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.

That is right. Usually newer clients would work with older servers but
3.6 saw a complete rewrite of AFR (afr-v2) which is not fully compatible
with AFR-v1. It would be best to update the all the clients to 3.6 as well.

afacit, this will *not* work and its *not* supported.
Humble,
Gluster 3.4 server bits with 3.6 client bits should work fine.
But I think the reserve (i.e. 3.6 server bits with older client
bits) are not compatible because of below issues
* Older clients can not mount the newly created volume on 3.6 .
This is because readdir-ahead will be enabled on the volume by
default which isn't present in older clients.
* We can't run rebalance on any volume created with 3.6 bits (
with or without readdir-ahead) when older clients are
connected. The rebalance command will error out if older
clients are connected.
Thanks,
Lala

You mean 3.6.2 client bits with v3.4 servers? yes, it should
work fine.
