It may be worth noting cp could nonetheless be made (mostly) COW by being clever about noticing recently-read data being written back. Hammer2 does this. At [0]: "... This means that typical situations such as when copying files or whole directory hierarchies will naturally de-duplicate. Simply reading filesystem data in makes it available for deduplication later." I have no idea whether that would be appropriate for gefs. -- James [0] http://apollo.backplane.com/DFlyMisc/hammer2.txt
