Rene,
Rene Hellmann napsal(a):
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
Do you really have mask /32? Because such setup is called point-to-point
and it's little special.
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.

As you can see a port 5405 will be opened. But only listening on 127.0.0.1.
Anyway, for point to point just set bindnet to actual IP address
(because you basically don't have network address or more correctly, ip
is network address). So just set:
bindnetaddr: A.A.A.A
and on second server
bindnetaddr: B.B.B.B
but keep in mind, that your setup seems to be little incorrect (if you
didn't setup router / routes correctly) and peer on A.A.A.A should be
B.B.B.B and reverse for B.B.B.B
Btw, I disabled iptables, firewall and selinux extensions.
There is no specific route.
Can somebody give me a hint ?
