Start new redis instance using the redis-server. It is not part of any cluster as of now. Add new node in the existing cluster ./redis-trib.rb add-node NewNodeIP:PORT AnyMasterNodeOfClusterIP:PORT; Newly added master node does not cover any slots currently. You can check the same using redis-cli -h AnyMasterNodeOfClusterIP -p PORT cluster nodes redis-cluster.conf · GitHub # By default Redis Cluster nodes stop accepting queries if they detect there # is at least an hash slot uncovered (no available node is serving it). # This way if the cluster is partially down (for example a range of hash slots # are no longer covered) all the cluster becomes, eventually, unavailable. Scaling a High-traffic Rate Limiting Stack With Redis Cluster 5461-10922 means that this node handles the range of slots starting at 5461 and ending at 10922. `MOVED` redirection. If a node in a Redis Cluster receives a command for a key in a slot that it doesn’t handle, it makes no attempt to forward that command elsewhere. Instead, the client is told to try again somewhere else. golang redis cluster redis cluster安装部署 - Redis - 服务器之家

The command is suitable to be used by Redis Cluster client libraries implementations in order to retrieve (or update when a redirection is received) the map associating cluster hash slots with actual nodes...
In the Redis cluster implementation, a minimal three node Redis cluster assigns these hash slots with the first master having hash slots 0 to 5500, the second master node being assigned hash slots 5501 to 11,000, and the third master having the remainder of 11,001 to 16,384 hash slots.
