On the Torque level, you can set the node offline, but that means that pbsnodes -l will report it as such. On the Torque level, you may also remove the node from the pbs_server configuration file named 'nodes' and pbsnodes -l will not report on it, because it does not belong to your cluster/system any longer. (If you go down this road, please observer that pbs_server reads the file only at startup. Perhaps there is some nice qmgr command that will remove the node from the configuration, without restarting pbs_server.) On the Maui level, you can make the node unavailable for jobs by putting it into a standing reservation, that does not allow any jobs to run within it. This can be done in the Maui configuration file or with the setres command and pbsnodes -l will not report on it. I do not know anything about the mnodectl command. If you read the src/server/UserI.c file and looks for mnodectl, you will at least see that it is only enabled for simulation mode. If this command actually existed and worked in production mode, I would presume that it would tell Torque to put the node offline, in which case pbsnodes -l would report it as offline. Perhaps you will get better advice, if you tell us why pbsnodes -l should not tell you about nodes that are offline. I would not like it not to. Perhaps you can use a command wrapper that removes all offline lines from the pbsnodes output? :-) Best regards, -- Lennart Karlsson <[EMAIL PROTECTED]> National Supercomputer Centre in Linkoping, Sweden http://www.nsc.liu.se _______________________________________________ mauiusers mailing list [email protected] http://www.supercluster.org/mailman/listinfo/mauiusers
