Add New Partitions and Logical Volumes

Introduction

In this challenge, you will learn how to configure local storage on a Linux system by adding new partitions and logical volumes, as well as creating a swap space, without causing any data loss. This skill is essential for system administrators to efficiently manage and expand the storage capacity of their Linux servers.

Add New Partitions and Logical Volumes

Tasks

• Create a new partition on the system's storage device.
• Create a new logical volume group using the new partition.
• Create a new logical volume within the new volume group.
• Format the new logical volume with an appropriate file system.
• Mount the new logical volume to a suitable directory.

Requirements

• The new partition should be created on the /dev/sdb device.
• The new partition should have a size of 2 GiB.
• The new volume group should be named vg_project.
• The new logical volume should be named lv_project and have a size of 1 GiB.
• The new logical volume should be formatted with the ext4 file system.
• The new logical volume should be mounted to the /home/labex/project directory.

Example

After completing this step, the output of lsblk and df -h commands should look similar to the following:

$ lsblk
NAME                    SIZE TYPE MOUNTPOINT
sda                     40G  disk
├─sda1                   1G  part /boot
└─sda2                  39G  part /
sdb                     10G  disk
└─sdb1                   2G  part
  └─vg_project-lv_project
                         1G  lvm  /home/labex/project

$ df -h
Filesystem                   Size  Used Avail Use% Mounted on
/dev/sda2                     39G  1.2G   36G   4% /
/dev/sda1                     1.0G  135M  816M  14% /boot
/dev/mapper/vg_project-lv_project
                              1.0G   33M  920M   4% /home/labex/project

Summary

In this challenge, you learned how to configure local storage on a Linux system by adding new partitions and logical volumes, as well as creating a swap space, without causing any data loss. You practiced creating a new partition, a new volume group, a new logical volume, formatting the logical volume, and mounting it to a suitable directory. This skill is essential for system administrators to efficiently manage and expand the storage capacity of their Linux servers.
