[linux-lvm] Unable to add new drive to LV

[Paul Waldo]

Hi all,

I'm trying to add a shiny new drive (/dev/hdd) to an existing Logical Volume 
to no avail.  The HOWTO says I should be able to do this.  Googling indicates 
that others have had this problem, but tells of no recorded resolution.   I 
was hoping someone could point me to solution.  Info below.  Thanks in 
advance!
