9.7. 删除 overcloud 堆栈

流程

1. 以 stack 用户身份登录 undercloud 主机。

2. 查找 stackrc undercloud 凭证文件：

   $ source ~/stackrc

3. 检索堆栈中所有节点的列表及其当前状态：

   (undercloud)$ openstack baremetal node list
   +--------------------------------------+--------------+--------------------------------------+-------------+--------------------+-------------+
   | UUID                                 | Name         | Instance UUID                        | Power State | Provisioning State | Maintenance |
   +--------------------------------------+--------------+--------------------------------------+-------------+--------------------+-------------+
   | 92ae71b0-3c31-4ebb-b467-6b5f6b0caac7 | compute-0    | 059fb1a1-53ea-4060-9a47-09813de28ea1 | power on    | active             | False       |
   | 9d6f955e-3d98-4d1a-9611-468761cebabf | compute-1    | e73a4b50-9579-4fe1-bd1a-556a2c8b504f | power on    | active             | False       |
   | 8a686fc1-1381-4238-9bf3-3fb16eaec6ab | controller-0 | 6d69e48d-10b4-45dd-9776-155a9b8ad575 | power on    | active             | False       |
   | eb8083cc-5f8f-405f-9b0c-14b772ce4534 | controller-1 | 1f836ac0-a70d-4025-88a3-bbe0583b4b8e | power on    | active             | False       |
   | a6750f1f-8901-41d6-b9f1-f5d6a10a76c7 | controller-2 | e2edd028-cea6-4a98-955e-5c392d91ed46 | power on    | active             | False       |
   +--------------------------------------+--------------+--------------------------------------+-------------+--------------------+-------------+

4. 删除 overcloud 堆栈并取消置备节点和网络：

   (undercloud)$ openstack overcloud delete -b <node_definition_file> \
    --networks-file <networks_definition_file> --network-ports <stack>

   Copy to Clipboard Toggle word wrap
   • 将 <node_definition_file > 替换为节点定义文件的名称，如 overcloud-baremetal-deploy.yaml。
   • 将 <networks_definition_file > 替换为网络定义文件的名称，如 network_data_v2.yaml。
   • 将 &lt;stack> 替换为您要删除的堆栈的名称。如果未指定，则默认堆栈为 overcloud。

5. 确认要删除 overcloud：

   Are you sure you want to delete this overcloud [y/N]?

   Copy to Clipboard Toggle word wrap
6. 等待 overcloud 删除，以及节点和网络取消置备。

7. 确认裸机节点已取消置备：

   (undercloud) [stack@undercloud-0 ~]$ openstack baremetal node list
   +--------------------------------------+--------------+---------------+-------------+--------------------+-------------+
   | UUID                                 | Name         | Instance UUID | Power State | Provisioning State | Maintenance |
   +--------------------------------------+--------------+---------------+-------------+--------------------+-------------+
   | 92ae71b0-3c31-4ebb-b467-6b5f6b0caac7 | compute-0    | None          | power off   | available          | False       |
   | 9d6f955e-3d98-4d1a-9611-468761cebabf | compute-1    | None          | power off   | available          | False       |
   | 8a686fc1-1381-4238-9bf3-3fb16eaec6ab | controller-0 | None          | power off   | available          | False       |
   | eb8083cc-5f8f-405f-9b0c-14b772ce4534 | controller-1 | None          | power off   | available          | False       |
   | a6750f1f-8901-41d6-b9f1-f5d6a10a76c7 | controller-2 | None          | power off   | available          | False       |
   +--------------------------------------+--------------+---------------+-------------+--------------------+-------------+

   Copy to Clipboard Toggle word wrap

8. 删除堆栈目录：

   $ rm -rf ~/overcloud-deploy/<stack>
   $ rm -rf ~/config-download/<stack>

   Copy to Clipboard Toggle word wrap
   注意

   如果使用 openstack overcloud deploy 命令部署 overcloud 时使用了 --output-dir 和 --working-dir 选项，则堆栈的目录路径可能与默认值不同。
