<div>Hmm. Perhaps one of the end user sites will speak up with something that they have tried successfully but I cannot think of anyone that I have heard running RHEL 5.x on the Lustre servers but RHEL 7.x on the Lustre clients. Why os there a reluctance to
upgrade the OS on the storage servers? Is it older storage not supported on supported with newer version of RHEL?</div>

<div dir="ltr">Hello,
<div>We have an existing HPC running Lustre 1.8.7 on RHEL 5.4</div>
<div>The Lustre servers (MDS and OSS) are all running RHEL 5.4</div>
<div>The Lustre clients(HPC compute nodes) are also running RHEL 5.4</div>
<div>Now the management has decided to upgrade the compute nodes to RHEL 7.</div>
<div>But they do not want to upgrade the OS of Lustre Servers which is still RHEL 5.4</div>
<div>So the question is will this configuration work where the Lustre clients are RHEL 7 and Lustre server are all running RHEL 5.4?</div>
<div><br>
</div>
<div>Thanks.</div>
