OpenStack部署(6)_块存储服务Cinder

OpenStack块存储服务为实例提供块存储。块存储API和调度程序服务通常运行在控制节点上，取决于所使用得驱动程序。卷服务可以运行在控制，计算节点或者独立得存储节点上。

(1)cinder-api
接受API请求，并将其路由到”cinder-volume”执行。
(2)cinder-volume
与块存储服务和cinder-scheduler进行直接交互。它也可以与这些进程通过一个消息队列进行交互。
(3)cinder-scheduler守护进程
选择允许存储提供节点来创建卷。其与nova-scheduler组件类似。
(4)cinder-backup守护进程
“cinder-backup”服务提供任何种类备份卷到一个备份存储提供者。就像”cinder-volume”服务，它与多种存储提供者在驱动架构下进行交互。
(5)消息队列
在块存储得进程之间路由信息。
