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.
