Linux Administration Bootcamp: Go from Beginner to Advanced - Migrating Data from One Storage Device to Another

The video tutorial explains how to migrate data between storage devices using LVM. It covers initializing a new disk, adding it to a volume group, and using the PV move command to transfer data without downtime. The tutorial also discusses verifying the migration and removing the old disk from the volume group. Additionally, it highlights the flexibility of using different-sized storage devices within the same volume group.

What is the first step in preparing a new disk for data migration in LVM?

• Use the PV move command

• Run the VG extend command

• Remove the old disk with PV remove

• Initialize the disk with PV create

Which command is used to move data from one physical volume to another in LVM?

• VG extend

• PV create

• PV move

• VG reduce

During the data migration process, what happens to the logical volumes and file systems?

• They are taken offline

• They remain online and available

• They are deleted

• They are duplicated

After data migration, how can you confirm that the old disk is no longer in use?

• Run the VG extend command

• Reboot the system

• Use the PV move command again

• Check the allocated extents with PV display

What flexibility does LVM offer regarding the sizes of physical volumes in a volume group?

• Sizes must be multiples of 10GB

• All physical volumes must be the same size

• Only two sizes are allowed

• Physical volumes can be of different sizes
