Hello,
the following setup is running in unicast-mode on my staging cluster.
2 x CentOS 6.2 with EPEL repo , corosync 1.4.1 and pacemaker 1.1.6 .
IP 1 :192.168.2.111 / 24
IP 2 . 192.168.2.112 / 24
-> bindnetaddr : 192.168.2.0
Now I'm trying to get this version run on my live system.
2 root server on different sub.nets
Server 1.
A.A.A.A / 32 with Bcast A.A.A.127
ip addr | grep "inet " | tail -n 1 (see 'clusters from scratcg') give me the following line
inet A.A.A.A peer A.A.A.97/32 brd A.A.A.127 scope global eth0
Server 2.
B.B.B.B / 32 with Bcast B.B.B.127
inet B.B.B.B peer B.B.B.97/32 brd B.B.B.127 scope global eth0
If I follow the script for calculating the bindnetaddr. have to bo AAAA / B.B.B.B
if I follow ip addr | grep "inet " | tail -n 1 | awk '{print $4}' | sed s/255/0/ (see 'clusters from scratch')
It has to be A.A.A.97 and B.B.B.97
I nearly tried all combinations but nothing works:
In /var/log/messages I see:
May 13 02:59:32 pgpool02 corosync[10767]: [TOTEM ] Totem is unable to form a cluster because of an operating system or network fault. The most common cause of this message is that the local firewall is configured improperly.
netstat -nlp :

As you can see a port 5405 will be opened. But only listening on 127.0.0.1.
Btw, I disabled iptables, firewall and selinux extensions.
There is no specific route.
Can somebody give me a hint ?
