A Logical Volume is a storage unit in a computer system that allows for flexible management of disk space. It is part of a larger system called Logical Volume Management (LVM), which enables users to create, resize, and delete volumes without needing to reformat the underlying physical disks. This flexibility helps optimize storage use and can improve system performance. Logical volumes can span multiple physical disks, making it easier to manage large amounts of data. They can also be easily adjusted as storage needs change, allowing for efficient allocation of resources. This adaptability is particularly useful in environments where data requirements fluctuate frequently.
