linux – RTNETLINK答案：执行“服务网络重启”时存在文件

sudo service network restart
sudo ifup bond0

导致以下错误(这是唯一的错误)：

Bringing up interface eth0:  RTNETLINK answers: File exists

这是涉及的接口的配置：

DEVICE="bond0"
IPADDR="10.100.48.6"
NETMASK="255.255.254.0"
ONBOOT="yes"

DEVICE="eth0"
MASTER="bond0"
SALVE="yes"
HWADDR="78:2B:CB:57:B5:B3"
NM_CONTROLLED="no"
ONBOOT="yes"

DEVICE="eth4"
MASTER="bond0"
SLAVE="yes"
HWADDR="00:1B:21:C9:F4:54"
NM_CONTROLLED="no"
ONBOOT="yes"

dmesg输出表明,当绑定驱动程序试图奴役它时,eth0还没有准备好：

dmesg | egrep '(eth0)|(bond0)'

如果网络服务停止,则路由表为空(命??令路由不显示路由).在bond0启动后可以手动设置eth0接口,它将被选为主设备,我可以在网络中ping设备.
