!!! warning "Be Careful"
When you follow these steps, you will be deleting the existing partition and immediately re-creating it. If you do not use the **EXACT SAME** starting sector for the new partition, you will destroy data. Be sure to read every annotation next to each command to fully understand what you are doing.

1. The first command needs you to enter the disk identifier. In most cases, this will likely be the first disk, such as `/dev/sda`. You do not need to indicate a partition number in this step, as you will be asked for one in a later step after identifying all of the partitions on this disk in the next command.
2. This will list all of the partitions on the disk.
3. This will ask you for a partition number to delete. Generally this is the last partition number listed. In the example below, you would type `4` then press ++enter++ to schedule the deletion of the partition.
=== "Using FDISK (Oracle / Other OS)"
``` sh
# Resize Partition of Disk in PV Group
fdisk /dev/hda # Use pvdisplay to get the disk identifier
p # List Partitions
2 # Assume Partition 2 (e.g. /dev/hda2)
d # Delete the partition
n # Make a new Partition
p # Primary Partition Type
Starting Sector: <Use Default Value>
Ending Sector: <Use Default Value>
w # Commit changes to the disk
# Probe the new partition
partprobe /dev/hda
# Reboot the Server
reboot
# Resize PV Device
pvresize /dev/hda2
pvdisplay # To Confirm size Increased
# Extend the Logical Volume for the Target Disk
lvextend -l +100%FREE /dev/VolGroup00/LogVol00 # Get this from running lvdisplay to find the correct LV
# Resize the Filesystem of the OS
resize2fs /dev/VolGroup00/LogVol00
# Validate Space increased
df -h
