CLUSTER RESET [HARD|SOFT]
Reset a Redis Cluster node, in a more or less drastic way depending on the reset type, that can be hard or soft. 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:
configEpochvars are set to 0.
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.
Simple string reply:
OK if the command was successful. Otherwise an error is returned.
