As someone who has spent the past week or two struggling with the size-on-mds code ... IF everything is working right (a reasonably-sized IF), then it should not. AFAIK, "du" is simply calling stat(), which is the same thing "ls -l" is doing. Certainly part of the information you store as part of SOM is the disk block usage, which is what du is adding up. --Ken _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
