nova-computer显示如上错误，云硬盘无法挂在，求高手赐教。。。。

只说
Driver failed to attach volume 3b72e68d-6f36-4cbd-9094-80de1fc69b9b at /dev/vdb
这个错误没有太大意义，产生这个问题的原因也很多

楼主是按照文档还是什么，建议多参考，多对比

我是参考官方文档安装的，目前看日志，只发现在挂在云硬盘时nova-computer.log中会报这个错误。。。
云硬盘不能挂载到虚拟机上，创建云硬盘也不能加载镜像。。。。如果创建云硬盘时选择加载镜像，cinder-api.log会报这个错误：

是不是我的cinder模块配置有问题？但是我比较了官方文档没发现有什么错误。。。。求大神赐教。。。

应该某个配置项错了，特别留心驱动的配置。

大神，创建云硬盘时选择加载镜像，cinder-api.log会报这个错误：

这个是怎么回事？我觉得我的cinder配置有问题，但是我没检查出来错误。。。。

你的错误只能定位到通信问题，所以检测相关配置。

确保下面都是正确

[DEFAULT]
...
auth_strategy = keystone

[keystone_authtoken]
...
auth_uri = http://controller:5000/v2.0
identity_uri = http://controller:35357
admin_tenant_name = service
admin_user = cinder
admin_password = CINDER_PASS



[DEFAULT]
...
my_ip = 10.0.0.41

[DEFAULT]
...
glance_host = controller

就这么点内容，细心就能解决。
上面只是给你举例，根据自己的实际情况修改

详细参考
openstack【juno】入门 【cinder篇】二十一：安装配置块存储节点（cinder）
http://www.aboutyun.com/thread-11681-1-1.html

问题以解决，是配置文件中my_ip配置错误，导致不能通信造成的
再次感谢给位大神的帮助~~~
