Welcome to the wonders of LVM. |

|

You turn a drive / partition into something that LVM can use. Then you |
9 |
add said drive to an existing Volume Group. Then you tell LVM to vacate |
10 |
the old physical drive. Then you remove the old physical drive from the |
11 |
Volume Group. Finally you should clean the LVM metadata from the drive, |
12 |
but that's not strictly required. |

Similar could be said about upgrading / trading bookshelves too. |

Figuring out what you want to do can be more challenging than figuring |
29 |
out how to do it. |
