suse11sp2搭建ha疑问

小弟刚看到suse的ha的搭建。自己搭建了个环境，node01（主）和node02。

在node01上通过yast2 cluster的图形界面配置好node01（启动了openais；生成了authkey、key_hagroup两个文件），

将authkey、key_hagroup、csync2.cfg、corosync.conf这四个文件拷贝到了node02。

node01和node02未做ssh信任。

之后在node01上执行“csync2 -xv”，出现以下报错：

node01:/etc/corosync # csync2 -xv

node01和node02的能够相互ping通，网络没什么问题。hosts文件也定义过。

这个是什么原因啊？谢谢！
