My best favorite disk partition table manipulation tools are
fdisk on Linux. However, for large disks,
fdisk (of the versions by this post is written) will just give up with a message suggesting GPT partition table format and using GNU
WARNING: The size of this disk is 6.0 TB (6001042391040 bytes). DOS partition table format can not be used on drives for volumes larger than (2199023255040 bytes) for 512-byte sectors. Use parted(1) and GUID partition table format (GPT).
If you continue using
cfdisk, you will only create msdos partition table and use only less than 2TB space.
pc ~ # parted /dev/sdc GNU Parted 2.3 Using /dev/sdc Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) mklabel GPT Warning: The existing disk label on /dev/sdc will be destroyed and all data on this disk will be lost. Do you want to continue? Yes/No? Yes (parted) mkpart primary 2048s 100% (parted) q Information: You may need to update /etc/fstab.
Why "2048s" is used here? Please check this blog post.
For the command
mkpart primary 2048s 100%, an alternative command is
mkpart PARTITION_LABEL ext4 primary 2048s 100%
which makes a partition with label PARTITION_LABEL.
The partition can be easily accessed later at path
/dev/disk/by-partlable/PARTITION_LABEL which will be useful for writing
fstab entry or other usages that need to directly use a partition block device.
The new partition
/dev/sdc1 is created:
pc ~ # ls /dev/sd* /dev/sda /dev/sda1 /dev/sda2 /dev/sda3 /dev/sda4 /dev/sda5 /dev/sdb /dev/sdb1 /dev/sdc /dev/sdc1
Check the information again:
pc ~ # parted /dev/sdc print Model: ORICO H/ W RAID0 (scsi) Disk /dev/sdc: 6001GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 6001GB 6001GB primary
parted: if you don’t want to use
parted, you may try
cgdisk which is a curses-based GPT manipulator that feel very similar to
