How to shrink a LVM partition

[vitaminx <vitaminx@callistix.net>]

Hello,

I'd like to shrink a LVM partition on my harddisk. My current setup is
like that:


    Name        Flags      Part Type  FS Type          [Label]
Size (MB)

------------------------------------------------------------------------------
    sda1        Boot        Primary   Linux ext3       [boot]
246,76
    sda5                    Logical   Linux LVM
159792,52


sda5 is ~160 GB.


I already shrinked the VG:

# vgdisplay | grep Size
  VG Size               140,00 GiB
  PE Size               4,00 MiB
  Alloc PE / Size       4197 / 16,39 GiB
  Free  PE / Size       31642 / 123,60 GiB


So what I want is to reduce the LVM partition sda5 to 140 GB as well.

Is it possible without any data loss?


Thanks & regards,
