That's probably that these LSB resource agents (aka init scripts)
are not exactly LSB compliant. The logs are too frightening to
read, but you can look for just what's happening with resources:
grep lrmd.*<rsc_id> /var/log/ha-log
The info:<rsc>: <action> will tell you what is about to be run:
> lrmd[11800]: 2009/04/24_08:34:42 info: rsc:dovecot_4: stop
and then just follow your resource from there.
For instance:
> lrmd[11800]: 2009/04/24_08:34:44 info: RA output:
> (dovecot_4:monitor:stderr) Usage: /etc/init.d/dovecot

This RA is missing the status action which is required. Either
find one which has it, or implement one yourself, or write an OCF
RA and contribute :)
It's very important that all your resource agents comply with
LSB/OCF standard. Take a look here:
http://www.linux-ha.org/LSBResourceAgent
I'm afraid that you can't rely on your distribution to do that
correctly. And then the best would be, given enough patience, to
test your resources by hand.
The best is to use the supplied resource agents (from heartbeat
and pacemaker) because they are more robust and written to work
with the cluster. So, perhaps you should switch from the lsb
mysql to the OCF mysql.
I hope that you got enough information to find out what's wrong
yourself ;-)
Thanks,
Dejan
