Creating a partition for a new drive

Creating partitioons for a new drive:

Using the fdisk -l command find the new disk. Let it be /dev/sda.

Once you give fdisk /dev/sda and 'n' it will ask whether primary or secondary partition. It will ask for the starting block number. Get the information from fdisk -l and give the number Then it will ask the size. Give +sizeM (Eg: +5000M).

fdisk /dev/sda
m - Help
n - new partition
w - To save and quit
mkfs -t ext3 /dev/sda1

If the new partition created is an extended partition, after creating the partition, run partprobe. Then again create a logical partition of required size using

fdisk /dev/sda
mkfs -t ext3 /dev/sda5
mount /dev/sda5 /vz

Note:  partprobe is a program that informs the operating system kernel of partition table changes, by requesting that the operating system re-read the partition table.  Thus partprobe helps to create a new file system without rebooting the box.
