[gpfsug-discuss] Adding client nodes using a shared NFS root image.

Hi everyone,

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.

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?

Am I going about this the entirely wrong way?
