Thanks Andy.
<div class=""><br class="">
</div>
<div class="">I think i omit a big step which is copying the /etc/munge/munge.key from master/headnode to all the /etc/munge/munge/key in the nodes - am i right? i dont recall doing this so that could be the problem.</div>
<div class=""><br class="">
</div>
<div class="">Is there a specific command i need to do to copy the munge.key from the master/headnode to all the nodes?</div>

<div class="">Thank you for your help and sorry for such “beginner” questions.</div>
