10.3. 修改仲裁选项（红帽企业 Linux 7.3 及更新的版本）
从 Red Hat Enterprise Linux 7.3 开始，您可以使用 pcs quorum update 命令修改集群的常规仲裁选项。您可以在正在运行的系统上修改 quorum.two_node 和 quorum.expected_votes 选项。对于所有其他仲裁选项，执行此命令要求停止群集。有关仲裁选项的详情，请查看 votequorum(5)man page。
pcs quorum update 命令的格式如下。
pcs quorum update [auto_tie_breaker=[0|1]] [last_man_standing=[0|1]] [last_man_standing_window=[time-in-ms] [wait_for_all=[0|1]]
以下一系列命令修改
wait_for_all 仲裁选项并显示 选项的更新状态：请注意，系统不允许在集群运行时执行这个命令。
