Linux Administration Bootcamp: Go from Beginner to Advanced - Logical Volume Manager (LVM) - Layers of Abstraction

The video tutorial explains the Logical Volume Manager (LVM) and its layers of abstraction, including physical volumes, volume groups, and logical volumes. It describes how LVM introduces flexibility in managing storage by allowing different types of storage devices to be used as physical volumes, which are then grouped into volume groups. Logical volumes are created from these groups, enabling dynamic resizing of storage space. The tutorial highlights the benefits of LVM in managing storage efficiently and performing data migrations.

What is the primary role of a physical volume in LVM?

• To act as a file system

• To serve as a block storage device

• To manage network connections

• To provide user authentication

How can you increase the size of a volume group?

• By compressing existing data

• By deleting unused files

• By adding more physical volumes

• By adding more logical volumes

What is a key feature of a volume group in LVM?

• It can only contain one type of storage

• It cannot be expanded

• It is used for network management

• It acts as a pool of storage

What is the main advantage of using logical volumes over traditional disk partitions?

• They require less maintenance

• They are faster to access

• They allow for dynamic resizing

• They are more secure

What must be available in a volume group to extend a logical volume?

• Additional network bandwidth

• Free space

• More logical volumes

• Extra user permissions
