CLUSTER SAVECONFIG writes the node’s view of the cluster (nodes, slots, epochs) to its cluster configuration file, cluster-config-file (nodes.conf by default), before it replies. The node already saves the file whenever its configuration changes; use this command to make sure, for example before a backup, or to check that the file can be written.

Return value

Section titled “Return value”

Simple string OK in RESP2 and RESP3, or one of these errors:

Case Error
The file could not be written ERR error saving the cluster node config: <reason>
Cluster mode is off ERR This instance has cluster support disabled

Examples

Section titled “Examples”
