Vamos começar com o comando fdisk para verificar o disco:
# fdisk -l /dev/sda
WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.
WARNING: The size of this disk is 9.3 TB (9345848836096 bytes).
DOS partition table format can not be used on drives for volumes
larger than 2.2 TB (2199023255040 bytes). Use parted(1) and GUID
partition table format (GPT).
Disk /dev/sda: 9345.8 GB, 9345848836096 bytes
255 heads, 63 sectors/track, 1136234 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Bom, o fdisk nos informa que temos que usar o GNU Parted, pois não tem suporte a GPT. Pode consultar a man page:
# man parted
Começando a formatação:
# parted /dev/sda
GNU Parted 1.8.1
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) mklabel gpt
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)
Em seguida, definir a unidade padrão para TB, digitar:
(parted) unit TB
Vamos criar a partição:
(parted) mkpart primary 0.00TB 9.35TB
Vamos visualizar como ficou:
(parted) print
Disk /dev/sda: 9.35TB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size & nbsp; File system Name Flags
1 0.00TB 9.35TB 9.35TB ; primary
Vamos sair:
(parted) quit
Information: Don't forget to update /etc/fstab, if necessary.
Ok, vamos usar o mkfs para formatar:
# mkfs.ext3 /dev/sda1
mke2fs 1.39 (29-May-2006)

Verificando como ficou:

Note como ficou o meu /dev/sda1 no número de blocks.
Agora vamos montar o mesmo:
# mount /dev/sda1 /Backup
