Nova无法Attach Cinder Volume， Caught error: 'volume'

在原来的基础上将nova-volume换成了cinder，一切安装好以后，服务均工作正常。通过Dashboard创建Volume能够成功，之后将Volume attach到instance时出现错误，查看日志发现在/var/log/nova/api.log下有如下错误日志：2013-02-25 15:30:08 INFO nova.api.openstack.wsgi [req-09239b09-97d1-4f5d-a9c3-15f60f33d877 c881ba5369ff40dbad6586b935c5515c 646a1ca8dcfa4ea5b0c7dc2d2d729f66] POST http://10.10.1.162:8774/v1.1/646a1ca8dcfa4ea5b0c7dc2d2d729f66/servers/c4381af1-49e2-43d8-be41-a2ee9c948c05/os-volume_attachments

查了很久，不知道这是什么原因引起的，请问有谁遇到过没有？
我的cinder配置如下：

auth_host = 10.10.1.162
auth_port = 35357

热切盼望有人能帮忙解答！！！openstacknovacindervolume

  2.   

    还要主要NOVA的配置文件与cinder相关配置如下：#volume_driver         = nova.volume.driver.ISCSIDriver
    #启用cinder
    volume_api_class       = nova.volume.cinder.API
    enabled_apis=ec2,osapi_compute,metadata
    #volumes_dir           = /etc/nova/volumes
    #volume_group          = vg_linux
    #volume_name_template  = volume-%s
    #iscsi_helper          = tgtadm
      

  3.   

    0、首先用fdisk -l 看看你创建的lv 是否真的存在
    1、检查tgt服务是否正常
    2、在/etc/tgt/tgrgets.conf  中有类似：include /etc/nova/volumes/*或者 include /etc/cinder/volumes/* 的配置条目。
    3、在 /etc/nova/volumes/ 或者 /etc/cinder/volumes/ 是否生成了你所创建lv的相关target配置文件
    5、如果以上都正常，可以在windows系统安装iSCSI Initiator 来挂接测试你的tgt服务你创建的lv。具体操作步骤不在详述。
    如果以上都正常。那么就要看是否nova的问题了！！！

    你说的东西都是正确配置好了的。我已经检查过了。
    我也怀疑是不是nova的问题，但是现在苦于找不到原因。
