PRVF-5436 : The NTP daemon running on one or more nodes lacks the slewing option "-x"

When I am Executing Cluster Verification utility I am facing below Error :


[oracle@dev147 bin]$ ./cluvfy stage -pre crsinst -n dev133,dev147 -fixup -verbose

Checking NTP daemon command line for slewing option "-x"
Check: NTP daemon command line
  Node Name                             Slewing Option Set?
  ------------------------------------  ------------------------
  dev147                                   no
  dev133                                   no
Result:
NTP daemon slewing option check failed on some nodes
PRVF-5436 : The NTP daemon running on one or more nodes lacks the slewing option "-x"
Result: Clock synchronization check using Network Time Protocol(NTP) failed

The solution was to re-configure the NTP server as follows:

Edit the /etc/sysconfig/ntpd configuration file and add the -x 

example :
Old Value

OPTIONS="-u ntp:ntp -p /var/run/ntpd.pid"

New Value :

OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid"

The NTP server was then restarted as follows:

service ntpd restart


Result :

Starting Clock synchronization checks using Network Time Protocol(NTP)...

NTP Configuration file check started...
The NTP configuration file "/etc/ntp.conf" is available on all nodes
NTP Configuration file check passed

  dev133                                yes
