It is a system of managing logical volumes, or filesystems, that is much more advanced and flexible than the traditional method of partitioning a disk into one or more segments and formatting that partition with a filesystem

LVM is a logical volume manager , it comprises of Volume Group (VG) and Volume Group Comprises of Physical Volume (PV).

 

In order to create one must create partitions in disk i.e PV's  and  then join one and more PV's to become a Volume Group (VG) and then make then as a different Logical volume altogether.

LVM is Logical volume manager. In this we can create single large partition of multiple disks. For this we have follow some step like:

1. With fdisk make extended volume then change the label of that disk with LVM

2. PVcreate of that disk.

3. VGcreate of all physical disk in Volume Group

4. LVcreate of that VG

5. Now we can make file system.(Like xfs,ext4,ext3)

LVM is more flexible any time we can grow our partition without loosing any data.

LVM is a logical volume manager which is used to create logical volume and resize it as per your need on fly.

Suppose you have 3 disk of 1 TB and you need single volume bigger than individual disk then with help of LVM we can create it.

LVM means Logical Volume Manager. so Dynamic partitioning is possible, and extend the lv and decrease lv, possibility to our project,  Ubuntu there for we can create/delete/resize disk space and access able without rooting
