I start to wonder if those tmp files created are in any way compressed<br>
(probably not?). This may be worth a bug ticket at<br>
<a href="https://trac.osgeo.org/grass/newticket" rel="noreferrer noreferrer" target="_blank">https://trac.osgeo.org/grass/newticket</a><br>

<br>
So the grassdata directory with the location and mapset in question is<br>
on the terabyte disk?<br>

<br>
I think we should try to improve the error message, telling on which<br>
device this occurs.<br>
<br>
The code in question is:<br>
vector/v.vol.rst/main.c, line 633<br>
<br>
/* filling temp file with zeroes */<br>
for (i = 0; i < n_rows; i++) {<br>
if (!<br>
(fwrite<br>
(zero_array_cell, sizeof(FCELL), n_cols, Tmp_fd_cell))) {<br>
clean();<br>
G_fatal_error(_("Not enough disk space - cannot<br>
write temp files"));<br>
}<br>
}<br>
<br>
Does anyone know how to get a better error message?<br>
Would this help?<br>

Are the pixels/voxels non-square on purpose? This could be adjusted<br>
with g.region.<br>

That is still a lot (just guessing around):<br>
240,690,193,689 raster3d_cells * 64 bit (but it will be larger than<br>
32bit) = 1.540417e+13 bit<br>
<br>
So, in the first place we need to know where GRASS GIS really writes<br>
to in your system.<br>
<br>
Any devs having a suggestion here?<br>
