When a bonding device releases a slave, a warning message is printed, similar to: "bonding: bond0: Warning: the permanent HWaddr of eth0 - xx:xx:xx:xx:xx:xx - is still in use by bond0"

Issue

  • On an active bond, you may see the following warning message:
         # service network restart
         bonding: bond0: Warning: the permanent HWaddr of eth0 - 00:26:B9:xx:xx:xx - is still in use by bond0. Set the HWaddr of eth0 to a different address to avoid conflicts.
  • The service network restart command is a simple way to trigger this, basically any time a slave is released while the bond is still up, this warning will be printed.
