[GRASS-user] Buffer one side

I need to create a buffer only on one side (i.e. left side) of the lines of a
shapefile? Is that possible?

One solution I can see is to create the buffer first than split the resulting buffer with the line you just buffered. I believe you can split a polygon with a line by using the command v.overlay

Finally, I think the solution is to use v.parallel -b

I run the command using v.parallel -r -b. It was running for almost 4 hours
and it didn't end. The input file has only one line (coastline). Why is this
so slow? Is that a bug or does it need more time to finish? Could it be
something wrong with my input file?
