Extending an LVM Volume to Its Max
Unless a System Administrator states a partitioning or LVM layout (which the junior level folks may not be able to do) I use a default layout in their Kickstarts. It does a basic layout using about 20G and leaving the rest unallocated in a single Volume Group in LVM. So what’s a common question I get? You guessed it, how do you resize a volume. How do you resize it to take up the rest of the available space?
Usually its the volume mounted at / that folks want to enlarge.

The easy part to remember is how to do an on-line resize of that file system.
