LVM questions

[smithisize]

Ok, so I have LVM completely set up and configured. But I have a logistical question. I have two physical discs comprising my logical volume, totaling 150gb. I also set the size of the LVM to 150gb. So, my question is, if I set the logical volume size larger than that of the physical drives, what happens?

In this case, the logical volume spans across the physical drives.

The "Volume Group" creates a pseudo drive and the "Logical volume" is like a partition in the pseudo drive. This is what the main frames have been doing for decades and that is why the term "volume" is present. The "logical volume" does not have to be in a single block within the "Volume Group". When a "logical volume" is extended, it can just add another section from the unused space in the "Volume Group".
