I never used LVM before so maybe I did something wrong,
but I think the lvm2 Debian package has a bug:

fz-vm:~# pvcreate /dev/sdb
  Physical volume "/dev/sdb" successfully created
fz-vm:~# vgcreate linux-vg /dev/sdb
  Volume group "linux-vg" successfully created
fz-vm:~# lvcreate -L 1M linux-vg 
  Rounding up size to full physical extent 4,00 MB
  Logical volume "lvol0" created
fz-vm:~# ls /dev/mapper/
control  linux--vg-lvol0
