I tried with the North Carolina dataset (in GRASS 7.4.0), I had those results: </span><br>
<br>
r.volume input=elevation at PERMANENT clump=geology_30m at PERMANENT <br>
Volume report on data from <elevation at PERMANENT> using clumps on <geology_30m at PERMANENT> raster map<br>
Category Average Data # Cells Centroid Total<br>
Number in clump Total in clump Easting Northing Volume<br>
-----------------------------------------------------------------------------<br>
217 120.27 99583 828 637785.00 220865.00 9958257.22<br>
262 119.65 2765729 23115 638485.00 220415.00 276572908.36<br>
270 104.79 586004 5592 639345.00 220305.00 58600408.47<br>
-----------------------------------------------------------------------------<br>
Total Volume = 345131574.05<br>
<br>
I tried it with the GUI and on the windows command console, and I have the exact same result.<br>
It is not the same result as you, or as on the r.volume manual, but I do have the "Total Volume" line.<br>
Do you think it can be
