How do I see how much space is used in the overlay file (Fedora USB)?

[liveu...@localhost ~]$ df -h

vartmp               1013M     0 1013M   0% /var/tmp

The above command output does not seem to reflect the 2GB overlay.

Is there a way to output "just" the overlay contents? Something like 'du -hs' 
(du shows what /dev/mapper shows).

Kam,

I wrote a script to check the status of the overlay (attached).  I'll
see if I can get it included for future use.
Has anyone else had the overlay become corrupted when it gets full? I had this problem too... df -h said I had a bunch of free space so I installed lots of extra packages but then I got a error message saying "read only filesystem" I after that I couldn't run "rm" or even "ls". When I rebooted from the USB key again, it complained about logical buffer errors and I had to regenerate the overlay to fix it.
