Hi,

Does this thread do an adequate job of documenting the process of 
removing a PV from an L?
     http://ubuntuforums.org/showthread.php?t=449711

The problem is that sdb2 is the largest PV in my LV.

Is there a simpler way?

# pvscan

As you can see, there's a whole lot of extra space on the LV.

Thanks.
