多云数据管理深度实践中 | 配置OpenSDS多后端（LVM、Cinder、Ceph）
上篇文章我们通过Ansible安装了OpenSDS，本文我们继续深入了解OpenSDS，相信细心的童鞋会发现我们上篇在简短介绍OpenSDS的时候说到了可以纳管本地异构存储，所以我们本文将讲述如何配置多后端，为了充分展现我们选择了本地LVM，OpenStack的Cinder以及Ceph分布式存储作为多后端来测试。
LVM我们在上文安装的时候已经默认配置了，Cinder和Ceph的话必须保证两个存储环境已经存在，同时保证OpenSDS节点与他们能够网络互通。
配置多后端
vi /etc/opensds/opensds.conf
ceph
name = ceph
description = This is a ceph backend service
driver_name = ceph
config_path = /etc/opensds/driver/ceph.yaml
cinder
name = cinder
description = This is a cinder backend service
driver_name = cinder
config_path = /etc/opensds/driver/cinder.yaml
配置Ceph和Cinder的yaml文件
root@opensds:/etc/opensds/driver# cat ceph.yaml

安装Ceph-Commd依赖
apt-get install ceph-common -y
#同时把Ceph环境的ceph.conf和ceph.client.admin.keyring拷贝到OpenSDS环境的/etc/ceph下
ceph -s
检测下是否成功
配置完成之后我们到Dashboard可以看到多个后端已经展示出来了，有时候可能不显示，但是数据已经显示了，这可能是个bug，我已经提交给社区了。
https://github.com/sodafoundation/opensds/issues/1240
接下来我们到Dashbord配置Cinder和Ceph的profile
创建Volume测试下是否可以
OK，可以看到我创建了三个测试的卷，均已成功，那个default就是lvm。
接下来我们在增加一个Ceph 对象存储,操作步骤是在首页点击那个添加按钮，然后配置rgw相关信息。
