[Pacemaker] Pacemaker on CentOS 5.6 & CentOS 6.0

[sdr(friedrich reichhart)]

Hi all!

I'm working in a cluster with CentOS 5 & 6
Storage01 - Centos5
Sotrage02 - Centos5
KVM02 - Centos5

This part works fine.

KVM04 - Centos6

[root at kvm04 ~]# /etc/init.d/corosync start && /etc/init.d/pacemaker start
Starting Corosync Cluster Engine (corosync):               [  OK  ]
Starting Pacemaker Cluster Manager:                        [  OK  ]

Both "clusters" see the other node / nodes, meaning storage01,02 + kvm02 
sees node kvm02 and node kvm02 sees all other nodes.

[root at kvm04 ~]# crm_mon -1

Online: [ kvm04.sdr.at ]
OFFLINE: [ kvm02.sdr.at inet-storage01.sdr.at inet-storage02.sdr.at ]

The OFFLINE nodes were not entried manually, pacemaker found them as 
well as "on the other side".

I'm using standard repositories + EPEL + Clusterlabs.

What may be wrong?
Config files, auth-file, service.d might be configured ok.

Thanks for help,
Fritz.
