How To Install lvm2 on CentOS 8
lvm2 is Userland logical volume management tools
Introduction
In this tutorial we learn how to install lvm2 on CentOS 8.
What is lvm2
LVM2 includes all of the support for handling read/write operations on physical volumes (hard disks, RAID-Systems, magneto optical, etc., multiple devices (MD), see mdadm(8) or even loop devices, see losetup(8)), creating volume groups (kind of virtual disks) from one or more physical volumes and creating one or more logical volumes (kind of logical partitions) in volume groups.
We can use yum or dnf to install lvm2 on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install lvm2.
Install lvm2 on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
