　　cinder创建的volume被删除时一直处在‘Error-Deleting’的状态
　　首先停掉所有关于cinder的服务
　　通过lvremove删掉僵尸实例，再从数据库中删除，一般需要删2个地方：volumes表和iscsitarget表
　　2.cinder创建实例之后直接报error
　　log显示信息

从log中很难发现是什么地方错误了，因此首先先看cinder服务是否都是正常的，　　
　　发现iscsi-network-interface没有启动，启动之后发现还是创建失败。
　　查看配置文件中iscsi_helper配置的是什么，cinder有2种挂在方式tgtadm和ietadm(iscsi)
　　如果配置了一种看另外一种的服务是否在运行，我配置的是ietadm，因此禁用tgt服务。
