I recently did a fresh install of Fedora19 over Fedora17 on a system that is dual booted with Win7. Everything is working properly but what really confuses me is that lvm and df are inconsistent with showing the amount of free space there is on the extended partition. lvm reports 18.90GB free while df reports 31GB. When I view system-config-lvm, the swap partition is somehow in the middle of the volume group? Is the swap partition causing the inconsistency? If so, would it be a good idea to delete the swap partition and use a swap file instead?

df -h output:
