服务器重启后,bond0
由于它的一个从属以太网(eth2
)没有链接而无法启动,我必须手动设置它:
ip link set dev eth2 up
服务器与 LAN 有一个绑定(带有 KVM 桥接器),drbd 与另一台服务器有另一个绑定:
kvm + lan drbd

两个服务器都运行 Debian Wheezy,如下所示/etc/network/interfaces
:
# The loopback network interface
auto lo
iface lo inet loopback
# to the switch
auto bond0
iface bond0 inet manual
slaves eth0 eth2

slaves eth1 eth3
bond-mode balance-rr

bond-updelay 200
另一台服务器启动正确,两者之间的唯一区别interfaces
在于声明static
manual
bond0
iface bond0 inet static
我怎样才能防止这种情况再次发生?
添加ip link set
接口是个好主意吗?
auto bond0
iface bond0 inet manual
pre-up ip link set eth0 up
pre-up ip link set eth2 up
(...)
static
和之间有什么区别manual
?或者更好的是,我在哪里可以找到接口文件的完整文档?(man interfaces
没有提到绑定、桥接、无线..选项)
答案1
只需简单添加:
auto eth0
iface eth0 inet manual
up ip link set eth0 up
down ip link set eth0 down
auto eth1
iface eth1 inet manual
up ip link set eth1 up
down ip link set eth1 down
auto eth2
iface eth2 inet manual
up ip link set eth2 up
down ip link set eth2 down
auto eth3
iface eth3 inet manual
up ip link set eth3 up
down ip link set eth3 down
static
和之间的区别manual
在于静态由参数配置(如地址、网络掩码、从属...),而手动由命令序列定义(pre-up、up、down、post-down)
