I recently changed which interfaces are members of my NIC bond. The first ubuntu server I made the adjustments on worked fine, but my second one has ran into issues. Ifconfig is showing a "rename2" interface present. How can I get this all straitened out?
Looking at the output of the udev rule, I want "eth2" and "eth0" to be members of the bond.
EDIT:
Okay Matt's fix below fixes this problem temporally. It returns a few reboots later and I have to repeat the process! Any ideas?

Backup the file 70-persistent-net.rules. Then clear it out 70-persistent-net.rules so that it has no entries in it. Reboot.
After reboot verify it's now looking normal.
As I recall if the persistent-net rules has any issues like mac addresses different, it'll create those rename adapters. I did have something like this happen a few months back and clearing this file helped.
Also on my systems where bonding is working, I list the bond interface first like this. Not sure if that would make things work better for you or not.
