I'm using CentOS, and its native file browser. Under the right selection, that browser shows the total free space available (status bar, bottom-left)to the system over all partitions

I just had a self-administered crash course in LVM, so I know what a volume group and a logical volume is. The point behind LVM is to make all disk space seem contiguous to the OS.
What I don't understand is why adding the new HDD (with a single partition) to a new Logical Volume within a new volume group, does not produce the same result as adding the drive to an existing Logical volume in an existing volume group?
