Issue/Introduction

After performing "APPLY CONFIGURATION" in TKGI Management Console, "Deploy ops-manager" phase failed with the following error.

error validating Ops Manager ntp: Command error output: ntp servers provided invalid , error: exit status 1

Environment

TKGI Management Console

Cause

NTP validation check failed when reach column includes "0"

Example output in ops-manager VM.

# cat /home/ubuntu/ntpcheck.log
     remote     refid             st t when poll reach   delay   offset  jitter
==============================================================================
 <NTP-SERVER-1> <Reference NTP>   16 u  620   64    0    0.000   +0.000   0.000
 <NTP-SERVER-2> <Reference NTP>   3  u   61   64    1   26.835   +0.536   0.000

Resolution

1. Review if the NTP server is valid

TKGI Management Console --> TKGI Configuration --> 2. Networking --> NTP Server

 

2. Fix the NTP server configuration in ops-manager

The NTP servers are correct but not synchronized with the Ops Manager. Manually correct the synchronization.

ssh ubuntu@${OPSMAN_IPADDR}

# If there is a significant difference in the local time, adjust it manually
sudo systemctl stop ntp
sudo systemctl status ntp
sudo ntpd -q
sudo systemctl start ntp

# Check
sudo systemctl status ntp
sudo ntpq -np
