    今天我们将前一小节中创建的 nfs-vol-xx attach 到Instance c1 上，这里重点分析 nova-compute如何将nfs-vol-xx attach到c1 上

    1、通过findmnt和mkdir测试和创建mount点
    2、mount NFS目录
    3、更新 Instance 的XML 配置文件，将volume 文件映射给Instance

    到此为止，关于cinder的内容就学习完了，总结一下：
     
    Cinder 作为OpenStack的块存储服务，为Instance提供虚拟磁盘。本章我们首先学习了Cinder的架构，然后讨论了Cinder的各个服务组件，最后通过使用场景详细分析了Volume的各种操作。
     
    操作中详细日志和截图可以帮助我们更好的理解Cinder内部运行机制，并为故障分析提供了非常有益的线索。
