在node1之前：crm资源启动drbd_res

[root@node2 /]# service drbd status
drbd driver loaded OK; device status:

node1之后：crm resource start drbd_res

它导致 node2 上的 drbd 关闭，并且我无法将 node2 恢复为辅助节点......

[root@node2 /]# service drbd status
drbd driver loaded OK; device status:

我做错什么了吗？

答案1

您可以尝试以下几种方法。首先确保节点可以“看到”彼此。

节点 1：~# ping 节点 2 && 节点 2：~# ping 节点 1

您不应忘记的另一件事是 Pacemaker 必须控制 DRBD。当 Pacemaker 启动时，DRBD 不能运行。如果是这样，您将遇到各种奇怪的事情。除此之外，您可以发布您的 drbd 配置。

希望这能有所帮助。请随时告知我们，我自己就是一名狂热的 DRBD 用户，因此我很想知道解决方案。

答案2

拥有更多日志会很有帮助，但乍一看，主/从资源的“target-role=Started”似乎很奇怪。尝试将其删除。
