One design error is that you cannot "carve out" an ordinary partition
from an LVM. Once a portion of the drive is LVM, then that portion of
the drive is LVM forever until the LVM is completely gone.
This makes LVM a bad neighbor in a consulting environment where
flexibility is king: multiple systems per drive, and many of
the systems do not understand LVM.
This is a problem of partitions themselves being very inflexible.
Have said that I don't really understand why you'd ever want to do
this. "In a consulting environment" you're much more likely to
encounter some other mechanism for creating LUNs of the right size on
demand, ie. SANs.
