NOREPLICAS: NOREPLICAS Not enough good replicas to write

Redis

What does it mean?

Because of the min-replicas-to-write setting, writes are rejected since there are not enough healthy replicas. Redis blocks writes for data safety.

Why does it happen?

Not enough replicas connected/up to date, replica crashes, replication lag exceeding the min-replicas-max-lag limit, network problems, or missing replicas after a failover.

How to fix it

Check replica status: INFO replication. Bring down replicas back up and reduce replication lag. Fix network connectivity. Review the min-replicas-to-write / min-replicas-max-lag settings for your environment (the balance between durability and availability). Provide enough replicas.
