Time Synchronization Error While Adding Additional Nodes To HAA Cluster

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

In High-Availability-Addon, it is important for all the servers to have a synchronized clock. If the time between servers are not in sync, below error is thrown while adding the nodes into 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:
In order to get the clocks synchronized, run below command with sudo permissions:

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