Never run LVM2 utilities while you have LVs active under LVM1.
Never run LVM1 tools while you have LVs active under LVM2.

i.e. Never mix use of the two, and always vgchange -an before switching 
between LVM1 and LVM2.
Also, if switching back from LVM2 to LVM1 you must first reset the 
LVM1 driver with lvmchange -R followed by vgscan -f.
