Vgdisplay can tell you, in a roundabout manner.

$ vgdisplay /dev/vg00 

Multiply "Free PE" by "PE size" to get unallocated space.

To unallocated space to a logical volume (which contains a file system
which is represented by a mount point), you can use the lvextend
command. However, this is a non-trivial operation, so you may wish to
use SAM for this procedure. (SAM can also tell you how much unallocated
space you have in each volume group). As always, be SURE you have a GOOD
backup in case something goes awry. You might want to ensure you have
the latest LVM patches for your OS before proceeding, as well.
