FWIW, this is precisely how Veritas Volume Manager's visual
administrator (vxva) works.  

It doesn't matter much to me how I interface with LVM and other
components, as long as there is a sane way to handle errors, and I'm
able to get all the same information vs. using ioctls.

So the general consensus seems to be to interface through the LVM tools.
That takes care of the lvm -- now the same question needs to be answered
for md and controller/disk/partition info.  This may be the wrong list.

Cheers,
Jason.
