Issue/Introduction

This article provides information on how to manually set the NTP server for a Photon OS appliance when:
  • The NTP server previously configured is no longer valid.
  • The vCloud Availability appliance is not synchronizing with a valid NTP server set during deployment.


Environment

VMware vCloud Availability 3.0.x

Resolution

To configure an NTP server on a vCloud Availability appliance post-deployment, update the settings via command line operations on each appliance:
  1. SSH to the appliance whose NTP settings you need to update and login as the root user.
  2. Edit the timesyncd.conf file with a text editor such as vi:
vi /etc/systemd/timesyncd.conf
  1. In the [Time] section edit the NTP entry with the correct NTP server address:
[Time]
#FallbackNTP=time1.google.com time2.google.com time3.google.com time4.google.com
NTP=ntpAddress
  1. Restart the network service:
systemctl restart systemd-networkd
  1. Restart the timesync service:
systemctl restart systemd-timesyncd
  1. Verify that the time on the appliance is now synchronizing with the NTP server.
