Yes but if cluster communications are still going on I find it harsh to
self-fence.  I get what you mean but at least I think this should be up
to the administrator; a configurable parameter (and that's what they've
done in SUSE with the -P option).

Yes, I read about that one but I believe that if my SBD disk fails , the
rest might fail as well since they all come from the same SAN & same

What I'm debating in my head is whether to use a small partition within
one of the production LUNs (LUNs shared with the other node for
application data) or if I should request a separate small LUN just for SBD.
