[gpfsug-discuss] Get list of filesets _without_ running mmlsfileset?

I suppose you could run the underlying tslsfileset, though that's probably
not the answer you're looking for.

Out of curiousity, what are you hoping to gain by not running mmlsfileset?
Is the problem scaling due to the number of filesets that you have defined?

There are obviously multiple issues with that, so the workaround we???re using for now is to have a cron job which runs mmlsfileset once a day and dumps it out to a text file, which the script then reads.  That???s sub-optimal for any day on which a fileset gets created or deleted, so I???m looking for a better way ??? one which doesn???t require root privileges and preferably doesn???t involve running a GPFS command at all.
