Directly from vgcreate(8) (lvm2 tools, version 1.95.15-1 (Debian Sid)):

   To limit kernel memory usage,  there  is  a  limit  of  65536 physical
   extents  (PE) per logical volume, so the PE size determines the maximum
   logical volume size.  The default PE size of 4MB limits a single logi-
   cal  volume to 256GB (see the -s option to raise that limit). There is
   also (as of Linux 2.4) a kernel limitation of 2TB per block device.

As far as I remember, this limit is also there in LVM1.

Hope it helps.
