I could add the Zabbix service to the cluster with the following command;
pcs resource create p_zabbix ocf:heartbeat:zabbixserver params
binary="/usr/local/sbin/zabbix_server"
pid="/usr/local/etc/log_zabbix/zabbix_server.pid" op monitor interval="10s"
timeout="20s" op stop interval="0" timeout="20s" meta target-role="Started"
The project is going, I will now adjust the application and go to the GSF2
for active / active cluster.
