<p class="MsoNormal"><span lang="EN-AU">Apologies in advance if this has been covered already in discussions.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">I’m building a new spectrum scale cluster and I am trying to get consistent device names across all nodes. I am attempting to use aliases in the multipath.conf which actually works and creates the /dev/mapper/<disk name>
link. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">I understand you can also copy the bindings file but I think aliases is probably easier to maintain.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">However Spectrum scale will not accept the /dev/mapper device it only looks for dm-X devices that are in the /proc/partitions file. I know SONAS is pointing to Device mapper so there must be a way?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">Im looking at the /var/mmfs/etc/nsddevices is it a case of editing this file to find the /dev/mapper device?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">Appreciate the help in advance,<o:p></o:p></span></p>
