Step-by-Step Guide to Linux Extend Partition with LVM

Managing disk space efficiently is crucial for Linux system administrators. Linux Extend Partition The Logical Volume Manager (LVM) simplifies this task by allowing dynamic resizing of partitions without system downtime.

Linux Extend Partition with LVM Objectives:

Install a new hardware disk drive
Create a new partition
Create a physical volume (PV)
Extend the volume group (VG)
Extend the logical volume (LV)
Resize the file system
Verify the mount point

Linux Extend Partition with LVM Prerequisites:

Basic knowledge of Linux commands
Access to a Linux system with root or sudo privileges
Familiarity with a terminal or command-line interface

NOTE:

Adjust partition names (/dev/sda, /dev/sda1, etc.) according to your server setup and file system for accurate functionality and fit.

Action Plan:

Step 1 :

Install a New Hardware Disk Drive:

The List of all available disks.

lsblk

Identify the new disk with

fdisk -l

Step 2 :

Create a New Partition:

Launch fdisk for the new disk:

fdisk /dev/sdf

Enter the following commands within fdisk:

n (create a new partition)
p (primary partition)
Specify partition number and sector values, or use default values.
Change the partition type to Linux LVM (hex code 8e).
w (write changes and exit).
Create a Physical Volume (PV):

Step 3 :

Create a physical volume:

pvcreate /dev/sdf1

Verify the new physical volume:

pvs

pvdisplay

Step 4 :

Extend the Volume Group (VG):

vgextend vg1 /dev/sdf1

Verify the volume group:

vgs

or

vgdisplay

Step 5 :

Extend the Logical Volume (LV):

lvextend -L +500M /dev/vg_name/lv_name

Step 6 :

Resize the file system on the logical volume:

resize2fs /dev/vg_name/lv_name

Step 7 :

Verify the Mount Point:

Ensure the mount point reflects changes:

lsblk

df -TH

We have successfully extend the mount points ‘/a01‘ and ‘/a02‘.
