hi.

i'm hitting a wall each time i try to format a 3 terabyte partition. i'm
able to create the partition using parted but whenever i try to create a
3 terabyte xfs or jfs or ext3 filesystem, the mounted filesystem created
is only 1 terabyte. i tried centos x86 and x86_64 4.0 but i always hit a
1 terabyte limit. please help.

    What utility are you using?
    1.1TB (1TiB) is LBA32 (signed) * 512 bytes/sector.

    It is mathematically impossible for someone who makes more than you
    to be anything but richer than you. Any tax rate that penalizes them
    will also penalize you similarly (to those below you, and then below
    them). Linear algebra, let alone differential calculus or even ele-
    mentary concepts of limits, is mutually exclusive with US journalism.
    So forget even attempting to explain how tax cuts work. ;->

    And what storage array? Driver?

    Hmmm, I didn't know GPT was an option other than on IA-64.
    Microsoft supports LDM in GPT for NT5.x (2000/XP/2003) as well.
    I'm so used to breaking up SAN and local disk volumes into less than
    1TB.

    msdos partition tables can't use >2TB partitions, you need to create a
    seperate Itanium type (forget the name) partition. Parted has this
    capability.

    However you will still need to have a seperate logical volume with an
    MSDOS partition table for booting - neither GRUB nor LILO can boot from
    the new style partitions yet.

    BTW, This issue has been covered on the list before. Search my my email
    address.

    Regards,

    John
