Please post the output of #vgs and #pvs.Also you cant shrink PV you can shrink LV .
Youd first have to knowthe size you want the LV to be.Umount the drive,run fsck -y /drive,use the lvreduce command lvreduce -L newSize /dev/mapper/vg-lv-name.(you will get a warning that data will be lost if it is bigger than the shrunken size you specified,just backup first).....then run resize2fs ,resize2fs /dev/mapper/vg-lv-name .
Then remount the drive n your good.
