<div dir="ltr">Hello,
<div><br>
</div>
<div>Short way: Is there any way to define a preferred Gluster
server ?<br>
<div><br>
</div>
<div>Long way:</div>
<div>I have the following setup (version 3.6.3) :</div>
<div><br>
</div>
<div>Gluster A <==> VPN <==> Gluster B</div>
<div><br>
</div>
<div>Volume is replicated between A and B.</div>
<div><br>
</div>
<div>They are in same datacenter, using a 1Gb/s connection,
low latency (0.5ms)</div>
<div><br>
</div>
<div>I have gluster clients in lan A & B.</div>
<div><br>
</div>
<div>When doing a "ls" on big folder (~60k files), both
gluster node are used, and so it need 9mn instead on 1mn if
only the local gluster is reachable.</div>
<div><br>
</div>
</div>
</div>

Lookups (and writes of course) from clients are sent to both bricks
because AFR uses the result of the lookup to select which brick to
read from if there is a pending heal etc.<br>
If the file is clean on both A and B, then reads are always served
from the local brick. i.e. reads on clients mounted on A will be
served from the brick in A (and likewise for B).<br>
<br>
Hope that helps,<br>

<div>It's HA setup, application is present on both side. I
would like a master/master setup, but using only local node
as possible.</div>
