红帽全球峰会72.33. 服务器重新定义大小
将服务器扩展为新类别。通过创建新服务器并将原始磁盘的内容复制到新磁盘来实现大小操作。用户还有两步过程：首先执行调整大小，第二个步骤是确认（验证）成功并释放旧服务器，或者声明恢复以释放新服务器并重新启动旧服务器。
使用方法：
openstack server resize [-h] [--flavor <flavor> | --confirm | --revert]
[--wait]
<server>
openstack server resize [-h] [--flavor <flavor> | --confirm | --revert]
[--wait]
<server>| 值 | 概述 |
|---|---|
| <server> | 服务器（名称或 id） |
| 值 | 概述 |
|---|---|
| -h, --help | 显示帮助信息并退出 |
| --flavor <flavor> | 将 server 的大小调整为指定类别 |
| --confirm | 确认服务器重新定义大小完成 |
| --revert | 在调整大小前恢复服务器状态 |
| --wait | 等待调整大小完成 |
