Hi Zdenek,
sure, but I find messing with dmsetup more error prone than using an LVM 
command.

Would be an initial minimal support userful? For example, something as 
"lvchange --error vg/lvm" which will only work on simple setup, while on 
more complex ones would simply print a warning and return with exit code 
1.

Thanks.
