Comment 5 Jaroslav Kortus 2011-03-09 16:48:31 UTC
$ service cman start
$ cd /etc/corosync; cp corosync.conf.example corosync.conf
$ corosync -f ; echo $?

Mar  9 10:44:18 z4 corosync[26988]:   [MAIN  ] Another Corosync instance is already running.

Behaves as expected, maybe some error message printed would be useful.
