红帽全球峰会3.4. 更新所有 Controller 节点
将所有 Controller 节点更新至最新的 RHOSP 16.2 版本。运行 openstack overcloud update run 命令，并包含 --limit Controller 选项，以仅限对 Controller 节点的操作。control plane API 在次版本更新过程中完全可用。
重要
在解决 BZ#1872404 之前，对于基于可组合角色的节点，您必须先更新 Database 角色，然后再更新 Controller, Messaging, Compute, Ceph 和其他角色。
注意
如果您不使用默认的堆栈名称（即 overcloud ），请将堆栈名称设置为 --stack < stack_name> 选项，并将 < ;stack_name > 替换为堆栈的名称。
