25.2. 修改仲裁选项

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_nodequorum.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。

[root@node1:~]# pcs quorum update wait_for_all=1
