1.查看异常member的信息，获取租户id和ip，以及负载均衡池的id
[root@node-1 ~](controller)# neutron lb-member-show 8371cd6d-1aa0-41c8-b65a-cf6da2706c72
+--------------------+--------------------------------------+
| Field | Value |

8.登录到pool所在节点，根据pool_id找到对应的命名空间，然后telnet 对应端口，发现不通
[root@node-1 ~](controller)# ip netns | grep 55122608-20d9-467d-9fb7-f9d312b9ea68
qlbaas-55122608-20d9-467d-9fb7-f9d312b9ea68
[root@node-1 ~](controller)# ip netns exec qlbaas-55122608-20d9-467d-9fb7-f9d312b9ea68 telnet 192.168.10.30 80
Trying 192.168.10.30...
telnet: connect to address 192.168.10.30: Connection refused
