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

^* 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 *S* 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
