Forces a node to save the cluster configuration to disk.
CLUSTER
SAVECONFIG
Forces a node to save the nodes.conf
configuration on
disk. Before to return the command calls fsync(2)
in order
to make sure the configuration is flushed on the computer disk.
This command is mainly used in the event a nodes.conf
node state file gets lost / deleted for some reason, and we want to
generate it again from scratch. It can also be useful in case of mundane
alterations of a node cluster configuration via the CLUSTER
command in order to ensure the new configuration is persisted on disk,
however all the commands should normally be able to auto schedule to
persist the configuration on disk when it is important to do so for the
correctness of the system in the event of a restart.
Simple string
reply: OK
if the command was successful. Otherwise an
error is returned.
