Hi all,
I'm trying to setup a cluster of 2 machines with Centos 5.2 to host a postfix+spamassassin+clamav+mailscanner service. Below cluster software versions
rgmanager.i386 2.0.38-2.el5_2.1 installed
cman.i386 2.0.84-2.el5_2.2 installed
Every machine (hp blade server ) has 4 interfaces, bounded in this way:
Eth0, eth1 -> bond0 -> connection for public service ( 10.0.181.x )
Eth2,eth3 -> bond1 -> connection for intra-cluster communication ( 192.168.44.x )
bond0 Link encap:Ethernet HWaddr 00:21:5A:48:DA:BE
inet addr:10.0.181.41 Bcast:10.0.181.255 Mask:255.255.255.0

Then I've created a new Mail service with these local resources:
Ip address 10.0.181.3
Script /etc/rc.d/init.d/MailScanner
GFS file system on a SAN
Service start, but the problem is that, when I stop the service, external ip address is removed from bond0.
Hi Fabio,
Could you please attach the following files:
/etc/sysconfig/network-scripts/ifcfg-bond0 /etc/sysconfig/network-scripts/ifcfg-bond1 /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1 /etc/sysconfig/network-scripts/ifcfg-eth2 /etc/sysconfig/network-scripts/ifcfg-eth3 /etc/cluster/cluster.conf
And "external ip address is removed from bond0." - I assume here external IP is 10.0.181.41, right?

Hi Gowrishankar,
requested files attached; you well understand, I mean ip 10.0.181.41 disappear ( below the output from ifconfig after I tried to stop the service)
bond0 Link encap:Ethernet HWaddr 00:21:5A:48:DA:BE inet6 addr: fe80::221:5aff:fe48:dabe/64 Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1 RX packets:52958 errors:0 dropped:0 overruns:0 frame:0 TX packets:7844 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:4915061 (4.6 MiB) TX bytes:4936239 (4.7 MiB)
