No, I didn't.

I am very interested about these settings.

Also, is it possible to turn the shard feature AFTER the volume was 
started to be used ?

>> Hi Carl, Did you check for any pending heals before rebooting the gluster server? Also, it was discussed that shutting down the node, does not stop the bricks properly and thus the clients will eait for a timeout before restoring full functionality.  You can stop your glusterd and actually all processes by using a script in /usr/share/gluster/scripts (the path is based on memory and could be wrong).
