[ClusterLabs] Problem with a ping resource on CentOS 8

[fatcharly at gmx.de]

Hi,

I'm running a two node cluster on CentOS Linux release 8.4.2105 4.18.0-305.12.1.el8_4.x86_64 with the following pacemaker:
pacemaker-2.0.5-9.el8_4.1.x86_64
pacemaker-cluster-libs-2.0.5-9.el8_4.1.x86_64
pacemaker-libs-2.0.5-9.el8_4.1.x86_64
pacemaker-schemas-2.0.5-9.el8_4.1.noarch
pacemaker-cli-2.0.5-9.el8_4.1.x86_64

Both Nodes communicate with each other and the defined HA-IP's are working fine.
But when I add a ping-resource:

pcs resource create ping_fw ocf:pacemaker:ping dampen=5s multiplier=1000 host_list=192.168.20.1 clone

and a constraint location:

pcs constraint location HA-IP_211 rule score=-INFINITY ping_fw lt 1 or not_defined ping_fw

the cluster stops the HA-IP resources.

This is my configuration:

Cluster Name: loadbalancer

 pound31 pound32
Pacemaker Nodes:
