Note that this command **does not work +for masters if they hold one or more keys**, in that case to completely reset a +master node keys must be removed first, e.g. by using `FLUSHALL` first, and then +`CLUSTER RESET`. + +Effects on the node: + +1. All the other nodes in the cluster are forgotten. +2. All the assigned / open slots are reset, so the slots-to-nodes mapping is + totally cleared. +3. If the node is a replica it is turned into an (empty) master. Its dataset is + flushed, so at the end the node will be an empty master. +4. **Hard reset only**: a new Node ID is generated. +5. **Hard reset only**: `currentEpoch` and `configEpoch` vars are set to 0. +6. The new configuration is persisted on disk in the node cluster configuration + file. + +This command is mainly useful to re-provision a Redis Cluster node in order to +be used in the context of a new, different cluster. The command is also +extensively used by the Redis Cluster testing framework in order to reset the +state of the cluster every time a new test unit is executed. + +If no reset type is specified, the default is **soft**. + +@return + +@simple-string-reply: `OK` if the command was successful. Otherwise an error is +returned. -- cgit v1.2.3
