By the way - if you are not using raid then two of the disks are not
connected. I suspect you set up RAID 6 by mistake.

    Can you cut and paste the fdisk -l output into an email? It can tell
    you a lot about what the drives really amount to.

    Are you running it as a RAID with checksum or simply striping? Your
    numbers suggest something like RAID 6.

    This is the system I am currently prepping to use as a name server,
    firewall, and email tool for a two person multi-computer (and a lot
    of "gadgets") network here.

    Partition 1 does not end on cylinder boundary.

    The header portion is REALLY interesting. It's a 500 gigabyte
    drive. But, it's only 488386584 1k blocks, 476940 1 meg blocks, or
    465 1 gigabyte blocks when speaking of 1024 byte entities rather
    than 1000 byte entities.

    Your 12 1 terabyte disks striped array is only 10.91 TeraBytes
    in computer speak - 1024 per K rather than 1000 per k. Could
    that explain your discrepancy?

           disks should be advertised both ways for clarity.)

        Hi,

        Ans: / = ~45GB
        /boot =~2GB
        /swap =~16GB


        I have another question

        why gparted, fdisk -l, system-config-lvm are giving different
        outputs for
        12TB but giving the same output for 500GB

        With Regards

                Could it be that he's comparing the "1TB" drives he's bought
        (which are
                marketed as decimal 1x10^12 bytes) with the expected
        (binary) 2^40
                bytes?

                That's a 10% reduction in perceived space.  If the disk
        format has also
                reserved the traditional (and now obsolete) 10% for root use
        only, then
                suddenly we're 2.5 TB down from what one would naively
        expect after
                clicking on "Newegg, please send me 12 terabyte drives".

                gparted will show the whole capacity (ignoring this root
        reserve), but
        "df" won't.


            How big are /, /boot, and /swap?







            (I'm old fashioned and silly, I like "/dev/fdisk -l /dev/sda
         >foo" as
            a way of exporting the actual partitioning. I am not sure fdisk
        would
            be happy with 12 TB, though. But showing us the actual partitioning
            might be a good idea.)
