Side question: If COW is such an old concept, why haven't there been many filesystems that have become popular that use it? ZFS, BTRFS (I think) and maybe WAFL? At least that I know of. It seems like an excellent guarantee of disk commitment, yet we're all still fussing with journalled filesystems, filesystems that fragment, buffer lags (or whatever you might call it) etc. Just stirring the pot, seems like a reasonable question (perhaps one to take somewhere else or start a new thread...) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
