I re-created this cluster tests in two cases: using only 5.2 media, and using rhn update.

-In case of using only the 5.2 media, I can create the cluster just fine with ricci-0.12.0-7.el5 and luci-0.12.0-7.el5.

In the other case that I rhn_register the system with RHN and download ricci-0.12.1-7.el5/luci-0.12.1-7.el5 from RHN, I get the error as already mentioned.

All systems have the same configurations : they are snapshot systems from one source.

I set up new hosts using RHEL5.3 to try cluster with RH.
- on cluster nodes, I install and start ricci
- on my admin system, I install luci.
- I turn off iptables on all systems

In Luci web interface, I create a new cluster Ex1 with one node and get the following error:

An error occured when trying to contact any of the nodes in the Ex1 cluster.

tcpdump running on cluster nodes shows packets exchanged between them and luci host over port 11111.

I thought this error is simple, but after trying it for more than an hour, I still not be able to figure the problem.

Any advice is greatly appreciated.

Thanks,
Vu
