Time Synchronization Error While Adding Additional Nodes To HAA Cluster

Time synchronization error thrown while trying to add third node to HAA cluster.

Issue description:
In High-Availability-Addon, all the servers need to have a synchronized clock. If the time between servers is not in sync, the below error is thrown while adding the nodes into the cluster.

“There is a time synchronization problem between the new node and existing nodes in the cluster. You must synchronize the clocks before you can join the new node”


Resolution:
To get the clocks synchronized, run the below command with sudo permissions:

  • sudo /etc/network/if-up.d/ntpdate
More details can be found here: Synchronizing Cluster Node Clocks - Redis Enterprise .
Once the clocks are synchronized, the node can be added to the server.
