Just to make it clear.  LVM does not currently have multipath support.  It
is planned for inclusion into LVM or possibly a separate driver to stack
with LVM after LVM 1.0 is released.

We are currently too busy dealing with trying to get a stable LVM release
out to start adding new features now, but hopefully multipathing and other
highly requested features will be supported soon.

For now it sounds like the best option is to patch MD to support
multipathing and stack LVM on top of that.
