[Linux-cluster] Cman doesn't realize the failed node

[Hakan VELIOGLU]

Hi,

I am testing and trying to understand the cluster environment. I ve  
built a two node cluster system without any service (Red Hat EL 5.2  
x64). I run the cman and rgmanager services succesfully and then  
poweroff one node suddenly. After thsi I excpect that the other node  
realize this failure and take up all the resources however running  
node doesn't realize this failure. I use "cman_tool nodes" and  
"clustat" commands and they say the failed node is active and online.  
What am i missing? Why cman doesn't realize the failure?

[root at cl1 ~]# cat /etc/cluster/cluster.conf

When the node gows down, the TOTEM repeastedly logs messages like this.
