多 bonding 使用不同 mode 方法

环境,

多网卡, 多 bond 设备,  需要使用不同的工作方式, 如下:

eth0  eth1  -> bond0  ->  mode 0  ( active-backup )

eth2, eth3  -> bond1  -> mode 1  (balance-rr)

参考:

[root@hh-yun-puppet-129021 kickstarts]# yum install -y kernel-doc

[root@hh-yun-puppet-129021 kickstarts]# rpm -ql kernel-doc | grep bonding.txt
/usr/share/doc/kernel-doc-2.6.32/Documentation/networking/bonding.txt

其中该文档描述

/etc/modprobe.d/bond.conf 需要具有下面的配置

<pre class="plain" name="code">alias bond0 bondingoptions bond0 -o bond0 mode=balance-rr miimon=100alias bond1 bondingoptions bond1 -o bond1 mode=balance-alb miimon=50

但上述文档只能够针对 centos 5 或之前版本,  而文档也没有更新 centos 6, 7 下的方法

而 centos 6,7 将不可以使用 -o 参数进行参数定义,  另外,  假如把配置, 参数都写入 /etc/modprobe.d/bond.conf 如

alias bond0 bondingoptions bond0 mode=balance-rr miimon=100alias bond1 bondingoptions bond1 mode=balance-alb miimon=50

看上去 bond0, bond1 可以启动,  但从内核参数显示,  上述的设备只会使用相同的工作模式,  不满足不同 bond 设备使用不同模式方法

参考:

[root@hh-yun-compute-130026 ~]# grep Mode /proc/net/bonding/bond0Bonding Mode: load balancing (round-robin)[root@hh-yun-compute-130026 ~]# grep Mode /proc/net/bonding/bond1Bonding Mode: load balancing (round-robin)

centos 6, 7 上正确配置方法:

/etc/modprobe.d/bond.conf

alias bond0 bondingalias bond1 bonding

/etc/sysconfig/network-scripts/ifcfg-bond0

BONDING_OPTS='mode=1 miimon=100'

/etc/sysconfig/network-scripts/ifcfg-bond1

BONDING_OPTS='mode=0 miimon=100'

另: 注意,  centos 7  下, 假如关闭 ipv6 模块使用,  那么 bond 模块也是无法正常使用的.

而 centos 7 已推荐使用 teamd 进行 bond 配置

teamd 与 bond 实现相同功能,  但新增不少新特性,  比较灵活,   相关信息自己看官方文旦

测试配置方法

[root@node147 network-scripts]# cat ifcfg-eth0DEVICE="eth0"DEVICETYPE=TeamPortONBOOT=yesTEAM_MASTER=team0TEAM_PORT_CONFIG='{"prio": 100}'[root@node147 network-scripts]# cat ifcfg-eth1DEVICE=eth1DEVICETYPE=TeamPortONBOOT=yesTEAM_MASTER=team0TEAM_PORT_CONFIG='{"prio": 100}'[root@node147 network-scripts]# cat ifcfg-eth2DEVICE="eth2"DEVICETYPE=TeamPortONBOOT=yesTEAM_MASTER=team1TEAM_PORT_CONFIG='{"prio": 100}'[root@node147 network-scripts]# cat ifcfg-eth3DEVICE="eth3"DEVICETYPE=TeamPortONBOOT=yesTEAM_MASTER=team1TEAM_PORT_CONFIG='{"prio": 100}'

team 配置与 mode 配置

[root@node147 network-scripts]# cat ifcfg-team0DEVICE=team0DEVICETYPE=TeamONBOOT=yesBOOTPROTO=noneIPADDR=192.168.48.147GATEWAY=192.168.48.1PREFIX=24TEAM_CONFIG='{"runner": {"name": "activebackup"}, "link_watch": {"name": "ethtool"}}'[root@node147 network-scripts]# cat ifcfg-team1DEVICE=team1DEVICETYPE=TeamONBOOT=yesBOOTPROTO=noneIPADDR=10.0.0.147PREFIX=24TEAM_CONFIG='{"runner": {"name": "loadbalance"}, "link_watch": {"name": "ethtool"}}'
