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.<br>

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.<br>

Gluster 3.4 server bits with 3.6 client bits should work
fine. <br>
<br>
But I think the reserve (i.e. 3.6 server bits with older
client bits) are not compatible because of below issues<br>
<ul>
<li>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.<br>
</li>
<li>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.</li>
</ul>
<p>Thanks,<br>
Lala<br>
