[linux-lvm] shrink VG and PV

[Dael Elcar]

My system is archlinux i386. lvm version 2.02.62(1) (2010-03-09)
I'd like to shrink a partition with lvm on it. Can this be done? In order to
shrink it I need to reduce the size of the PV, right? I have successfully
removed an LV (from the end on the VG) and there is no mention of it with
lvdisplay or in the file i get with vgcfgbackup. I think the next step is to
reduce the size of the VG and remove the now unallocated 3884 PEs from it. I
can't find a command for that. I have tried pvresize. How do I solve the
problem with "metadata areas"? vgdisplay says VG Status is "resizable".

pvresize /dev/sda2 --test --setphysicalvolumesize 49256M
Test mode: Metadata will NOT be updated.
/dev/sda2: too many metadata areas for pvresize
0 physical volume(s) resized / 1 physical volume(s) not resized
