[Pacemaker] Problem with migration-threshold and fail-count if the cloned resource fails on both nodes

[Klaus Darilion]

Hi!

I have node A (armani) and node B (bulgari). I have configured a virtual
IP address and Kamailio (SIP proxy) as cloned resource running on both
nodes. If Kamailio failes two times on the node with the IP address, the
IP address is migrated.

The problem happens when Kamailio fails on both nodes at the same time,
then the cloned resource gets swapped between node A and B, and the IP
address is not migrated anymore in case of Kamailio failures.

See attached log for details of the scenario. The config is below. Is
there something wrong with my config to handle this properly or is it a bug?

I think the problem is related that the clones resource is swapped
during downtime of both Kamailio resources. Is it possible to stick a
cloned resource to a certain node?

Thanks
Klaus
