Red Hat Enterprise Linux 5.x/6.x bonding ayarlamak

2009 yılındaki çalışma notumu biraz güncelleyerek burada da olsun istedim.

"RHEL 5.3 uzerinde bonding (Bonding Mode: fault-tolerance (active-backup) )" - Remzi AKYUZ - (2009-08-27 06:01:00)

1. /etc/modprobe.d/bonding.conf dosyasına

alias bond0 bonding
options bonding mode=1 miimon=100

satırı ilave edilir.

2. /etc/sysconfig/network-scripts/ifcfg-bond0 dosyası oluşturulur ve içerisine
DEVICE=bond0
TYPE=bond
ONBOOT=yes
HOTPLUG=no
BOOTPROTO=none
USERCTL=no
NM_CONTROLLED=no
BONDING_OPTS="mode=1 miimon=100"
BROADCAST=192.168.1.255
IPADDR=192.168.1.100
NETMASK=255.255.255.0
NETWORK=192.168.1.0


satırı ilave edilir.

3. bondingde kullanılacak ethernetler ayarlanır. eth1 ve eth2 yi kullanacağız

/etc/sysconfig/network-scripts/ifcfg-eth1 icerisinde aşağıdaki satırlar olmalı.

DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no
HOTPLUG=no

/etc/sysconfig/network-scripts/ifcfg-eth2 içerisinde aşağıdaki satırlar

DEVICE=eth2
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no
HOTPLUG=no

4. Kontrol için
[root@localhost ~]# cat /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: v3.2.4 (January 28, 2008)

Bonding Mode: fault-tolerance (active-backup)
Primary Slave: None
Currently Active Slave: eth2
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0

Slave Interface: eth1
MII Status: down
Link Failure Count: 0
Permanent HW addr: 08:00:27:5c:33:61

Slave Interface: eth2
MII Status: up
Link Failure Count: 0
Permanent HW addr: 08:00:27:a5:24:6a

Son olarakta fiziksel olarak(kablolar sökülüp takılarak test edilir.
Loglardada aşağıdakileri görebiliriz.
