Hi there,
I have just finished writing an initial version of 'lsgvt':
This program shows a pretty graphical representation of a Gluster volume's topology. It uses the fuse-{volname}.vol file for it's source. If you do not give any parameters, it shows the topology for all the volumes, otherwise it will show the topology for the given space-separated list of volume names.
You can find it on github
here.
Have fun with it. If you have any comments or feature requests, just let me know.
Regards,
Fred van Zwieten
