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.

@return

@simple-string-reply: `OK` or an error if the operation fails.
