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.. why redis-cluster use 16384 slots? - 爱程序网 This means they contain the slots configuration for a node, in raw form, that uses 2k of space with16k slots, but would use a prohibitive 8k of space using 65k slots. At the same time it is unlikely that Redis Cluster would scale to more than 1000 mater nodes because of other design tradeoffs. Re: [redis-db] [ERR] ... CLUSTERDOWN but the cluster isn't ... 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.

There are 16384 hash slots in Redis Cluster, and to compute what is the hash slot of a given key, we simply take the CRC16 of the key modulo 16384. How to resume hash slots of a particular node in redis ... However, if I am using redis cluster as a cache, I would like these hash slots to be served by some other node.

Redis assigns keys to nodes by calculating the hash slot like this: CRC16(key) mod 16384 Reddie: Cluster slots
