Verify operation
~~~~~~~~~~~~~~~~
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:
.. code-block:: console
# 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
.. end
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:
.. code-block:: console
# 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
.. end
Contents in the *Name/IP address* column should indicate the hostname of the
controller node.
