<div>I think the node was not added to the cluster, but some changes on the node itself took place already (like creating /var/mmfs/gen ... and possibly others)</div>
<div><br>
There is/was a chapter/appendix to the GPFS Adminstration Guide, telling how to permanently remove GPFS from a node, that might help on how to stop the mmaddnode command to cope with a node already belonging to a cluster ...</div>

</div>
<div><br>
</div>
<div>I was trying to add a node to the cluster but after an hour I ctrl-c it <br>
</div>
<div>as it was clearly not in a good place. It told me that it didn't make <br>
</div>
<div>changes<br>
</div>
<div><br>
</div>
<div>^Cmmdsh: Caught SIG INT - terminating the child processes.<br>
</div>
<div>mmaddnode: Interrupt received: No changes made.<br>
</div>
<div><br>
</div>
<div>I checked to make sure all the networking is correct, GPFS packages are <br>
</div>
<div>installed on the node etc. and it is all good so I go to add it again and<br>
</div>
<div><br>
</div>
<div>mmaddnode: Node <##### censored> was not added to the cluster.<br>
</div>
<div> The node appears to already belong to a GPFS cluster.<br>
</div>
<div>mmaddnode: mmaddnode quitting. None of the specified nodes are valid.<br>
</div>
<div>mmaddnode: Command failed. Examine previous error messages to determine <br>
</div>
<div>cause.<br>
</div>
<div><br>
</div>
<div>Ok, lets try and delete it<br>
</div>
<div><br>
</div>
<div>mmdelnode: Incorrect node <##### censored> specified for command.<br>
</div>
<div>mmdelnode: No nodes were found that matched the input specification.<br>
</div>
<div>mmdelnode: Command failed. Examine previous error messages to determine <br>
</div>
<div>cause.<br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>Trying to do mmsdrrestore on the node gives<br>
</div>
<div><br>
</div>
<div>mmsdrrestore: There is no record for this node in file <br>
</div>
<div>gpfs0:/var/mmfs/gen/mmsdrfs.<br>
</div>
<div> Either the node is not part of the cluster, or the file is for a <br>
</div>
<div>different cluster,<br>
</div>
<div> or not all of the node's adapter interfaces have been activated yet.<br>
</div>
<div>mmsdrrestore: Command failed. Examine previous error messages to <br>
</div>
<div>determine cause.<br>
</div>
<div><br>
</div>
<div>The node does not show up in mmlsnode or mmlscluster<br>
</div>
<div><br>

<div>Anyone and idea what is going on?<br>
