How do I see how much space is used in the overlay file (Fedora USB)? [liveuser@localhost ~]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/live-rw 3.0G 2.2G 771M 75% / tmpfs 1013M 288K 1013M 1% /dev/shm /dev/sdb1 15G 8.3G 6.8G 55% /mnt/live varcacheyum 1013M 0 1013M 0% /var/cache/yum /tmp 1013M 104K 1013M 1% /tmp 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).

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.
