Linux

Create new partition with parted:

# mbr
parted /dev/sda mklabel msdos
parted /dev/sda mkpart primary ext4 0% 100%

# gpt
parted /dev/sda mklabel gpt
parted /dev/sda mkpart part-label ext4 0% 100%

Note that ‘part-label’ cannot be empty, to remove: fdisk /dev/sda x n <enter> r w

To resize: parted /dev/sdX then resizepart X

Clone MBR partition table:

Use sfdisk:

sfdisk -d /dev/sda > partitions.txt
sfdisk /dev/sdb < partitions.txt

sfdisk -d /dev/sda | sfdisk /dev/sdb
sfdisk -d /dev/sda | sfdisk --force /dev/sdb
