This is how I created a 2.7TB filesystem on an Apple X-Serve RAID:
pvdisplay is used to get the number of Physical Extents for use in the 
lvcreate command.

[root at server ~]# pvcreate /dev/sdc
  Physical volume "/dev/sdc" successfully created
[root at server ~]# vgcreate AppleVolumeGroup00 /dev/sdc
  Volume group "AppleVolumeGroup00" successfully created
[root at server ~]# pvdisplay
  --- Physical volume ---
  PV Name               /dev/sdc
  VG Name               AppleVolumeGroup00
  PV Size               2.73 TB / not usable 0
  Allocatable           yes
  PE Size (KByte)       4096
  Total PE              715401
  Free PE               715401
  Allocated PE          0
  PV UUID               eAbghb-luKx-Esod-FURR-aifi-Hb3d-EFGC2o

[root at server ~]# lvcreate --name Backup00 --extents 715401 AppleVolumeGroup00
  Logical volume "FrnBackup00" created
[root at server ~]# mke2fs -j /dev/AppleVolumeGroup00/FrnBackup00
