Bug#402511: lvm-common: bogus errors during shutdown when using encrypted partition on LV

[Frans Pop]

Package: lvm-common
Version: 1.5.20
Severity: important

(Note that I personally think that this should be fixed before Etch as it 
is a recent regression and likely to cause unneeded BRs during Etch, but 
the errors are probably too harmless to warrant RC severity.)

Since very recently I'm seeing the following messages (transcribed, 
possibly not completely literal) during the last stage of shutdown:

<snip>
Stopping remaining crypto disks
Shutting down LVM Volume Groups
  /dev/dm-6: open failed, no such device or address
  /dev/dm-7: open failed, no such device or address
  Can't deactivate volume group "strider" with open LVs
Stopping early crypto disks
</snip>

I have one VG ("strider") with 6 LVs. Of those 6 LVs, two hold an 
encrypted filesystem: home and swap.

The errors for /dev/dm-[67] appeared only recently and seem bogus to me.
The "Can't deactivate volume group" message has always been there and is 
expected as I have root on an LV in VG "strider".

My dm devices are as follows:
/dev/dm-0: swap
/dev/dm-1: root
/dev/dm-2: usr
/dev/dm-3: var
/dev/dm-4: home
/dev/dm-5: srv
/dev/dm-6: home-crypt
/dev/dm-7: swap-crypt

So, it looks like the lvm init script is trying to access crypto dm 
devices that I would guess have already been disabled/removed during 
the "Stopping remaining crypto disks" phase.
