5 删除 bond 设备
当我们需要删除bond设备的时候,该如何删除呢？请看下面操作
1.查看网络设备
[root@localhost ~]# ls /sys/class/net/ bond0 bond1 bonding_masters eno16777736 eno33554960 eno50332184 eno67109408 eno83886632 lo
2.删除bond网络设备
直接删除bond0，会提示无权限。
可以通过bonding_masters文件删除bond设备,但是bonding_masters文件是无法直接修改的。
[root@localhost ~]# echo -bond0 >/sys/class/net/bonding_masters
echo 后面的 ‘-’ 是删除设备，‘+’是增加设备
