Troubleshooting SYNC replica not being confirmed

If you’re connecting to the cluster and encounter the error message “At least one SYNC replica has not confirmed…” when writing to the main instance, several issues could be causing this. Below are the possible reasons and how to resolve them:

1. Network isn’t correctly configured between MAIN and REPLICAs -> Check if hostnames/IPs can be reached.
2. Storage on replica isn’t clean -> If you used your replica instances before connecting them in the cluster, MAIN won’t be able to successfully register replica instance. Delete data directory of data instances and try to reconnect the cluster again.
