[Pacemaker] crmd exits and restarts after failback

Hi,

I have set up a pacemaker cluster on Ubuntu 10.04 LTS Server.
Further I wrote an multistate OCF RA for the Rsyslog service. This RA passes
all tests that are run by the ocf-tester tool.

Now the problem:
When I firstly start the msSyslog resource it promotes on node1 and is fully
functional. After that I set node1 to standby. The other node (node2) takes
the master role. This behaviour is just as expected. Then I set node1 to
online again to test if the failback works. There the error occurs: the crmd
exits and starts again. These actions occur in an endless loop and I can
just reboot both nodes several times to come in a functional state again.
I attached a summary of the log file so that you can see what's happening
exactly. In addition I attached the Rsyslog RA and the cluster config.

Maybe someone has a clue why the crmd is restarting all the time after the
failback. I think that there is an error in the Rsyslog RA because the
cluster works fine when I stop the Rsyslog resource manually.

Simon Jansen
