system-config-cluster corrupts IP address on Red Hat Enterprize Linux 5.4

Solution Verified - Updated -


  • system-config-cluster corrupts IP address.

  • When editing the cluster software, the cluster software had apparently written a correct IP address for a private resource. But upon saving the trailing digit of the IP address had been removed and a wrong subnet was set.

  • Created IP as a resource but in my config file it shows two different IPs, for Resource it is showing and for monitor link it is showing

  • On exiting the system-config-cluster GUI for the first time, the following traceback appeared.

          File "/usr/share/system-config-cluster/", line 235, in onTimer
          File "/usr/share/system-config-cluster/", line 209, in prep_service_tree
          treemodel.clear()      AttributeError: 'NoneType' object has no attribute 'clear'
