Physical Volumes

A physical volume (PV) is a storage device or physical disk, such as a hard drive or SSD, used in computer systems to store data. In disk management, PVs serve as the foundational units that can be combined or divided into logical parts. They form the building blocks for creating flexible storage setups like Logical Volumes or RAID arrays. Essentially, a PV is the actual physical space where your data resides, and managing them effectively allows for better storage organization, increased flexibility, and improved data management in complex systems.
