So, the commands is something like this:

pvmove -v /dev/sdb1
pvremove /dev/sdb1


For some poor soul that is as new to LVM as I am. Here is the commands I ended up using:

umount /data
e2fsck -f /dev/mapper/data-data1
resize2fs /dev/mapper/data-data1 400G
lvreduce -L 400G /dev/data/data1
pvmove -v /dev/sdb1


I did have to unmount it first. It just wouldn't proceed without that one. It then told me I had to run fsck on it too. Other than that, it seems to have worked fine.

Now to figure out a few other things.  I may be back.  o_O
