I don't see why you'd need that. The only differences you might have would
be if you're mounting different volumes on different servers.
You could homogenise that even further by simply using *localhost* instead
of the server's FQDN.

On the more recent versions (3.7+ at least), if you're mounting through
fuse you no longer need to define backup servers, gluster deals with that
internally. One mount option I would add would be "relatime".

I don't see it'd make much difference. If it's lots of small files though,
there could be a performance hit. If it did become an issue, it might be
more efficient exporting snapshots (assuming your bricks are backed by LVM.
ZFS would make it even easier).

Again, no need. The replica translator does that for you.
