Unable to reduce the size of volume group?

My volume group of size 200 gb.

out of which only 100 gb is used by 2 logical volumes /dev/vg00/lvol0 and /dev/vg00/lvol0 respectively (both are 50 gb each).

Whenever i use vgreduce command to reduce the size of volume group i get below error.

Code:

# vgreduce vg00 -a
  Physical volume "/dev/xvdb5" still in use

How can i reduce the volume group size to free up 100 gb?

Code:

# lvdisplay
  --- Logical volume ---
  LV Name                /dev/vg00/lvol0
