We've already asked our Netapp representative. She said it's not hard to add that. > I'd suggest whether you can restructure your code and work without this. It would require touching code for which we don't have sources anymore (people gone, too). It would also require to create hard links to the results files directly, which means linking 15000+ files per directory with a minimum of 30000 directories. Each day (this is CERN after all). The other way around would be to throw the SPARC machines away and go with Netapp. > For one, it requires the application to run with root (older versions) or > with specific privileges which aren't, e.g., available in non-global zones. The code runs with privileges anyway. Lionel _______________________________________________ zfs-discuss mailing list email@example.com http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
