Found my problem
When running cman_tool status I saw that each node only saw 1 node.
I have 2 pairs of network on each machine (heartbeat network 1gbit multicast enabled/application network 10Gbit) with their own host mapping in /etc/hosts
I used the the non-heartbeat hostname to add nodes into cluster via luci which caused issues.
Removed luci & /var/lib/luci on nodes, as well as cat /dev/null /etc/cluster/cluster.conf
Reinstalled luci, created cluster, added 2 nodes with correct hostnames, problem solved.
Could anyone point me to a good guide for using cluster lvm ?
Thx

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
Hard to say what issue is based on this without checking fully logs, can you please open case via Red Hat customer portal https://access.redhat.com ( I assume you have valid subscription ) so we can take deeper look into this problem.
Thank you in advance,
