21.3. 重新调度节点并清理网络服务

流程

1. 以 stack 用户身份登录 undercloud。

2. 查找 overcloud 凭证文件：

   示例

   $ source ~/overcloudrc

3. 验证 RHOSP 网络服务进程是否存在，并且标记为 overcloud-networker-1 的 out-of-service (xxx)。

   $ openstack network agent list -c ID -c Binary -c Host -c Alive  | grep overcloud-networker-1

   ML2/OVN 的输出示例

   +--------------------------------------+-----------------------+-------+-------------------------------+
   | ID                                   | Host                  | Alive | Binary                        |
   +--------------------------------------+-----------------------+-------+-------------------------------+
   | 26316f47-4a30-4baf-ba00-d33c9a9e0844 | overcloud-networker-1 | xxx   | ovn-controller                |
   +--------------------------------------+-----------------------+-------+-------------------------------+

   ML2/OVS 的输出示例

   +--------------------------------------+-----------------------+-------+------------------------+
   | ID                                   | Host                  | Alive | Binary                 |
   +--------------------------------------+-----------------------+-------+------------------------+
   | 8377-66d75323e466c-b838-1149e10441ee | overcloud-networker-1 | xxx   | neutron-metadata-agent |
   | b55d-797668c336707-a2cf-cba875eeda21 | overcloud-networker-1 | xxx   | neutron-l3-agent       |
   | 9dcb-00a9e32ecde42-9458-01cfa9742862 | overcloud-networker-1 | xxx   | neutron-ovs-agent      |
   | be83-e4d9329846540-9ae6-1540947b2ffd | overcloud-networker-1 | xxx   | neutron-dhcp-agent     |
   +--------------------------------------+-----------------------+-------+------------------------+

4. 捕获为 overcloud-networker-1 注册的代理的 UUID。

   $ AGENT_UUIDS=$(openstack network agent list -c ID -c Host -c Alive -c Binary -f value | grep overcloud-networker-1 | cut -d\  -f1)

5. 从数据库中删除任何剩余的 overcloud-networker-1 代理。

   $ for agent in $AGENT_UUIDS; do neutron agent-delete $agent ; done

   输出示例

   Deleted agent(s): 26316f47-4a30-4baf-ba00-d33c9a9e0844
