from_snapshot=False > rbd_user=cinder > rbd_ceph_conf=/etc/ceph/ceph.conf > rbd_secret_uuid=1234-5678-ABCD-…-DEF > rbd_max_clone_depth=5 > volume_driver=cinder.volume.drivers.rbd.RBDDriver > > — cut --- > > any ideas? > > cheers > Jens-Christian > > -- > SWITCH > Jens-Christian Fischer, Peta Solutions > Werdstrasse 2, P.O.
