Linux Administration Bootcamp: Go from Beginner to Advanced - Creating Physical Volume (PV), Volume Group (VG), and Logi

The video tutorial provides a comprehensive guide on managing Logical Volume Management (LVM) in Linux. It covers the creation of physical volumes, volume groups, and logical volumes, along with commands to identify storage devices. The tutorial also delves into advanced LVM concepts, such as logical and physical extents, and addresses common errors encountered during logical volume creation. Practical examples and command-line instructions are provided to facilitate understanding and application.

What is the first step in setting up Logical Volume Management?

• Creating a physical volume

• Creating a logical volume

• Using the LV display command

• Mounting a file system

Which command is used to scan for available storage devices for LVM?

• LVM disk SCAN

• df -h

• lsblk

• fdisk -l

What command is used to initialize a disk for use by the logical volume manager?

• LVM Initialize

• LV Create

• PV Create

• VG Create

What is the purpose of the VG Create command?

• To mount a file system

• To create a logical volume

• To create a volume group

• To create a physical volume

Which command is used to view logical volumes?

• VG Display

• LVM View

• LV Display

• PV Display

What is the significance of the /etc/fstab file?

• It lists all physical volumes

• It configures file systems to mount at boot

• It stores logical volume names

• It displays disk usage

How can you access a logical volume through the device mapper path?

• Using /etc/fstab

• Using /dev/mapper

• Using /mnt/mapper

• Using /dev/sda

What are logical extents in LVM?

• Commands for creating logical volumes

• Types of file systems

• Units of space allocation in a logical volume

• Partitions of a physical volume

What is the relationship between logical extents and physical extents?

• There is no relationship

• Logical extents map directly to physical extents

• Logical extents are larger than physical extents

• Physical extents are used to create logical extents

How can you specify the size of a logical volume using extents?

• Using the -L option

• Using the -E option

• Using the -l option

• Using the -S option
