Hi,
Changing the cluster version reloads the rgmanager configuration, but it restarts my custom resources despite the fact that they were "started" (in clustat).
Just changing the cluster.conf version, not doing anything to my custom resource makes this happen.
In the log I get the message :
<info> Stopping changed resources
<info> Restarting changed resources
<info> Starting changed resources
which may be generic messages and then I see my resources being stopped and restarted.
Sometimes, I also can notice that my service after being stopped, I have a monitor action that is triggered that fails (normal service is stopped) and that disables (status failed) completely the service.
I'm running Rhel 5.3 (I saw the post about VM's on RHel 5.2 which seems to be similar).
I've tried to run rgmanager in debug (clurgmgrd -d) mode but it seems to get stuck
Any idea on what I may be missing ?

doesn't record for example file mtimes and run stat() to see if metadata
changed. Doing this wouldn't work anyway, as some resources have
external metadata.
You can run:

rg_test rules | grep ^Agent
There's no way currently to have rgmanager log specifically which agent
it loaded at run-time.
Not immediately; we still have a bit to go:

* need configuration file format conversion utility
* need basic "work-alike" tools. Ex: clustat.
* need to do a bit of work on rgmanager agents so they work
on pacemaker - the standard by which rgmanager+pacemaker
operate was inadequate and the two programs have diverged
in slightly incompatible ways
