PRVF-5507 : NTP daemon or service is not running on any node but NTP configuration file exists on the following node(s): node1,node2 – Cause: The configuration file was found on at least one node though no NTP daemon or service was running.
Cause:
While installation of cluster, ntpd is useful to synchronize the time with the cluster

Action:
If it is non production system, then we can rely on CTSS cluster service to synchronize the time with cluster. Hence to overcome this error, as workaround – ntpd can be disable unless it is a critical system. Otherwise ntpd needs to be configured
[root@x3dbzx69 u01]# service ntpd stop
Shutting down ntpd: [FAILED]
[root@x3dbzx69 u01]# chkconfig ntpd off
[root@x3dbzx69 u01]# mv /etc/ntp /etc/ntp.bkp
[root@x3dbzx69 u01]# mv /etc/ntp.conf /etc/ntp.conf.bkp
