多云数据管理深度实践中 | 配置OpenSDS多后端(LVM、Cinder、Ceph)

上篇文章咱们经过Ansible安装了OpenSDS,本文咱们继续深刻了解OpenSDS,相信细心的童鞋会发现咱们上篇在简短介绍OpenSDS的时候说到了能够纳管本地异构存储,因此咱们本文将讲述如何配置多后端,为了充分展示咱们选择了本地LVM,OpenStack的Cinder以及Ceph分布式存储做为多后端来测试。git


LVM咱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节点与他们可以网络互通。github


配置多后端express

vi /etc/opensds/opensds.confapache

[ceph]后端

name = ceph网络

description = This is a ceph backend serviceapp

driver_name = cephless

config_path = /etc/opensds/driver/ceph.yamldom


[cinder]分布式

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


配置完成以后咱们到Dashboard能够看到多个后端已经展现出来了,有时候可能不显示,可是数据已经显示了,这多是个bug,我已经提交给社区了。

接下来咱们到Dashbord配置Cinder和Ceph的profile

建立Volume测试下是否能够

QQ20200228-102444@2x.png

OK,能够看到我建立了三个测试的卷,均已成功,那个default就是lvm。


接下来咱们在增长一个Ceph 对象存储,操做步骤是在首页点击那个添加按钮,而后配置rgw相关信息。
