<p class="MsoNormal">Hi all, I hope I haven't missed something obvious in the docs here but I am confused about versions.<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'm trying to install the lustre client on a Centos 8.2 system with the 4.18.0-193 kernel, which is an un-updated kernel.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">The client install instructions at [1] say to look at the changelog [2] for the list of supported kernels. There, that kernel is only listed against the unreleased 2.14.0 version. However the Lustre Support Matrix at [3] shows RHEL 8.2
as a client using 2.12.5. Does that mean 2.12.5 will work with the above kernel, or should I use another kernel with that OS version? If the former, how come it's not listed in the changelog?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">On a related note the changelong only shows 2.x.0 versions - is kernel compatibility the same for all 2.x.y versions for the same x?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">many thanks for any help<o:p></o:p></p>
