今天学习如何扩大volume的容量，为了保护现有的数据，cinder不允许缩小volume。
 
Extend 操作用于扩大Volume的容量，状态为Available的volume才能够被extend。如果volume当前已经attach给Instance，需要先detach后才能extend。extend实现比较简单，流程图如下：
 
 
1、向cinder-api 发送extend请求
2、cinder-api发送消息
3、cinder-scheduler选择合适的节点
4、cinder-scheduler将选择的存储节点信息发送出来
3、cinder-volume执行extend操作
