我有上面的场景，其中服务器的bond0接口连接到服务器的 SW1 和 SW2 相关接口，昨晚以某种方式SW1重新启动，服务器失去eth0连接，但每次交换机成功重新启动后，它也没有故障转移到 eth1 网络关闭，这发生在多台服务器上不是单身。所以最后我在所有服务器上重新启动网络以使其正常工作。我们已经primary=eth0在 bond0 配置中进行了设置。
ifcfg-bond0
DEVICE=bond0
BOOTPROTO=none
ONBOOT=yes
BONDING_OPTS=mode=1 arp_interval=1000 arp_ip_target=192.168.10.1 miimon=500 downdelay=1000 primary=eth0 primary_reselect=always
NETMASK=255.255.255.0
IPADDR=192.168.10.20
GATEWAY=192.168.10.1
ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
ifcfg-eth1
DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
这就是发生这种情况时我在日志中看到的内容
