我有 2 个 VM 节点集群。Postgres 通常在主从复制模式下工作 - 已测试。
添加 pgsql 作为 pcs 资源时出现错误：来自日志文件
care1 pgsql(pgsql)[30160]: ERROR: Replication(rep_mode=async or sync) requires Master/Slave configuration.
我已执行的命令：

如果我做错了什么，请指教

该错误中的问题相当明显：
ERROR: Replication(rep_mode=async or sync) requires Master/Slave configuration.
您需要为 rpgsql 原语配置 MS（主/从）类型资源。请参阅文档中的第二个示例，以将其应用于已创建的资源。https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Configuring_the_Red_Hat_High_Availability_Add-On_with_Pacemaker/s1-multistateresource-HAAR.html
为方便起见，此处粘贴示例：
pcs resource master master/slave_name resource_id|group_name [master_options]
