We recommend that you verify NTP synchronization before proceeding further. Some nodes, particularly those that reference the controller node, can take several minutes to synchronize.

Run this command on the controller node:

# chronyc sources

  210 Number of sources = 2
  MS Name/IP address         Stratum Poll Reach LastRx Last sample
  ===============================================================================
  ^- 192.0.2.11                    2   7    12   137  -2814us[-3000us] +/-   43ms
  ^* 192.0.2.12                    2   6   177    46    +17us[  -23us] +/-   68ms

Contents in the Name/IP address column should indicate the hostname or IP address of one or more NTP servers. Contents in the MS column should indicate * for the server to which the NTP service is currently synchronized.

Run the same command on all other nodes:

# chronyc sources

  210 Number of sources = 1
  MS Name/IP address         Stratum Poll Reach LastRx Last sample
  ===============================================================================
  ^* controller                    3    9   377   421    +15us[  -87us] +/-   15ms

Contents in the Name/IP address column should indicate the hostname of the controller node.
