    Getting Volume Group Info

    In environments with machines containing many volume groups and filesystems, we want easy ways of manipulating that information. There's always a need to know to know which filesystem is in which volume group. If you want to grow the size of a filesystem, you are going to want to know which volume group it is in so that you will be able to check if that volume group has free space available in it or not.
