Hi Zoran,
Glad that you got it working.
Using only one seed should be possible, but only one can have itself as
seed node.
E.g.
node1 may have seed-nodes=[node1]
node2 may have seed-nodes=[node1]
node3 may have seed-nodes=[node1]
then, later on, when the cluster is running, you could use any other node
as seed
node100 may have seed-nodes=[node3]
However, using only one seed node is a single point of failure, so I don't
see why you would use that.
