With the newer versions they are really pushing away from having to
manually configure bits.  As long as your client is configured to pull its
configuration file from the server when you run the command on the server
the client should get an updated config file.

You should be able to look in the clients log file and see the fact that
the config file updated (I don't have an example at the moment).

Another way you can check this is if the number of connections from the
client to the server (netstat -pant | grep gluster | wc -l) increases after
you make the change. (should increase by the count of bricks in the volume
i believe).
