Fresh rhel 5.4 installation on 2 nodes, clustering and cluster storage
groups, Oracle Rac installed on both systems.
When we try to configure the cluster (cluster suite i mean) using Luci
web interface, just after pressing the "Create Cluster" button, the
operation fails and in /var/log/messages we find these strings:

[...]

accept Library connection: (null) - prior to this log entry, openais
logger dropped '5' messages because of overflow.
Nov 26 10:33:39 sdbsap01 openais[16218]: [MAIN ] ERROR: Could not

and

service cman status return

[root at sdbsap01 ~]# service cman start
Starting cluster:

Starting ccsd... done
Starting cman... failed

[FAILED]
[root at sdbsap01 ~]#


and this is our cluster.conf file:

[root at sdbsap01 ~]# cat /etc/cluster/cluster.conf
<?xml version="1.0"?>
<cluster alias="cludbsap01" config_version="1" name="cludbsap01">
<fence_daemon post_fail_delay="0" post_join_delay="3"/>
<clusternodes>
<clusternode name="sdbsap01-priv" nodeid="1" votes="1"/>
<clusternode name="sdbsap02-priv" nodeid="2" votes="1"/>
</clusternodes>
<cman expected_votes="1" two_node="1"/>
<fencedevices/>
<rm/>
</cluster>


Using tcpdump multicast seems to allowed between the nodes

We are already tried to remove all the packages (yum groupremove
"Clustering" "Cluster Storage"), the /etc/cluster and /var/lib/luci
and /var/lib/ricci directories, and then reinstalling the cluster
suite, but we still have this problem.

Any suggestions?

Marco
