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”

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
