Humble,<br>
<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>
