如果遇到下面的错误信息，可以采用下列方式：

Bringing up interface bond0: Device bond0 does not seem to be present, delaying initialization. 


解决办法：

# modprobe bonding

# lsmod |grep bonding 


执行以上两行后就可以支持bond了

# cat /etc/rc.d/network.sh      // add this scripts to /etc/rc.local for automatic start

  • Bond错误

   

ISSUE

   

   Ethernet Channel Bonding Driver: v2.6.3-rh (June 8, 2005)

   bonding: Warning: either miimon or arp_interval and arp_ip_target module 

   parameters must be specified, otherwise bonding will not detect link failures! 

   see bonding.txt for details.

   divert: allocating divert_blk for bond0


SOLUTION

Properly setup bonding alias in "/etc/modprobe.conf"


## setup bond0 alias and set it's option in 

##    /etc/modprobe.conf

##

## NOTE:

##    miimon=100 (100 msecs) [Media Independent Interface (MII) link 

monitoring]

##    mode=1     (bond mode) ["1" is "active-backup" mode]

##

##

vi /etc/modprobe.conf

--- add the following to the end of the file ---

alias bond0 bonding

options bond0 miimon=100 mode=1



   [root@rac1 log]# grep bond0 /etc/modprobe.conf

   alias bond0 bonding

   options bond0 miimon=100 mode=1
