We use mmsdrrestore after the node boots. In our case these are diskless nodes provisioned by xCAT. The post install script takes care of ensuring infiniband is lit up, and does the mmsdrrestore followed by mmstartup. -- ddj Dave Johnson On Jan 29, 2021, at 2:47 PM, Ruffner, Scott (jpr9c) <[email protected]> wrote: 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? -- Scott Ruffner Senior HPC Engineer UVa Research Computing (434)924-6778(o) (434)295-0250(h) [email protected] _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss
