[gentoo-user] suspend2 with lvm

[Shaochun Wang]

Hi Everyone:

I use suspend2 and lvm at the same time. I use a lvm partition
(/dev/vg/swap) as my suspend target by setting
resume2=swap:/dev/vg/swap.

I order to use make it work, I use initramfs. It works properly except
that I get the following message when I shut down the computer:

	Unable to shutdown: /dev/vg/swap

After some analyzing, I know it happens because the open count of
/dev/vg/swap is 2 when the script /lib/rcscripts/addons/lvm-stop.sh is
executed.

Maybe this is the problem of baselayout or my initramfs. 
How can I resolve it?

My initramfs is at
http://lcs.ios.ac.cn/~scwang/docs/initramfs_data.cpio.gz

The following is my some information of my system:

I assume this is when you fully shutdown the system (shutdown -h now
or similar)?

If so, my first instinct is to simply ignore it, since it is totally
harmless.  But I suppose you could put this in your
/etc/conf.d/local.stop:

echo 0x0000 >/proc/suspend2/resume2

I'm not currently using suspend2, but IIRC, this should clear the
reference that suspend2 has on the device.
