'''Certainly...'''
[[Image:lvma.png|thumb|right|800px|'''LVM''' ('''Logical Volume Manager''') is a program to manage file system size in an efficient manner.If this diagram was displayed vertically as opposed to horizontally, you could visualize building a large cake with many layers!]]
'''Think of Using LVM like "building a cake":'''
* A cake needs to rest on a '''platter'''.* In our case the ''platter '' is known as the a '''volume group'''. One default volume groupis automatically created if you enable LVM when installing a Linux OS. In this way we can support '''different volumes groups for different purposes ''' (eg. accounting dept, IT, management, etc) just like different platters would hold different types of cakes for the party!
* Just one thing: We can grow our space between other partitions in various volume groups (or platters).
 
'''Need a Bigger Cake? Add More Layers!'''
 
* We can grow a larger cake by adding more layers.
* In our case, we define and add '''physical Volumes''' to our Volume Group.
* Some think of physical volumes as partitions.
* When you want to make a bigger cake, add more layers (in our case, add more physical volumes to volume group
* The partitions should be created and formatted, then can be added as physical volumes to the volume group
