I think pacemaker is unable to check default source address on node
which are not currently owning the IP addresses, which is expected.
However Default-Public-IPv4-Is-Default-Src is +INF colocated with
public IP addresses, so I do not understand why such errors are
generated on inactive nodes.
This is the probe-action, which will check whether the resource has
the expected status (e.g. stopped for nodes where it's not running).
You can either setup another IP on the same network on the interface
to avoid these errors, or setting cidr_netmask and interface might help.
IPsrcaddr doesnt advertise the interface parameter, so you probably
have to do e.g. "pcs resource update -f
Default-Public-IPv4-Is-Default-Src nic=<interface>" to set it anyways,
so findif will be able to use it.
