The most important concept to grasp is that a Logical Volume within a Logical Volume Group can extend across multiple Physical Partitions of multiple Physical Volumes.
Tip: A Physical Volume from the point of view of your computer is a hard disc drive. In this modern age your computer could see a Storage Array (or part of a Storage Array) as one Physical Volume (though the Storage Array is actually composed of multiple discs).
i.e. When considering Physical Volumes always consider your computers view (looking out) regardless of the physical device.
The controlling software is Logical Volume Manager (LVM).
Ps: My first LVM course (albeit from Veritas) took 5 days. It's a big subject.

Hello,
I have logical volume group of 50GB, in which I have 2 logical volumes, LogVol01 and LogVol02, both are of 10GB.
If I extend LogVol01 further by 10GB, then it keeps the extended copy after logical volume 2. I want to know where it keeps this information
