RE: [Linux-cluster] GFS 6.0 node without quorum tries to fence



Agreed.  But I though that the quorum concept was there to protect
against a netsplit causing independent clusters to form.  If I'm a node
and I can't contact enough peers to gain quorum, then I can't be a part
of the cluster.  If I'm not part of the cluster, then I shouldn't be
fencing other nodes.

Am I missing something?

Think of the world as the nodes see it, not as you see it.  You cannot
tell if it is a netsplit or truely nodes dieing.  It looks the same.
