XFS.. HERE I COME!!!!!!! The LUKS partition was indeed the culprit. The LUKS partition was not accurately representing the size of the underlying logical volume (when over 2gb) automatically; in order to handle partitions over 2gb it is necessary to explicitly specify the desired size of the LUKS partition (size<lv) to the LUKS partition itself (via the LUKS "resize" command). It seems that mkfs.xfs relies on an accurate LUKS size in order to work on logical volumes greater than or equal to 2gb. I updated this info on the LUKS wiki and other forums...
So just to recap.... if you are getting the error:
"mkfs.xfs: libxfs_device_zero write failed: Input/output error"
make sure that you have resized the underlying LUKS partition to the desired size.
Thanks for the help; much appreciated.

mkfs.xfs actually does writes out at the end of the device and verifies
them; I'm not sure ext3 is doing the same. You may find yourself in
trouble on ext3 post-mkfs (or you may not...) I seem to recall that xfs
has shaken out similar problems on other block devices for this reason.
I'd do some simple device-level read/write tests around 2GB just for
fun, see how it goes.
