lvm 2.02.95-r4

1. With two or more volume groups the shutdown script (/etc/init.d/lvm stop) fails due to
Code:
VGS=$($lvm_path vgs --config "${config}" -o vg_name --noheadings --nosuffix 2> /dev/null)

output for two vgs:
Code:
vg
vg0

The newline character shouldn't be there. It breaks the folowing script
Code:
#! /sbin/lvm --config 'global { locking_dir = "/run/lock/lvm" }'\nlvchange --sysinit -a ln vg
vg0\nvgchange --sysinit -a ln\n


2. I have root, usr, and home in an lvm volume group. During a shutdown procedure I get
Code:
Logical volume vg0/root contains a filesystem in use.
Logical volume vg0/usr contains a filesystem in use

What can be done to fix it? The home partition is unmounted before these errors. I'm not even sure whether root and usr are remounted in read-only.

I had the same problem. To fix it, edit /etc/init.d/lvm and replace this line:
Code:

        VGS=$($lvm_path vgs --config "${config}" -o vg_name --noheadings --nosuffix 2> /dev/null)


with
Code:

        VGS=$($lvm_path vgs --config "${config}" -o vg_name --noheadings --nosuffix | tr '\n' ' ' 2> /dev/null)


I have filed a bug https://bugs.gentoo.org/show_bug.cgi?id=451478
