Looks like having the port be configurable through the gluster command would be a very good feature enhancement <hint, hint> :-)

Currently, there is no option to change the port through options, hence you need to change the code.

information, and 'glusterd' will remember this. Hence every time you restart the volume, the same port gets assigned to it. One of the option is to delete the volume and create it with the same command (which was used earlier).

Yes, you can change this in code, and re-compile to get it working.
libglusterfs/src/globals.h:23:#define GF_DEFAULT_BASE_PORT 24007
