FYI, this is normal. It just means the lrmd hasn't been asked to do
anything with this resource before, so it's not found in the lrmd's memory.

At any given time, one node in the cluster has been elected DC. The DC
schedules all actions. So, the logs on the DC (not this node) will have
the explanation for why there was no probe, and why there was a stop.

The combination of 'not configured' and call=999999999 has only one
possible source: the crmd could not register the resource with the lrmd.

Usually this means the resource definition in the CIB is inherently
invalid. However, it can also be reported when there is any kind of
error in the communication between the two daemons: the connection
dropped, the machine was out of memory, the communication timed out
(e.g. due to high load), etc.

The "Added 'dbx_head_head' to the rsc list" message means that the lrmd
did receive and complete the register request, so the problem occurred
sometime between there and crmd getting the result back.

This explains why you don't see a probe being executed. The crmd
couldn't register the resource with the lrmd, so it immediately failed
the probe on its side.

The root cause is a mystery at this point, but hopefully that gives you
some hints as to what to look for. Check the logs on the DC, and check
the host's system logs for any signs of trouble at that time.
