多雲數據管理深度實踐中 | 配置OpenSDS多後端（LVM、Cinder、Ceph）

上篇文章咱們經過Ansible安裝了OpenSDS，本文咱們繼續深刻了解OpenSDS，相信細心的童鞋會發現咱們上篇在簡短介紹OpenSDS的時候說到了能夠納管本地異構存儲，因此咱們本文將講述如何配置多後端，爲了充分展示咱們選擇了本地LVM，OpenStack的Cinder以及Ceph分佈式存儲做爲多後端來測試。

LVM咱們在上文安裝的時候已經默認配置了，Cinder和Ceph的話必須保證兩個存儲環境已經存在，同時保證OpenSDS節點與他們可以網絡互通。

配置多後端

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

安裝Ceph-Commd依賴

apt-get install ceph-common -y

#同時把Ceph環境的ceph.conf和ceph.client.admin.keyring拷貝到OpenSDS環境的/etc/ceph下

ceph -s

檢測下是否成功

配置完成以後咱們到Dashboard能夠看到多個後端已經展現出來了，有時候可能不顯示，可是數據已經顯示了，這多是個bug，我已經提交給社區了。

https://github.com/sodafoundation/opensds/issues/1240

接下來咱們到Dashbord配置Cinder和Ceph的profile

建立Volume測試下是否能夠

OK，能夠看到我建立了三個測試的卷，均已成功，那個default就是lvm。

接下來咱們在增長一個Ceph 對象存儲,操做步驟是在首頁點擊那個添加按鈕，而後配置rgw相關信息。
