Maintenance mode
|
|
================
|
|
|
|
In this mode, the node is not reachable from the outside, i.e.
|
|
|
|
* it refuses all incoming RPC connections,
|
|
* it does not join the cluster, thus
|
|
|
|
* all operations that need synchronizing with other nodes are disabled (e.g. schema changes),
|
|
* all cluster-wide operations are disabled for this node (e.g. repair),
|
|
* other nodes see this node as dead,
|
|
* cannot read or write data from/to other nodes,
|
|
* it does not open Alternator transport ports and the TCP CQL port.
|
|
|
|
The only way to make CQL queries is to use :doc:`the maintenance socket </operating-scylla/admin-tools/maintenance-socket/>`. The node serves only local data.
|
|
|
|
To start the node in maintenance mode, use the `--maintenance-mode true` flag or set `maintenance_mode: true` in the configuration file.
|
|
|
|
REST API works as usual, but some routes are disabled:
|
|
|
|
* authorization_cache
|
|
* failure_detector
|
|
* hinted_hand_off_manager
