It's this way simply because I started experimenting with the ipaddr2
resource first because it's simple and then built from there. Also, my
application specifically binds the cluster resource address (not *.*) so
it needs to be somewhere before the application actually starts, rather
than at the end, so I just left it at the beginning.

This is better, as both DRBD instances now promote to master, but the
dependent resources still do not start after the promotion. A new cib.xml
is attached. By the way, the LogicalVol resource script is just a copy of
the regular LVM once. Please don't ask why :)
