我在我在其中一台机器（LINUX1）上起service cman start,在这之前两台机器的cman都是没起的
日志刷出以下内容：

我如果在另一台机器上起cman，也会刷出相同的日志，只是 LINUX2换成了LINUX1;

两台机器cman都起来后，两台机器的情况入下：

请教各位高手，这是什么问题，如何解决？

把你的结构拓扑，以及
配置文件/etc/cluster/cluster.conf，/etc/hosts，以及/var/log/message拿来看看。

我觉得，应该是配置文件错。

1、你的cluster是用conga配置的还是system-config-cluster配置的？

检查所有的集群组件安装成功，检查关键服务是否启动成功。

2、clustat -l显示的结果是1台主机被识别，另一台主机并没有被识别，而且显示都没有被rmager管理，好似心跳解析有问题，从hosts文件可见，建议换个IP段，命名使用全称。

基本上是上面说的问题，第二台主机在启动的时候无法获得第一台主机的心跳，当然第一台主机也是一样。
日志中显示不出除自己之外其他主机加入的信息，在此情况下实际上cluster是无法quorum的。

所以：
首先你的硬件结构是怎样的？物理上必须要保证心跳信号所在的线路也就是10.31和10.33是通的，同时注意检查防火墙是否对心跳信号有影响。
另外既然是RHEL5的集群，你是在用哪个kernel？如果是xen的话，换成普通的kernel。xend会对集群网络配置有影响。

1.我是用system-config-cluster配置的;
2.两台机器的10.31,10.33的地址是通的，相互能ping通，两台机器的防火墙都已禁用;
3.我见clustat -l看到的信息不对，因此没有起rgmanager;
4.操作系统的内核应该不是xen,我用redhat的的光盘装的,没动过内核;
5.后来我用conga重新配了一遍，还是同样的问题;
6.我还遇到过这样的情况，两台机器用clustat -l看，两个节点都是online,但Local会分别的自已的节点上，也就是讲在node1上看，local就在node1,在node2上看，local就在node2。

这是正常的。至于你说的上面其他的情况，按照你讲的应该没有问题。
