Which command is utilized to create a logical volume from partitions in physical volumes?

The command utilized to create a logical volume from partitions in physical volumes is indeed the one that performs the action of allocating space for a logical volume within a volume group. When managing Logical Volume Management (LVM) on a Linux system, logical volumes are layers over physical volumes, allowing for more flexible storage management.

The process begins with the use of physical volumes, which are typically disk partitions or entire disks that have been initialized for use with LVM. After the physical volumes are designated, they are combined into volume groups. Finally, the logical volume is created from the space available within a volume group, which is the specific function of the command in question.

The command specifically for creating a logical volume is designed to provide options such as the size of the new volume and its name, facilitating tailored storage configurations. This command directly addresses the task of constructing a logical volume from the pre-existing physical volumes that are part of the configured volume group.

Other commands mentioned, like those for initializing physical volumes or creating volume groups, serve different purposes within the overall LVM framework and do not perform the action of creating logical volumes. Thus, focusing specifically on the creation of logical volumes confirms the accuracy of the identified command.
