Bug#692605: "Can't deactivate volume group" at shutdown (root filesystem on lvm)

[A. Hegerfeld]

Package: lvm2
Version: 2.02.66-5
Severity: normal


Hello there,

I'm using lvm2 inside of my virtual machines (created with kvm) and my 
setup looks like this:

# lvs
   LV   VG     Attr   LSize Origin Snap%  Move Log Copy%  Convert
   home system -wi-ao 4.66g
   root system -wi-ao 1.86g
   var  system -wi-ao 3.00g


/etc/fstab

UUID=xxx                                           /boot ext3    
noatime         0       2
/dev/mapper/system-root                   / ext4    
noatime,errors=remount-ro 0       1
/dev/mapper/system-home                /home          ext4 
noatime         0       2
/dev/mapper/system-var                    /var              ext4 
noatime         0       2


The system is running fine, but when I power off the machine I get this 
error every time just after the (successfull) unmouting of the local 
filesystems:

"Shutting down LVM Volume Groups  Can't deactivate volume group "system" 
with 1 open logical volume(s) failed!"

This error message is reproducible, I got it on several machines. The 
LVM was set up by the debian installer.

There is (as far as I can see) no loss of data, but other distributions 
don't got this problem.

Please let me know if you need any further information.

Regards,
A.
