when starting the cluster i get just warnings, but updating the config and
using cman_tool version -r cman doesn't reload it, so i am forced to fix my
errors :)

The cluster is not a production one, so it is OK and am looking for the
correct end result. My question was actually 'Is encription key valid/used
only from <totem> section or in <cman> too as described in cluster.rng file'.

Multicast and keyfile are present in both <cman> and <totem> ... i guess
<totem> is the preferred one for future compatibility?
