Time synchronization

You might see issues with time synchronization in your grid.

Inaccurate NTP servers

If you encounter time synchronization problems, verify that you have specified at least four external NTP sources, each providing a Stratum 3 or better reference, and that all external NTP sources are operating normally and are accessible by your StorageGRID Webscale nodes.

Note that you should not use Windows Time Service on a version of Windows earlier than Windows Server 2016 as an external NTP source. Versions earlier than Windows Server 2016 are not sufficiently accurate and are not supported by Microsoft for use in high-accuracy environments. See Windows Server reference documentation for more information on Windows Time Service limitations. https://technet.microsoft.com/en-us/windows-server-docs/identity/ad-ds/get-started/windows-time-service/windows-time-service
