Hi!
Want to install Oracle Clusterware 12.1.0.2 on Oracle linux 7.1 x64. During installation all was fine except last step - Oracle Cluster verification utility failed with INS-20802.
In log file i found:
INFO: Starting Clock synchronization checks using Network Time Protocol(NTP)...
INFO: NTP configuration file "/etc/ntp.conf" existence check passed
INFO: PRVF-7590 : "ntpd" is not running on node "pdc-sap-ascs1"
INFO: PRVF-7590 : "ntpd" is not running on node "pdc-sap-ascs0"
INFO: PRVG-1024 : The NTP Daemon or Service was not running on any of the cluster nodes.
INFO: PRVF-5415 : Check to see if NTP daemon or service is running failed
INFO: Clock synchronization check using Network Time Protocol(NTP) failed
INFO: PRVF-9652 : Cluster Time Synchronization Services check failed
also in xml file i fond:
<ELEMENT>Network Time Protocol (NTP)</ELEMENT>
<DESC>This task verifies cluster time synchronization on clusters that use Network Time Protocol (NTP).</DESC>

<MSG_TXT>PRVF-5507 : NTP daemon or service is not running on any node but NTP configuration file exists on the following node(s):
pdc-sap-ascs1,pdc-sap-ascs0</MSG_TXT>
<CAUSE> The configuration file was found on at least one node though no NTP daemon or service was running.</CAUSE>
<ACTION> If you plan to use CTSS for time synchronization then NTP configuration must be uninstalled on all nodes of the cluster.</ACTION>
</ERROR_DESC>
But at all nodes ntpd is running:
[root@pdc-sap-ascs0 ~]# ps ax|grep ntpd
2214 pts/0 S+ 0:00 grep --color=auto ntpd
19438 ? Ss 0:05 /usr/sbin/ntpd -u ntp:ntp -g -x
[root@pdc-sap-ascs1 ~]# ps ax|grep ntpd
11492 pts/0 S+ 0:00 grep --color=auto ntpd
19090 ? Ss 0:05 /usr/sbin/ntpd -u ntp:ntp -g -x
So, why postinstall checker failed to find running ntpd?
Such situation was before I started installation, but that time I skipped the warning.
