This behavior prevents students from starting a clean environment for subsequent labs.

Steps to reproduce:

• Complete the steps in the Section 8.2 lab.
• Run the lab finish lvm-manage command.
• Observe that not all LVM resources are cleaned up.   use lsblk command

Workaround:

Expected result:

Expected Behavior: The lab finish lvm-manage command should completely clean up all LVM-related resources and reset the environment.
