Without size-on-mds, either way would have to query both the mds and each OST to get the size info. Not being that familiar with size-on- mds, it does seem likely that "du" would still have to query the OST for size info, even when "ls -l" does not. > Am I missing something? > > [1] http://storm.forge.cnaf.infn.it/home > > > Chris > > _______________________________________________ > Lustre-discuss mailing list > [email protected] > http://lists.lustre.org/mailman/listinfo/lustre-discuss _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
