cinder卷删除不掉解决方法

现象：创建的卷虚机人为或代码干预导致虚机删除掉但是卷还在in-use的状态，此种情况想要detach卷报错虚机不存在，想删除卷也删不掉

原因为： nova删除虚机时自动分离卷，但由于rabbitmq或者其他原因导致卸载卷不成功，但nova未能对此结果处理，还是将虚机删除掉了，就会导致这种情况

#可以发现虚拟机已经删除掉，但是卷还在挂载着
[root@controller ~]# openstack volume list

#第二次删除还是导致失败
[root@controller ~]# cinder delete 77664599-c422-4f32-afe8-49baa5f8c9f2
Delete for volume 77664599-c422-4f32-afe8-49baa5f8c9f2 failed: Invalid volume: Volume status must be available or error_restoring \

ERROR: Unable to delete any of the specified volumes.

解决方法如下：

1. 在控制节点先show一下问题卷 加上debug 调取接口

cinder --debug show 77664599-c422-4f32-afe8-49baa5f8c9f2
#获取到的链接
http://controller:8776/v3/6535a5a0ef0c4e9caa42912d02bd7d54/volumes/77664599-c422-4f32-afe8-49baa5f8c9f2

2. 获取token认证

openstack token issue
#获取的token值
gAAAAABexeM59k1IxnaprSQnMRf0eMI8lBD9Q5jlBC97A-8thQ8PFsljLuxqoGo98cnwPfOAbNny7r0T14etakmsL7Smfmjlb25frlSnSqG5mCZOp5chJ0OYtc7P2paGgjn6STlkGxFoaIH7lCe0ehwB-DjYWrCpjC-oH9Wrh1UwaE4Vvmf29rw

3. 最后要去数据库查询

volume_attachment表格中这个卷对应的挂载的 id

MariaDB [(none)]> use cinder
MariaDB [cinder]> select * from volume_attachment where volume_id='77664599-c422-4f32-afe8-49baa5f8c9f2';
#获取到的id值
5ed3a5ca-c6b3-4fcd-899a-146f3cf9db80

4. 将以上查询到的信息集成修复接口

curl -g -i -X POST http://controller:8776/v3/6535a5a0ef0c4e9caa42912d02bd7d54/volumes/77664599-c422-4f32-afe8-49baa5f8c9f2/action -H "User-Agent: python-cinderclient" -H "Content-Type: application/json" -H "Accept: application/json" -H "X-Auth-Token: gAAAAABexeM59k1IxnaprSQnMRf0eMI8lBD9Q5jlBC97A-8thQ8PFsljLuxqoGo98cnwPfOAbNny7r0T14etakmsL7Smfmjlb25frlSnSqG5mCZOp5chJ0OYtc7P2paGgjn6STlkGxFoaIH7lCe0ehwB-DjYWrCpjC-oH9Wrh1UwaE4Vvmf29rw" -d '{"os-detach": {"attachment_id": "5ed3a5ca-c6b3-4fcd-899a-146f3cf9db80"}}'

控制节点执行完此命令 重新查询该卷 已经变为了available状态 重新执行cinder delete id 删除掉就可以了；

[root@controller ~]# openstack volume list
