Thank you for the quick answer.

In my /etc/ha.cf I now have:
debug		1
use_logd	false
logfacility    	daemon

I get all crit, error, warning and info messags in the syslog.

But I have still some questions.

1. Is http://www.linux-ha.org/wiki/Ha.cf#debug_-_set_debug_level
still valid concerning the changing of the debuglevel ?
I says:
..Additionally, the debug level of the system can be dynamically changed by
sending the heartbeat process SIGUSR1 and SIGUSR2 signals. SIGUSR1 raises the
debug level, and SIGUSR2 lowers it. A sample debug directive is shown below.

Which process should the signal be sent to ?
Converning the logging of RA-Agents the lrmd ?

If not how do I change the debuglevel ?
I guess there is a better option than "rcopenais restart"

2. Is there a relation between ha.cf/debug and the loglevels 
and if where can i find it ?

3. I was not able to get any message of type debug
I can force my own test messages to become visibile by using "err"

How can I get the debug-level messages i.e. from the drbd RA ?
Messages of level debug go to /etc/ha.d/shellfuncs:ha_debug

What is the appropriate logging solution and how can I configure it in
a openAIS / pacemacker setup ?

I read a lot of hints on using the logger daemon ha_logd in combination with
ha_logger. Is this still valid and how do I configure it ?
ha.cf: use_logd	true
seems not to work

Sorry for so many questions.
I can post a summary on logging when things sort out
