O050、Create Volume 操作 （Part I）
前面已经学习了Cinder的架构和相关组件，从本节开始详细分析 Cinder 的各种操作，首先讨论 Cinder 如何创建 volume。
Create 操作流程如下：
1、客户（可以是OpenStack 最终用户，也可以是其他程序）向 API（cinder-api）发送请求：帮我创建一个volume
2、API 对请求做一些必要处理后，向Messaging（RabbitMQ）发送了一条消息：让 Scheduler 创建一个volume
3、Scheduler （cinder-scheduler） 从 Messaging（RabbitMQ）获取到API发给他的消息，然后执行调度算法，从若干计算节点中选出节点A
4、Scheduler 向 Messaging 发送了一条消息：让存储节点A创建这个volume
5、存储节点A 的Volume（cinder-volume）从Messaging 中获取到Scheduler发给他的消息，然后通过 driver 在volume provider上创建volume
因为Create Volume操作比较复杂，我们分三次学习：
第一部分：cinder-api 的处理过程
第二部分：cinder-scheduler
第三部分：cinder-volume
向cinder-api发送请求
客户（可以是OpenStack最终用户，也可以是其他程序）向cinder-api发送请求：帮我创建一个volume。GUI上操作的菜单为 Project -> Volumes -> Volumes -> Create Volume
设置 volume 的 name 、type、size、availability zone 等基本信息
这里我们没有设置 Volume Source ，这样会创建一个空白的volume。点击 “Create Volume” 按钮。cinder-api 将接受到创建volume 的请求，可以在日志查看看到请求记录。
1、cinder api 接收到创建volume的请求，下面是访问请求接口的日志和请求的详细信息

3、cinder-api启动了一个Flow工作流 volume_create_api。Flow 的执行状态依次为：PENDING、RUNNING、SUCCESS，当前状态PENDING->RUNNING。该Flow会创建5个tasks，每个task也会经历PENDING、RUNNING、SUCCESS三个状态
