Linux Administration Bootcamp: Go from Beginner to Advanced - Extending Volume Group (VG) and Logical Volume (LV)

The video tutorial covers the process of extending a volume group and logical volume using LVM. It begins with identifying available disks and adding a new physical volume to the volume group. The tutorial then explains how to extend the logical volume and grow the file system using the LVL extend command with the Dash R option. Common mistakes, such as forgetting to resize the file system, are addressed, along with solutions. The video concludes by highlighting the flexibility of LVM in managing file systems across multiple storage devices.

What command is used to check the free space in a volume group?

• VG extend

• LVM disk scan

• LV extend

• VGS

Which command is used to add a new physical volume to a volume group?

• LV extend

• VG extend

• LVM disk scan

• VGS

What is the purpose of the -R option in the LV extend command?

• To rename a volume group

• To remove a logical volume

• To reduce the size of a logical volume

• To resize the file system

What does the plus syntax in the LV extend command signify?

• It specifies the exact end size

• It duplicates the logical volume

• It adds the specified space to the current size

• It removes the specified space from the current size

What happens if you forget to use the -R option when extending a logical volume?

• The physical volume will be corrupted

• The volume group will be deleted

• The file system will not resize

• The logical volume will not extend

Which tool is used to resize the file system for ext file systems?

• resize2fs

• LV extend

• VG extend

• VGS

What is the benefit of using LVM in terms of storage devices?

• It limits file system sizes to disk sizes

• It allows file systems to span multiple storage devices

• It reduces the number of physical volumes

• It simplifies the disk partitioning process
