If I recall correctly, bonding changes  the name of the network
interface which confuses the heck out of OSCAR.  I would run
$OSCAR_HOME/scripts/start_over (with the unbonded network settings
prefferably) and then run "install oscar" with the bonded interface
name.

This assumes your image is up to date (or new), in which case you
shouldn't really lose anything besides having the cluster down for a
bit.
