Dotaz: Fedora 18 - bond 802.3ad - network problem

[Punny]

Zdravim,

Jako vzdy bych Vas rad pozadal o konzultaci :)
Pravdepodobne nastala nekde chyba. Jedna se o komunikaci mezi servery, ktere jsou nastaveny pro link agregaci.
Projeveni chyby:
Server 1: IP 172.24.39.30
Server 2: IP 172.24.39.31
Server 3: IP 172.24.39.29

Servery 1 a 2 jsou pripojeny pomoci link agregace 802.3ad (4 x 1Gb/s).
Vsechny servery dokazi komunikovat s branou 172.24.39.1
Vsechny servery dokazi komunikovat se svetem ven a prijimaji komunikaci (lze se pripojit pres ssh z jine site).
Problem nastava pri komunikaci ve stejne siti a to, ze server 1 a 2 mohou komunikovat spolu, ale s nikym jinym ve stejne siti.
Server 3 muze komunikovat ve stejne siti pouze s adresy, ktere nejsou pripojeny v modu 802.3ad (iLO, iDrac, atd...)

Nastaveni site je:
IP: 172.24.39.29 – 250
Mask: 255.255.255.0
Gateway: 172.24.39.1
Network: 172.24.39.0
Broadcast: 172.24.39.255

Firewall je prozatim vsude vypnut.

Nastaveni ifcfg-emX

ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none
NM_CONTROLLED=no

Nastaveni ifcfg-bond0 pro Server 2

DEVICE=bond0
USERCTL=no
ONBOOT=yes
BROADCAST=172.24.39.255
NETWORK=172.24.39.0
NETMASK=255.255.255.0

Nenapada Vas, kde by mohla byt chyba?

Vsem dekuji za napady :)

Našel jsem postup, jak jsem to kdysi konfiguroval. Snad ti to pomúže

# vi /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
IPADDR=192.168.1.20
NETWORK=192.168.1.0
NETMASK=255.255.255.0
BROADCAST=192.168.1.255
GATEWAY=192.168.1.1
USERCTL=no
BOOTPROTO=none
ONBOOT=yes

# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none
# doporuceno RH ORACLE
ETHTOOL_OPTS="speed 1000 duplex full autoneg off"

# vi /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none

# doporuceno
ETHTOOL_OPTS="speed 1000 duplex full autoneg off"

# vi /etc/modprobe.conf
alias bond0 bonding
options bond0 mode=balance-alb miimon=100

#Zde je možno i specifikovat podel RedHatu pro Oracle

install bond0 /sbin/modprobe bnx2; /sbin/modprobe e1000; \
/sbin/modprobe -i bonding -o bond0 mode=balance-alb \
arp_ip_target=192.168.1.20 arp_interval=200
BONDING_OPTS="mode=active-backup arp_interval=60 arp_ip_target=192.168.1.254"
Kde arp_ip_target by mělo být GATEWAY

# restart serveru

#modprobe bonding; service network restart
