I still don't understand why it monitors services by default on all
nodes
when the cluster is assymetrical
Because we don't just make assumptions about what the state of the
cluster is - we verify them.
Actually, you verify what misconfigured or fake resource agents are
saying.
RAs are required to be reliable.
Garbage in, garbage out.
For what is worth, I sympathize with Pavel view (minus the cynicism).
If the cluster is asymetric, not all nodes support all resources.
Pacemaker knows that (configwise) and could avoid trying to monitor
resources in non valid nodes.
In the end, forcing the installation of fake RAs
You don't need fake RAs.
The cluster will behave just fine if the RA is missing, just not if
it's present and reports bogus status
Oops, sorry for the noise then. I don't know why I reached that
conclusion. If an absent RA does it, then it's fine.
Having an RA in a node w/o the resource makes litle sense if it does not
behave.
