# systemctllist-unit-files| grep cinder
openstack-cinder-api.service enabled ##用户接口
openstack-cinder-backup.service enabled ##备份
openstack-cinder-scheduler.service enabled ##调度

再创建一个cinderv2和上面一样

| 75a8f5bbf35a42a0bfcd2e6a0d4cea9c | RegionOne | http://115.29.107.17:8776/v2/%(tenant_id)s | http://115.29.107.17:8776/v2/%(tenant_id)s | http://115.29.107.17:8776/v2/%(tenant_id)s | 8fe36f49892447679bc5433b21591906 |

待测试 ceph做后端存储具体ceph配置 可看我前一篇glance
volume_driver = cinder.volume.drivers.rbd.RBDDriver
rbd_pool = cinder#ceph 卷名字
rbd_ceph_conf = /etc/ceph/ceph.conf
rbd_flatten_volume_from_snapshot = false
rbd_max_clone_depth = 5
rbd_stone_chunk_size = 4
rados_connect_timeout = -1
glance_api_version = 2
setfacl-m u:cinder:r-- /etc/ceph/ceph.client.admin.keyring##cinder可读
