Introduction to LVM thin provisioning
LVM (Logical Volume Manager) is a technology which allow us to create a layer of abstraction over physical storage devices, and implement flexible partitioning schemes where logical volumes are easier to shrink, enlarge or remove than classical “bare” partitions. While LVM “thick” provisioning requires the allocation of a fixed amount of storage space to a LVM logical volume at creation time, by using “thin” provisioning, storage is allocated only when needed.
