<p>Hi Peter,</p>
<p>Thanks for the quick answer.</p>
<p>The exact server version we are running is 2.12.5. Do you see an potential issue running such a server version with clients version 2.15.6?</p>
<p>Furthermore, i would like to know how long will the 2.12.x ( latest x=9) lustre server version be updated/supported ? </p>
<p>Do you know?</p>
<p>Cheers,</p>
<p>Denis</p>

\u2013 we test interoperability with the latest 2.12.x release as part of the pre-release validation for 2.15.x releases.</span></p>

<p><span style="font-family:"Calibri",sans-serif; color:black">We have a server version 2.12 which can interoperate without problem with higher lustre client versions ( up to 2.15.6 at the moment ).</span></p>
<p><span style="font-family:"Calibri",sans-serif; color:black">My question is how long can we update the client version on our compute nodes without having problem with the "old" luster server version 2.12?</span></p>
