Hi Marcos,

Want to clarify one thing. If I’m using and oVirt Node based host (not EL Linux Based), does it already configured with ntp client or can I just configure any ntp client on the host ? If I just configure ntp client on the host either chronyc or ntpd, will it persist after upgrading the node ?

Thanks before.

Hi Nur,

ntpd has a 300sec limit for synchronization. If you want a more flexible NTP client, use chronyd.

If you prefer to use ntpd, you should have ntpdate as a boot client and ntpd as a runtime client.

When the server boots, the ntpdate client will sync time no matter the difference. As a boot client, it runs only once and exits. Then the ntpd service starts, and keep your server clock in sync with an external source.

On distributions like CentOS and similar, ntpdate reads the external time sources configuration from ntpd.conf. You should need booth packages and services installed and enabled:

I prefer chronyd since it does not need any extra service or procedure to keep clock synchronization.

Marcos

Hi All,

Recently I got an warning in our cluster about time drift :

Host xxxxx has time-drift of 672 seconds while maximum configured value is 300 seconds.

What should I do to address this issue ? Should I reconfigure / configure ntp client on all host ?

Thanks before.
