If you unlink the original name/inode entry you can mark it as deleted without actually deleting it, thus leaving extant links to it live and fresh; you only have to chase down the other links when the original's directory is removed, though you can do the same to directories, deferring actual removal to later (at the cost of wasting disk space and complicating accounting). And/or you can always lazily update back references, if you throw in a log, so that you can find those when they are needed. Note that this assymetric hard-linking approach makes original links fast and others slow; this will surely bother someone :) Nico -- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
