这一篇介绍了如何将旧 OpenStack 实例创建的 Ceph Volume 添加到新的 OpenStack 实例中.


目录

  1. 同一个 Ceph Cluster 内转移
  2. 不同 Ceph Clusters 间转移
  3. 参考

同一个 Ceph Cluster 内转移

#### On old openstack controoler node
$ openstack volume show 5029f6d0-753b-417d-991d-2ea4f61bbe96
## or
$ cinder show 5029f6d0-753b-417d-991d-2ea4f61bbe96
...
| os-vol-host-attr:host          | controller01.ihep.ac.cn@ceph-default#ceph-default |
...
#### On new openstack controller node
$ cinder manage --name=newdata300 controller01.ihep.ac.cn@ceph-default#ceph-default volume-5029f6d0-753b-417d-991d-2ea4f61bbe96

不同 Ceph Clusters 间转移

参考

  1. Volume migration between OpenStacks Clusters
  2. import existing cinder volumes from ceph into newly installed openstack
