起搏器无法启动drbd资源

Question

下面是配置显示的crm

[root@node1 /]# crm configure show

在node1之前: crm资源启动drbd_res

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

Node1后: crm资源启动drbd_res

它把我的node2下载了，我不能让node2回到次要位置.

[root@node2 /]# service drbd status

我出什么差错了吗？

Answer 1

有几件事你可以试试。首先，确保节点能够“看到”对方。

node1:~# ping node2 && node2:~# ping node1

还有一件事你不应该忘记，那就是心脏起搏器必须控制DRBD。起搏器启动时DRBD不能运行。如果是的话，你会发现所有奇怪的事情都会发生。除此之外，您还可以发布您的drbd配置。

希望这在某种程度上有帮助。随时通知我们，我自己是一个狂热的DRBD用户，所以我有兴趣知道解决方案。

Answer 2

有更多的日志可能会有帮助，但首先看一看，对于主/从资源，您有一个“目标角色=已启动”，这对我来说似乎很奇怪。试着移除它。
