  • How to partition drives larger than 2TB in size

    You will need to use parted to get this done.

    Linux Create 3TB partition size

    To create a partition start GNU parted as follows:
    # parted /dev/sdb
    Output:

    GNU Parted 2.3
    Using /dev/sdb
    Welcome to GNU Parted! Type 'help' to view a list of commands.
    (parted)

    Creates a new GPT disklabel i.e. partition table:

    (parted) mklabel gpt

    Sample outputs:

    Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost. Do you want to continue?
    Yes/No? yes
    (parted)

    Next, set the default unit to TB, enter:

    (parted) unit TB

    To create a 3TB partition size, enter:

    (parted) mkpart primary 0 0

    OR

    (parted) mkpart primary 0.00TB 3.00TB

    To print the current partitions, enter:

    (parted) print

    Sample outputs:

    Model: ATA ST33000651AS (scsi)
    Disk /dev/sdb: 3.00TB
    Sector size (logical/physical): 512B/512B
    Partition Table: gpt
    Number Start End Size File system Name Flags
    1 0.00TB 3.00TB 3.00TB ext4 primary

    Quit and save the changes, enter:

    (parted) quit

    Sample outputs:

    Information: You may need to update /etc/fstab.

    Use the mkfs.ext3 or mkfs.ext4 command to format the file system, enter:
    # mkfs.ext3 /dev/sdb1
    OR
    # mkfs.ext4 /dev/sdb1
    Sample outputs:

    mkfs.ext4 /dev/sdb1
