Hmm, yes - that can happen because you now have two RRD graph files, but
only one graph showing up on the webpage. You should have both of them
on the graph in the "trends" column, though.

Either wait 48 hours - then the root-filesystem graph will go "stale" and 
automatically be ignored on the "disk" status graph display. Or you can go
to the ~hobbit/data/rrd/HOSTNAME/ directory and delete/rename the 
"disk,root.rrd" file out of the way.
