本节我们开始学习 Volume Detach 操作，就是将Volume从Instance上卸载下来。
 
 
1、向cinder-api 发送detach请求
2、cinder-api发送消息
3、nova-compute detach volume
4、cinder-volume删除target
 
volume detach 方法如下：
 
 
 
Detach 的操作是由 nova-compute 和 cinder-volume 共同完成
 
    1、首先nova-compute将volume从Instance上detach，然后断开与iSCSI target 的连接
            1.1、将缓存中的数据 flush 到 volume
            1.2、删除计算节点上 volume 对应的 iSCSI设备
            1.3、通过iscsiadmin的logout，delete操作断开与iSCSI target的连接
    2、最后cinder-volume删除volume相关的iSCSI target
