Thank you for the tip. It doesn't explain my problem, but it help me: I
can reach all the 3 node with my curl request, but sometime, one not
respond. And as he doesn't answer I don't know who don't answer :-) But
with the clone-node-max at 3, I can play to move my resource, and see that
problem happen when the resource is on one specific node. Not the one I
want remove.

So 2 nodes works well, and one node sometime don't answer.
I know that this node isn't on the same switch that the first two, there
is another switch between, (3 switch interconnected), can the multicast
arp lost in the way ?

If not, this is a firewall / systctl difference between hosts ...
