[Linux-cluster] 2 node cluster questions

Hey All,



About my setup :


I created a cluster in luci with shared storage, added 2 nodes (reachable),
added 2 fence devices (idrac).


Now, I can't seem to add my fence devices to my nodes. If I click on a node
it times out in the gui.


So I checked my node logs and found in /var/log/messages ricci hangs on
/etc/init.d/clvmd status


When I run the command manually I get the PID and it hangs.



I also seem to have a split brain config :


# clustat on node 1 shows : node 1 Online,Local

                                                    Node 2 Offline


# clustat on node 2 shows : node 1 offline

                                                    Node 2 online, Local



My next step was testing if my multicast was working correctly (I suspect it
isn't). Would you guys have any recommendations besides the following redhat
multicast test link ? : 






Some info about my systems  :



.         Redhat 6.5 on 2 nodes with resilient storage & HA addon licenses

.         Mgmt. station redhat 6.5 with Luci




Thx a lot
