Why not work with the CentOS 7 kernel on the server anyway? Is something your LND needs not available? CentOS 7 is freely available and isn't far off in terms of kernel version from 3.12.<span style="color:#1F497D"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Yes –I’m somewhat stuck on RHEL 6.x series as I use warewulf as a cluster provisioning system (diskless compute nodes), so far have not found a functional warewulf for RHEL7.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I did choose linux-3.12.39 as a kernel base believing it to be somewhat close to RHEL7; although I’m finding this to less so than hoped for….<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Additionally the RD drivers I’m using have not been ported to RHEL7;
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">In examining lustre-2_7.62 I found support for sles12 based on 3.12.39 kernel.; thinking the lustre patches would be close…<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">So now I’m wedged between RHEL7 ldiskfs patches and SLES12 ldiskfs patches – figure out distro specific enhancements vs lustre enhancements.</span><br>
<br>
You may be hard pressed to get useful advice on changing the ldiskfs patch series, that has the potential to be a pretty big job.<span style="color:#1F497D"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I’m starting to understand the magnitude of the ldiskfs task…….<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I’m ignorant about zfs*, would zfs be a better (read that as path-of-least-resistance) approach ? What are the zfs pitfalls?<o:p></o:p></span></p>
