system-config-cluster error

[Fabrizio Lippolis]

I am configuring a cluster of 2 HP machines and I just installed Fedora 
Core 4 on both machines with the proper services to run a cluster and 
share resources. I managed to share a disk array as a single partition 
with both machine by the Global File System.

To further configure the cluster I installed the system-config-cluster 
RPM package as suggested by the documentation which anyway is not part 
of the Fedora Core 4 CDs. I found it on rpmfind and installed with an 
rpm -i command. I can start the application and make changes but if I 
try to save them I get the following trace.

[root at AICLSRV01 cluster]# Traceback (most recent call last):
   File "/usr/sbin/system-config-cluster", line 435, in propagate
     if self.model_builder.exportModel(CLUSTER_CONF_PATH) == True:
   File "/usr/share/system-config-cluster/ModelBuilder.py", line 361, in 
exportModel
     if self.perform_final_check() == False: # failed
   File "/usr/share/system-config-cluster/ModelBuilder.py", line 780, in 
perform_final_check
     self.check_two_node()
   File "/usr/share/system-config-cluster/ModelBuilder.py", line 806, in 
check_two_node
     self.CMAN_ptr.addAttribute('two_node', '1')
AttributeError: 'NoneType' object has no attribute 'addAttribute'

Anybody can help me to make it work? Or perhaps should I get a different 
package? The one I downloaded is 
system-config-cluster-1.0.24-1.0.noarch.rpm. Thanks in advance.
