Hi Honza,
As you said I use the nodename identify by hostname (which be accessed
via IPv6) and the node also has the altname (which be IPv4 address).
Now, I configure the mcast address for both nodename and altname
manually. The CMAN and Pacemaker can start ad well. But they don't
communicate to another node.
On node0, crm_mon show node1 offline. In the same way, node one show
node0 is down. So the split brain problem occur here.
Regards,
Te
