Some of the terms which you need to understand while using LVM: Physical Volume (PV): Consists of Raw disks or RAID arrays or other storage devices. Volume Group (VG): Combines the physical volumes into storage groups. Logical Volume (LV): VG's are divided into LV's and are mounted as partition Centos 7 release made major changes on snapshots to make it more perfect. With Logical Volume snapshots, you are able to freeze a current state of any of your logical volumes. It is a special type of volume that presents all the data that was in the volume at the time the snapshot was created. This means that you can very easily create a backup and once needed rollback to an original logical.
