I don't think that there are any core dumps. The three folders returned from
the command are empty.

alpha:~ # ls -IR /var/lib/heartbeat/cores/
hacluster  nobody  root
alpha:~ #

hb_report -f 15:27 -A -n "alpha bravo" -u root /root/problem-3

returns

Password:
alpha: WARN: could not find the log file on alpha
Password: /etc/ha.d/shellfuncs: line 211: maketempdir: command not found
alpha: WARN: sorry, can't create temoary file for find_files
/etc/ha.d/shellfuncs: line 211: maketempdir: command not found
alpha: WARN: sorry, can't create temoary file for find_files
/etc/ha.d/shellfuncs: line 211: maketempdir: command not found
/etc/ha.d/shellfuncs: line 211: maketempdir: command not found
alpha: ERROR: cannot create temporary files

I have attached the generated folder as zip file, but with a quick look, i
don't think that has something useful. Maybe its better to guide me how to
produce dump core files.

I have also tried without the -u option

Thanks

Stratos
