Create DRBD Partitions on disk
The commands below assume that /dev/sdb will be used for the DRBD partition.
device=/dev/sdb dd if=/dev/zero of=${device} obs=512 count=100 dd if=/dev/zero of=${device} obs=512 count=100 seek=$(( $(blockdev --getsz ${device}) -100 )) parted ${device} "mklabel gpt" parted ${device} "mkpart primary 0% 100%"
Verify that the partition is created:
fdisk -l /dev/sdb --> WARNING: fdisk GPT support is currently new, and therefore in an experimental phase. Use at your own discretion.
