Hello, likely you can "solve" it by modifying the Redis Cluster nodes configuration in order to don't require all the slots to be covered for nodes to accept writes: cluster-require-full-coverage no However this does not solve the root cause of your issue which is that nodes from time to time detect other nodes as down. This could be done

Jan 13, 2016 · I'm looking for a quick way to reallocate those "lost" slots to the other nodes in the cluster as quickly as possible. What i'm doing right now is use redis-trib call to call the CLUSTER FORGET command on all the nodes and then call redis-trib rebalance to rebalance the lost slots. Not sure this is the correct way to do it.. CLUSTER INFO – Redis cluster_slots_assigned: Number of slots which are associated to some node (not unbound).

At the same time it is unlikely that Redis Cluster would scale to more than 1000 mater nodes because of other design tradeoffs.
