OpenStack neutron刪除網路裝置出錯解決辦法

目標：要刪除外網Ext-Net2

直接刪網路也會出錯：因為有一個或多個埠在使用該網路

通過horizon檢視，發現該浮動IP，沒有被分配，但是用命令卻查不到

[email protected]:~# 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)

沒辦法，只能手動從horizon釋放掉浮動IP了。登入UserA，手動釋放掉浮動IP10.100.0.3，現在就可以正常刪除了。

現在刪除Ext-Net2就沒問題了。

總結：用admin刪除網路時注意，admin看不到租戶分配的浮動IP，所以得用租戶登入釋放掉浮動IP。

路由接著外網和私網的子網。

所以先刪路由上的閘道器

[email protected]:~# neutron router-gateway-clear TenantB-Router
Removed gateway from router TenantB-Router

再刪路由上的介面，刪除某個路由的某個介面

[email protected]:~# neutron router-interface-delete  TenantB-Router TenantB-Net-SubNet
Removed interface from router TenantB-Router.
[email protected]:~#

port是關聯路由和子網的。所以清掉路由上的介面，那port就沒有了。

[email protected]:~# neutron router-delete TenantB-Router
Deleted router: TenantB-Router

接著刪子網

[email protected]:~# neutron subnet-delete TenantB-Net-SubNet
Deleted subnet: TenantB-Net-SubNet

最後網路就可以刪掉了

[email protected]:~# neutron net-delete TenantB-Net
Deleted network: TenantB-Net
