LVM question


The documentation for LVM is not really clear on this so I maybe someone here knows..

I have a server that has multiple partitions in a VG called 'storage' if I add another lv (logical volume) to that volume group what will happen?

To phrase the question better, will LVM allow me to add logical volumes to a volume group without destroying the data on the rest of the logical volumes within that volume group? if so how do I do that?

Yes - if the vg has sufficient space.
There is a good how-to on tldp.org. It may look dated, but it's still good.

assuming you care about your data: might I suggest that you test vg creation in a virtual environment before trying it on your physical?
