Install LVM on Ubuntu: Step-by-Step Guide

The steps to install LVM (Logical Volume Manager) in Ubuntu are as follows:

1. Install the LVM package.
2. Update the system by running “sudo apt update” and then install the LVM2 package using “sudo apt install lvm2”.
3. Make sure the LVM kernel module is loaded.
4. Please load the dm-mod module using sudo.
5. Create a Physical Volume.
6. Initialize a physical volume on the device /dev/sdX using superuser privileges.
7. Create a Volume Group:
8. Create a volume group named vg_name using the device /dev/sdX with superuser permissions.
9. Create a logical volume.
10. Create a logical volume with a specified size and name, within a volume group.
11. Format logical volume:
12. Create an ext4 filesystem on the logical volume lv_name in the volume group vg_name.
13. Mount logical volume:
14. Create a new directory named “lv_name” inside the “/mnt” directory, and then mount the logical volume named “lv_name” from the volume group named “vg_name” to the newly created directory.
15. Permanent mounting of logical volumes (optional):
    Adding the information of the logical volume to the /etc/fstab file so that the system automatically mounts the logical volume after restarting.

Please replace the device name (/dev/sdX), volume group name (vg_name), logical volume name (lv_name), and size as necessary. After installing LVM, you can create, adjust, and manage logical volumes according to your needs.
