Did you tried to make this lv non-available firts (lvchange -a n)? The lsof command you used may not work this way. Try also something like this:
lsof /dev/mapper/domu-atta
or use:
fuser -vm /dev/domu/atta

Hi stefan:
man fuser say: m mmap'ed file or shared library
I think it shouldn't been a valid option in my scene because fuser -vm output very much process ,but I can remove the device still.
