What is the output of
fdisk -l
vgdisplay -v
and
df -h
Looking at your current output, I don't see that you have any free physical extents, except on sda1 which only has 1 extent free (32MB). Typically, sda1 is /boot, and is a standard ext partition (not a PV)

I would need to see your storage layout in better detail to give you any advice as to how to provision storage for /root and /var
The commands I referenced should give me a better idea as to what you may need to do.
