Managing logical volume management (LVM) in Linux requires a good understanding of how storage components – physical volumes (PVs), volume groups (VGs), and logical volumes (LVs) interact. One of the common tasks for us as system administrators is identifying which PVs store specific LVs. This...
Physical volumes (PV) are the base "block" that you need in order to manipulate a disk using Logical Volume Manager (LVM). Now, let’s not rush ahead. What exactly is a physical volume? What in the world is LVM? In short, LVM is a type of storage virtualization that allows operators...

Logical volume names aren't case-sensitive. Ensure that no two volumes on a device have same name. For example, Volumes with names "voLUME1", "volume1" can't be protected through Azure Site Recovery. Azure Virtual Machines as Physical Failover of virtual machines with Marketplace image disks...
