<p class="MsoNormal"><span style="font-size:11.0pt">We want all of our compute nodes (bare metal) to directly participate in the cluster as client nodes; of course, they are sharing a common root image.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">Adding nodes via the regular mmaddnode (with the dsh operation to replicate files to the clients) isn’t really viable, but if I short-circuit that, and simply generate the /var/mmfs/gen files and then manually
copy those and the keyfiles to the shared root images, is that safe?<o:p></o:p></span></p>
