我设置了 2 台机器，安装了 Pacemaker 和 Corosync。其中运行着 PostgreSQL 主/从集。主服务器有一个资源组，该资源组有一个虚拟 IP 和两个应该在主服务器上运行的附加服务。如果通过关闭数据库主服务器触发故障转移，这会将组中的所有服务迁移到另一个节点，这正是我期望和想要它做的事情。
但是，当我终止这些附加服务时，它们只会被标记为失败，仅此而已。由于我只希望在数据库发生故障时进行迁移，所以这实际上没问题。但是，我希望 Pacemaker 在这些服务发生故障时重新启动它们，而不仅仅是将它们标记为失败。
我的期望是，当我将 on-fail=restart 标志添加到这些服务的监视操作时，它就会做到这一点，但事实并非如此。
该组如下所示：
Group: master-group

Operations: start interval=0s timeout=20s (VirtualIP-start-interval-0s)

Resource: additional-resource1 (class=ocf provider=heartbeat type=additional-resource1)
Operations: stop interval=0s timeout=20s (additional-resource1-stop-interval-0s)
monitor interval=60s timeout=20s (additional-resource1-monitor-interval-60s)

monitor interval=60s on-fail=restart timeout=0s (additional-resource2-monitor-interval-60s)

有人能解释一下如何实现这一点吗？
