Hello ! I have come across some weirdness, i would like to understand.
it`s not an issue, but i`m just wondering about. i created two zfs filesystems based on image-files used as devices - i.e. i created them on top of two empty files, exactly the same size. then i enabled compression on one of them (zfs set compression=on compressedzfs) after copying a large file to both filesystems, i unmounted them, exported them and did a gzip on those zfs imagefiles. after gzipping, the imagefile with compression=on is nearly twice as big as the imagefile with compression=off. this is something i wouldn`t have expected. ok, i didn`t expect the same size, but i never would have expected such BIG difference, since we are basically re-compressing data which is already compressed. what`s causing this effect? can someone probably explain this ? regards roland This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
