Redundancy Question: Dataset changes on backup Instance not replicating to primary

Ignition
1

Hello everyone,

I have redundancy enabled between two Ignition instances, and I have a dataset on Instance 1. When I test redundancy by shutting down Instance 1, the dataset syncs correctly to Instance 2 without any issues.

However, while running on Instance 2, I populate the dataset externally through WebDev. When I switch back to Instance 1, the data that was added while Instance 2 was active does not sync back to Instance 1.

Is this expected behavior, or did I miss something in the configuration?

Thank you!

What Ignition version 8.x.x are you running?

I don't think this is expected. But note that synchronization is not instant--it can take many seconds. It varies by module too. Tags are part of the platform--I'm not sure what the sync interval is.

How long after update was it before you told the pair to fail back to the master?
