I'll have a look at the HOWTO, it's hard to keep eveything straight.
The configure script has the working commands in it.

The HOWTO has a detailed section on mon, since I did it myself. I don't
have any docs on HA and I refer people to the ultramonkey pages. I go to
great pains to not advocate one method or another. That's hardly advising
people to do mon.

The HOWTO says there are problems with mon. Some of the versions of mon
just don't work at all for me. The HOWTO lists the versions that I got to
work.

WHat you've got is free and was done in people's spare time.
The configure script will setup mon and the LVS for you and hasn't failed
on me in over a year and I probably run it several times a day. I've
demostrated mon failover by pulling network cables for a room full of
people several times at 10mins notice. Other people who don't know the
configure script, as well as I do, have trouble with it. I'm trying to fix
it so they have less trouble. I have to wait for people reporting
problems.
If you want an automatic fail-proof commercial grade install, then expect
a automatic commercial fail-proof grade price. There are many people on
this mailing list who could do this for you. Just post your specs and
ask people to discuss it with you offline.
