I have some custom edits to this file, so that is why they won't match. 
  Since we're using inodes in troubleshooting, here is the def I'm using:

[inode]
         FNPATTERN inode(.*).rrd
         TITLE inode Utilization
         YAXIS % Full
         DEF:p at RRDIDX@=@RRDFN@:pct:AVERAGE
         LINE2:p at RRDIDX@#@COLOR@:@RRDPARAM@
         -u 100
         -l 0
         GPRINT:p at RRDIDX@:LAST: \: %5.1lf (cur)
         GPRINT:p at RRDIDX@:MAX: \: %5.1lf (max)
         GPRINT:p at RRDIDX@:MIN: \: %5.1lf (min)
         GPRINT:p at RRDIDX@:AVERAGE: \: %5.1lf (avg)\n

I will check this file further and see if my custom edits are still 
necessary, but would it make sense to blame the def if the graphs in the 
trends column are right while the inode column is not?  I would think 
that since they likely use the same def, the graph would be broken in 
both places.

Sure, they look fine (example below).  The graphs in the trends column 
have all the current data and qtrees/inode/disks, and I can query the 
rrd files themselves with rrdtool and the data looks fine.

ls -l inode,vol,*
-rw-r--r--    1 bb       bb          38532 Oct 14 09:34 
inode,vol,prod01,.rrd
-rw-r--r--    1 bb       bb          38532 Oct 14 09:34 
inode,vol,prod02,.rrd
-rw-r--r--    1 bb       bb          38532 Oct 14 09:34 inode,vol,vol0,.rrd
