I may be wrong. I just tried luci on my 5.2 system to add a node and it 
failed. Anyway, it successful updates cluster.conf of existing nodes so 
all I did after to add new node to the cluster is :
- scp /etc/cluster/* from existing node to new node
- install the following packages : gfs2-utils gfs-utils rgmanager 
kmod-gfs2-xen kmod-gfs-xen lvm2-cluster. You may not need the *-xen-* 
packages if you are not on a domU.
- start services cman, clvmd, gfs2 and rgmanager.

After that my new node joins the cluster just fine . Then luci sees my 
new node, too.

I love luci, I hate lucy. I still not remember all the options of 
cluster services so I still have to use it. For options I remember, I 
just edit cluster.conf with vi and ccs_tool update.
