Just the little I've tinkered with zfs so far I'm in love already. zfs is much more responive to some kinds of things I'm used to waiting for on linux reiserfs. Commands like du, mv, rm etc on hefty amounts of data are always slow as molasses on linux/reiserfs (and reiserfs is faster than ext3). I have'nt tried ext4 but have been told it is no faster. Whereas zfs gets those jobs done in short order... very noticably faster but I am just going by feel but at least on very similar hardware (cpu wise). (The linux is on Intel 3.06 celeron 2gb ram) I guess there is something called btrfs (nicknamed butter fs) that is supposed to be linux answer to zfs but it isn't ready for primetime yet and I can say it will have a ways to go to compare to zfs. My usage and skill level is probably the lowest on this list easily but even I see some real nice features with zfs. It seams taylor made for semi-ambitious home NAS. So Brian, If you can bear with my windyness a bit more, one of the things flopping around in the back of my mind is something already mentioned here too.. change out the mobo instead of dinking around with addon pci sata controller.. I have 64 bit hardware... but am a bit scared of having lots of trouble getting opensol to run peacefully on it. Its a (somewhat old fashioned now) athlon64 2.2 ghz +3400/Aopen AK86-L mobo. (socket 754) The little jave tool that tests the hardware says my sata controller wont work (the testing tool saw it as a VIA raid controller) and suggests I turn off RAID in the bios. After a carefull look in the bios menus I'm not finding any way to turn it off so guessing the sata ports will be useless unless I install a pci addon sata controller. So thinking of justs changing out the mobo for something with stuff that is known to work. The machine came with an Asus mobo that I ruined myself by dicking aournd installing RAM... somehow shorted out something, then mobo became useless. But I'm thinking of turning to Asus again and making sure there is onboard SATA with at least 4 prts and preferebly 6. So cutting to the chase here... would you happen to have a recommendation from your own experience, or something you've heard will work and that can stand more ram... my current setup tops out at 3gb. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
