How does LVM work in Linux?

It works by chunking the physical volumes (PVs) into physical extents (PEs). The PEs are mapped onto logical extents (LEs) which are then pooled into volume groups (VGs). These groups are linked together into logical volumes (LVs) that act as virtual disk partitions and that can be managed as such by using LVM.

What are the advantages of LVM?

Unlike classical approach where file system is created in fixed partition, LVM creates file system in flexible logical volume. Since logical volumes are flexible in nature, we can add additional disk space in a volume which is filled up or we can shrink a volume which is merely used and has a plenty of free space.
