LVM query
 

WHat is the physical volume in LVM's? Why do we need to create a physical volume first before creating LVM's? I mean, LVM's are created from physical disks, so why do we need to specify it? Didnt get it. Anybody want to help me with this?

Because you have to specify that a disk should be part of the LV. How else do you propose to do that ?

Ok...So you are saying that we specify PVs because it indicates that these PVs are used for creating LVs and not for any other purpose?...
