Hi Jacob,
Have I to create a /etc/cluster.conf on the 2nd node and I put the 1st node
as preferred node?
Thanks a lot

You need to start the clustering services on the 2nd node so it can join
the cluster. Otherwise it wont be able to access the disk protected by
the cluster services on node1. the cluster service controllers when and
whether the shared disk resources get mounted by a cluster host.
Thanks, jacob
