I'll download all the tutorial pdf/slides from
http://www.linux-ha.org/HeartbeatTutorials
to see where I can add more resources there instead of doing what I did.

With me it would give out all these errors which looked like it was
trying to start apache1. Could this be distro related? I installed
heartbeat 2.0.7 from Gentoo Linux.

If it works for you and not for me then something's wrong on my end.
When I try to use it I get a syntax error occuring and the mail
doesn't get sent. At first it couldn't find the actual sendmail
binary, I had to create a symlink with the same name, but that only
gave me syntax errors.

I'll try to re-produce the errors I get with the mailTo script and
post em here (or on a seperate thread with the appropriate topic)
showing what MTA I use and the config settings ...etc.

I noticed you put several scripts for using rsync to be aware of the
primary/slave status of heartbeat and invoke rsync. Thats pretty
helpful, I don't know why I couldn't find it on the website, I found
it in the /usr/share/doc/heartbeat-2.0.7  dir. Perhaps I couldn't find
it on the site, but either way that stuff is a great help.
