Description of problem: Host has time-drift of 19819 seconds while maximum configured value is 300 seconds Version-Release number of selected component (if applicable): Version 4.2.2.6-1.el7.centos Warning showing in UI.
Is chrony configured? Was time synchronized? Very large drifts can require manual intervention to resolve (on Linux in general), and synchronization works properly after that. I've never asked ntp/chrony engineers about this, but it is definitely intentional that intervention is required.
chrony is configured and time is synced. But still warning is showing
Please cross check time synchronization is properly configured. See https://docs.fedoraproject.org/f27/system-administrators-guide/basic-system-configuration/Configuring_the_Date_and_Time.html#sect-Configuring_the_Date_and_Time-timedatectl-NTP and https://docs.fedoraproject.org/f27/system-administrators-guide/servers/Configuring_NTP_Using_the_chrony_Suite.html as referenced in https://ovirt.org/documentation/install-guide/chap-Introduction_to_oVirt/ In comment #2 you say time is synced but you still see the warning in description "Host has time-drift of 19819 seconds while maximum configured value is 300 seconds" Can you provide a screenshot of the warning and a full sos report from that host?
Thinks for your help, I configured chrony properly. It solve the issue.
