As NTP is drift based, large time differences can prevent NTP from synchronizing,
or cause synchronization to take a long time. It can be helpful to synchronize time
manually once and to verify that the time is picked up correctly afterward. Use the
separate commands of
service ntpd stop
,
ntpdate
your IP , and
service ntpd
start
. The following example shows the sequence:
[root@ domain.node ~]# service ntpd stop
Shutting down ntpd: [ OK ]
[root@ domain.node ~]# ntpdate 9.19.0.220
14 Jan 12:06:46 ntpdate[25360]: adjust time server 9.19.0.220 offset 0.003277 sec
[root@
domain.node ~]# service ntpd start
Starting ntpd: [ OK ]
[root@ domain.node ~]#
After the time on all of the servers is synchronized, you can verify that the logs
apply to your troubleshooting situation.
