Hello guys,
I am having problem shrinking an LVM and the physical volume afterwards.
My goal is to get to a step where I can shrink the free space with gparted and use it later for another operating system.
The volume group partition is /dev/sda2
The volume group name is VolGroup
I tried this
With Fedora 17 live cd.
I have this at the moment
And the Physical volume
Any ideas thanks in advance.

Code:
lvm vgchange -ay
//Checked for errors
e2fsck -f /dev/mapper/VolGroup-lv_home
//Resized the logical volume
resize2fs /dev/mapper/VolGroup-lv_home 150G
//Resized lvm slightly larger
lvm lvresize /dev/mapper/VolGroup-lv_home --size 151G
resize2fs /dev/mapper/VolGroup-lv_home
//Then I tried to resize the physical volume
pvresize --setphysicalvolumesize 213G /dev/sda2
//But I got an error about the extends and I tried using pmove
pvmove -v --alloc anywhere /dev/sda2
//But pvresize failed again
pvresize --setphysicalvolumesize 213G /dev/sda2
// I tried also removing and recreating the swap but it didn't work
swapoff -a
lvm lvremove /dev/mapper/VolGroup-lv_swap
lvm lvcreate --size 9.81G --name lv_swap VolGroup
