df, lvm and 6TB arrays oh my!



I am having a problem with df reporting the wrong disk size on a couple of 7TB arrays on a Fedora box we are using. I have an lvm group on each array of 6.36TB when I run df this is what I get:

/dev/mapper/Volume02-Volume02lv
                     2.4T   33M  2.3T   1% /mnt/arrays/array2
/dev/mapper/Volume03-Volume03lv
                     2.4T  950G  1.3T  43% /mnt/arrays/array1


When I run vg display this is what it reports:

pvdisplay  PV Name               /dev/sdd
pvdisplay  VG Name               Volume03
pvdisplay  PV Size               6.36 TB / not usable 6.00 TB
pvdisplay  Allocatable           yes (but full)
pvdisplay  PE Size (KByte)       4096
pvdisplay  Total PE              1666397
pvdisplay  Free PE               0
pvdisplay  Allocated PE          1666397
pvdisplay  PV UUID               UlaSJI-9Srm-e3AW-LdNW-g2HG-v6ZE-4yWwPw
pvdisplay
pvdisplay  --- Physical volume ---
pvdisplay  PV Name               /dev/sdc
pvdisplay  VG Name               Volume02
pvdisplay  PV Size               6.36 TB / not usable 6.00 TB
pvdisplay  Allocatable           yes (but full)
pvdisplay  PE Size (KByte)       4096
pvdisplay  Total PE              1666397
pvdisplay  Free PE               0
pvdisplay  Allocated PE          1666397
pvdisplay  PV UUID               mK7WWj-UV0p-N6Qc-zhx6-EK3J-g0CO-g65ljs


I've looked around for a lvm tool to display the correct sizes, but can't find one. Is there something I'm missing?
