Volume names can be kept as your convenience.

The doc is quite unclear for me as a gluster newbie. It's the old Linux
paradox: the moment that you will understand the docs is the moment
that you don't need them anymore.

Why is there a MASTER_VOL and a SLAVE_VOL? If I have a volume called
"gvol0" it seems logical to me that the geo-replication slave server
also uses this volume name "gvol0". The geo-replication server knows
it
is not part of the active cluster because it was told to do so.

OTOH, I think there must be an obvious reason for this MASTER_VOL and
SLAVE_VOL, but I don't understand this from the docs.
