[clue] EL-6 Ethernet port bonding

[Christopher Cross]

I cannot for the life of me get port bonding to work in EL-6. Here is what
the ifcfg files and modprobe.d/bonding.conf look like

# cat ifcfg-bond0
> DEVICEE="bond0"
> ONBOOT="yes"
> BOOTPROTO="none"
> IPADDR="172.16.200.11"
> IPV6INIT="no"
> NETMASK="255.255.255.0"
> USERCTL=no
> BONDING_OPTS="mode=4 miimon=100"


# cat ifcfg-p2p1
> DEVICE=p2p1
> BOOTPROTO=”none”
> HWADDR=xxxxxxxx
> NM_CONTROLLED=”no”
> ONBOOT=”yes”
> TYPE=”Ethernet”
> UUID=xxxxxxx
> MASTER=bond0
> SLAVE=yes
> USERCTL=no


# cat ifcfg-p2p2
> DEVICE=p2p2
> BOOTPROTO=”none”
> HWADDR=xxxxxxxx
> NM_CONTROLLED=”no”
> ONBOOT=”yes”
> TYPE=”Ethernet”
> UUID=xxxxxxx
> MASTER=bond0
> SLAVE=yes
> USERCTL=no


# cat /etc/modprobe.d/bond.conf
> alias bond0 bonding


# lsmod | grep bonding
> bonding               127363  0
> 8021q                  25317  1 bonding
> ipv6                  321454  86
> bonding,ip6t_REJECT,nf_conntrack_ipv6,nf_defrag_ipv6


I run service network restart and get. I should note that the bonding
module is not loaded at boot.

# service network restart

Shutting down loopback interface:                          [  OK  ]
> Bringing up loopback interface:                            [  OK  ]
> Bringing up interface bond0:  Device does not seem to be present, delaying

Now I can create the bond manually and it works.

# modprobe bonding mode=4 miimon=100
> # ifconfig bond0 172.16.200.11/24
> # ifenslave bond0 p2p1
> # ifenslave bond0 p2p2
> # ping -c 3 172.16.200.13
> PING 172.16.200.13 (172.16.200.13) 56(84) bytes of data.

Not sure what I am doing wrong but I need some help.
