pacemaker will be deployed by default whether you set up 1 or more
controller nodes since Ussuri. Without pacemaker deployment is possible but
would need more changes(apart from removing pacemaker from roles_data.yaml
file), like adjusting resource_registry to use non pacemaker resources. HA
with 1 Controller works fine as we have green jobs[3][4] running with both
1 controller/3 controllers, so would recommend to look why pcsd is failing
for you and proceed with HA. But if you still want to go without pacemaker
then can try adjusting resource-registry to enable/disable pacemaker
resources

is enough to deploy without a pacemaker, you can report a bug or send a
patch to fix that with the docs link you using.
