Have you tested this configuration?  iic, the 'AFR' module  (
replication)  introduced its 'Version 2' implementation in 3.6 which is not
compatible with its older version. The GlusterFS 3.4 & 3.5 versions are
shipped with "AFR V1" , so I really doubt the mentioned configuration will
work perfectly.  AFR guys can confirm though.
