[linux-lvm] pvmove unable to move extents to multiple smaller pvs

Some more information that may be of use:
kernel 2.4.26 (vanilla) on gentoo on a P4 HT and SMP is enabled
lvm 2.00.08

It seems that everytime I do a "pvmove" it would be hard to always go to 
a contiguous pv the same size or bigger.  This is why I wonder if I'm 
doing something wrong.

Thanks again [to anyone out there],
Scott Serr
