[edit] Cluster nodes configurations
Actually the ip of the 2nd interface on each cluster node is configured automatically at start-up by adding +128 to the boot ip address.
This is done by the script /etc/init.d/network present in the rootOS (i.e. not in the snapshot).
In the script there is this section:
### eth autoconfig ###
# This part of the script read the eth0 ip address and make
# an additional ip to assign to eth1, adding 128 to the last ip octet
# Author: Gianluca
# Date: 17/02/2009
sysconf_path=/etc/sysconfig/network-scripts
interface2=eth1
interface21=eth1.92
# Here we assume that the ip on eth0 is previusly assigned by dhcp
ip=`/sbin/ifconfig | awk '/HWaddr|Bcast/ {split($0,lines,"\n"); print lines[1];}'|sed -e '$!N;s/\n/ /' -e 's/addr://g' |awk '{print $7}'|grep 192.168`
n1=`echo $ip|cut -d '.' -f 1`
n2=`echo $ip|cut -d '.' -f 2`
n3=`echo $ip|cut -d '.' -f 3`
n4=`echo $ip|cut -d '.' -f 4`
# Add 128 to the last octet
let c4=$n4+128;
# The new ip to assign to eth1.92 interface
ip2=$n1.$n2.$n3.$c4
# Write the configuration in the sysconfig directory
# Write the configuration in the sysconfig directory for eth1.2
echo "DEVICE=$interface21" > $sysconf_path/ifcfg-$interface21
echo "VLAN=yes" >> $sysconf_path/ifcfg-$interface21
echo "BOOTPROTO=none" >> $sysconf_path/ifcfg-$interface21
echo "BROADCAST=192.168.191.255" >> $sysconf_path/ifcfg-$interface21
echo "IPADDR=$ip2" >> $sysconf_path/ifcfg-$interface21
echo "NETMASK=255.255.192.0" >> $sysconf_path/ifcfg-$interface21
echo "NETWORK=192.168.128.0" >> $sysconf_path/ifcfg-$interface21
echo "ONBOOT=yes" >> $sysconf_path/ifcfg-$interface21
echo "TYPE=Ethernet" >> $sysconf_path/ifcfg-$interface21
# Write the configuration in the sysconfig directory for eth1
echo "DEVICE=$interface2" > $sysconf_path/ifcfg-$interface2
echo "BOOTPROTO=none" >> $sysconf_path/ifcfg-$interface2
echo "IPADDR=0.0.0.0" >> $sysconf_path/ifcfg-$interface2
echo "ONBOOT=yes" >> $sysconf_path/ifcfg-$interface2
echo "TYPE=Ethernet" >> $sysconf_path/ifcfg-$interface2
### End eth autoconfig ###
Moreover, in the files.custom of snapshots it is necessary add the line /etc/init.d/network-scripts/ifcg-eth1.92
