After I rebooted one of my servers, Munin (which runs on another server) seems to have picked up some garbage response from it in the process of rebooting.

I would like to remove that garbage value, even if it means losing all the data for that node up to now. I tried removing the .rrd files in /var/lib/munin but all that did was remove the history from before the reboot. Is there a way to clean this up?
