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
inet6 addr: fe80::221:5aff:fe48:dabe/64 Scope:Link
UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1

RX bytes:12963 (12.6 KiB) TX bytes:9144 (8.9 KiB) bond1 Link encap:Ethernet
HWaddr 00:1F:29:6D:7D:08
inet addr:192.168.44.41 Bcast:192.168.44.255 Mask:255.255.255.0
inet6 addr: fe80::21f:29ff:fe6d:7d08/64 Scope:Link

TX packets:223 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:4612 (4.5 KiB) TX bytes:31746 (31.0 KiB) 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. What may cause this ? I don’t find any helpful
information in /var/log/messages, what may I check to investigate ? I’ve not setted any fence device, as I have
configured GFS resource internally to the service ( GFS partition is mounted
only from the server running the service ): is this a wrong design ? Has anyone already setup this kind of service on a
Centos cluster ? Many thanks in advance for any hints. Fabio |
