A note about the word slave used in this man page and command name: Starting with Redis 5 this command: starting with Redis version 5, if not for backward compatibility, the Redis project no longer uses the word slave. Please use the new command CLUSTER REPLICAS. The command SLAVEOF will continue to work for backward compatibility.
The command provides a list of replica nodes replicating from the specified master node. The list is provided in the same format used by CLUSTER NODES (please refer to its documentation for the specification of the format).
The command will fail if the specified node is not known or if it is not a master according to the node table of the node receiving the command.
Note that if a replica is added, moved, or removed from a given master node, and we ask CLUSTER SLAVES to a node that has not yet received the configuration update, it may show stale information. However eventually (in a matter of seconds if there are no network partitions) all the nodes will agree about the set of nodes associated with a given master.
*返回值
The command returns data in the same format as CLUSTER NODES.
