Look at where gmetad is storing the rrd files now. You can find it in
your gmetad.conf under rrd_rootdir. Maybe you didn't specify it for one
of the instantiations. The default location is /var/lib/ganglia/rrds.
Maybe you are running gmetad as a different user? See if the file names
have changed or if something changed in the host name resolution on the
gmetad host.
If the frontend is talking to a different gmetad, that could be your
issue as well (read: longshot).
Good luck,
Ian
