We are running the mmbackup on an AIX system oslevel -s 6100-07-10-1415 Current GPFS build: "4.1.0.8 ".
So we only use one node for the policy run.

What version of GPFS are you running? How many nodes are you using? Are you using a "-g global shared directory"? The original mmapplypolicy code was targeted to a single node, so by default it still runs on a single node and you have to specify -N to run it in parallel. When you run multi-node there is a "-g" option that defines a global shared directory that must be visible to all nodes specified in the -N list. Using "-g" with "-N" enables a scale-out parallel algorithm that substantially reduces the time for candidate selection. -Wayne _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss ------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------ Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
