"ha_node_list": Unknown system parameter or bad value.
Make sure the hostname of the machine you're running HA on, has hostname set to either nodeA or nodeB. HA uses the machine hostname to identify itself in the node list.
Also, if you have the parameter ha_replica_list defined somewhere in your config file, make sure you have the same group defined for both (i.e: cubrid)
Here my /etc/hosts (on both hosts):
10.209.197.173 nodeB
10.248.233.158 nodeA
the output of hostname command should be either nodaA or nodeB. For example, if hostname output is:
[ginarrbrik@cubrid-host ~]$ hostname cubrid-host
Then you should use cubrid-host instead of nodeA or nodeB. What this means is that, instead of assigning virtual hostnames to the HA nodes, you should use the actual hostnames that those machines have. Repace nodeA with hostname of nodeA and nodeB with hostname of nodeB
