OpenStack neutron删除网络设备出错解决办法

xiang8

　　目标：要删除外网Ext-Net2
　　直接删网络也会出错：因为有一个或多个端口在使用该网络

　　查看子网：删除子网会出错：一个或多个端口用了这个子网分配的浮动IP。

ERROR: No server with a name or ID of 'accd8dbf-0f16-4aec-b797-bbb33abcdc83' exists.
　　通过horizon查看，发现该浮动IP，没有被分配，但是用命令却查不到



root@controller:~# nova --os-tenant-name TenantA --os-username UserA --os-password password  --os-auth-url=http://localhost:5000/v2.0  floating-ip-list              
ERROR: The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-294eb77b-1615-46fb-93de-d10660a46b70)
　　没办法，只能手动从horizon释放掉浮动IP了。登录UserA，手动释放掉浮动IP10.100.0.3，现在就可以正常删除了。
　　现在删除Ext-Net2就没问题了。

　　总结：用admin删除网络时注意，admin看不到租户分配的浮动IP，所以得用租户登录释放掉浮动IP。
　　目标：删除租户的网络

　　路由接着外网和私网的子网。
　　所以先删路由上的网关



root@sc-ctrl01:~# neutron router-gateway-clear TenantB-Router

　　再删路由上的接口，删除某个路由的某个接口



root@sc-ctrl01:~# neutron router-interface-delete  TenantB-Router TenantB-Net-SubNet
Removed interface from router TenantB-Router.
root@sc-ctrl01:~#
　　port是关联路由和子网的。所以清掉路由上的接口，那port就没有了。



root@sc-ctrl01:~# neutron router-delete TenantB-Router
Deleted router: TenantB-Router
　　接着删子网

Deleted subnet: TenantB-Net-SubNet
　　最后网络就可以删掉了
