[Pacemaker] No communication between nodes (setup problem)

[and k]

Hi,

It seem to be problem with network traffic.

Have you tried to sniff network traffic to be sure that udp traffic reaches
from one node to another ??

Try on server1:

tcpdump -i interface -p udp -s 192.168.100.112

on server2:

tcpdump -i interface -p udp -s 192.168.100.111


if there will be no packet traffic, that means you have some network issue.

BTW: Is SELinux enabled on nodes ??

Andrew
