Hello! I've two node cluster created from two xenserver guests each node located on the different dom0 node0 on dom0-0 node1 on dom0-1
for stonith I'm going use this http://code.google.com/p/fence-xenserver/ but questions probably not related to this details , it mostly theoretical so, I tried to block network connections with iptables on node0: iptables -A OUTPUT -d node1 -j REJECT iptables -A INPUT -s node1 -j REJECT and as result - all cluster resources was started on the both nodes drbd was switched to the Primary/Unknown state on both nodes too and so on ... and as far as I understood if I will have stonith enabled pacemaker kill one of the cluster node (am I right?) but how pacemaker decide which node to kill ? in my case node0 and node1 is up and running, which of them will be killed ? how pacemaker know that another node is up and it is only network issue?
