The native filesystem of the Fujitsu Siemens mainframe operating system "BS2000/OSD" does that: - if a file is deleted with the DELETE-FILE command, using DESTROY=*YES parameter - if a file that is deleted has its DESTROY attribute set to *YES (even if the DESTROY parameter isn't used in the DELETE-FILE command). I think the defragmentation tool (spaceopt) respects the DESTROY attribute as well. If my memory serves me well, the default value for the DESTROY fileattribute can be determined per volumeset (=catalog=filesystem). >-- >Andrew -- ( Kees Nuyt ) c[_] _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
