5.1. LVM

  1. How can you find out how many free extents are in your available volume groups?

  2. What command will tell you how much free space is left on your logical volume snapshot?

  3. What happens if your snapshot becomes full?

  4. How can you determine the origin logical volume of a snapshot?

  5. If your root paritition is a single volume group that occupies all extents on your only volume group. How can you free up space for creating other logical volumes / volume groups?

  6. If you are using LVM to back a Xen guest why does simply growing the logical volume not give your guest more disk space?

  7. If your volume groups or logical volumes are not showing up at their appropriate device mount points under /dev, what command(s) can you run to create the necessary device nodes? (Useful for working with LVM in rescue mode)
