I would tend to think the mmaddnode would fail, as GPFS recognizes that this node is already part of an existing cluster (due to the content of /var/mmfs) So following the steps in the admin guide, how to permanently remove GPFS from a node (related to the /tmp/mmfs and /var/mmfs dir) would be recommended
