[linux-lvm] 2TB partition size limit in LVM2? Or ReiserFS?

I've used LVM2 in the past, and have followed the steps in the LVM HOWTO, but have run into problems trying to grow a reiser3 filesystem. The filesystem has worked fine for several months, but now I'm trying to make it larger...
I've added a pv and am showing free PE's:
--- Volume group ---
VG Name vg
Metadata Areas 2
Metadata Sequence No 11
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 1
Open LV 1
Max PV 0
Cur PV 2
Act PV 2
VG Size 2.44 TB
PE Size 4.00 MB
Total PE 639113
Alloc PE / Size 320597 / 1.22 TB
Free PE / Size 318516 / 1.22 TB
VG UUID bADYIh-N4mr-LTJS-5h6b-izph-pgpT-exoOTh
....and I can plug those free PE's into lvextend:
lvextend -l+318516 /dev/vg/lv
> Extending logical volume lv to 2.44 TB
> Logical volume lv successfully resized
....but resize_reiserfs gives errors:
> resize_reiserfs 3.6.19 (2003 www.namesys.com)
> bread: Cannot read the block (328029183): (Invalid argument).
> reiserfs_open: Your partition is not big enough to contain the
> filesystem of (328029183) blocks as was specified in the found super block.
Nothing is written to syslog when resize_reiserfs runs. How can I tell if this is a LVM2 error providing wrong sizes... or if it's reiserfs tools having the problems? If I lvreduce things to the initial size I can remount things OK, and reiserfsck reports no errors.
This is an AMD2700+ system running 18.104.22.168, a ReiserFS3 3.6 filesystem w/ v3.6.19 reiserfsprogs, and LVM2 v2.01.09 utils
Any suggestions are appreciated.
