settings in /etc/glusterfs/glusterd.vol are meant for the management daemon i.e. glusterd.

All tuning needed for volume services would need to be done through the "gluster volume set" interface.

Yes, all these translators are ON by default.

gluster client properties cannot be set per client through "volume set" CLI. The properties altered through "volume set" are applicable to all clients by default. Per client behavior can be altered at the time of mounting a gluster volume.
