Get Cluster State

This endpoint is used to retrieve the raft cluster state. See the docs page for a description of the output.

Method	Path
`GET`	`/sys/storage/raft/autopilot/state`

Sample Request

$ curl \    --header "X-Vault-Token: ..." \    http://127.0.0.1:8200/v1/sys/storage/raft/autopilot/state

Sample Response

Get Configuration

This endpoint is used to get the configuration of the autopilot subsystem of integrated storage.

Method	Path
`GET`	`/sys/storage/raft/autopilot/configuration`

Sample Request

$ curl \    --header "X-Vault-Token: ..." \    http://127.0.0.1:8200/v1/sys/storage/raft/autopilot/configuration

Sample Response

{  "cleanup_dead_servers": false,  "dead_server_last_contact_threshold": "24h0m0s",  "last_contact_threshold": "10s",  "max_trailing_logs": 1000,  "min_quorum": 0,  "server_stabilization_time": "10s"}

Set Configuration

This endpoint is used to modify the configuration of the autopilot subsystem of integrated storage.

Method	Path
`POST`	`/sys/storage/raft/autopilot/configuration`

Parameters

cleanup_dead_servers (bool: false) - Controls whether to remove dead servers from the Raft peer list periodically or when a new server joins. This requires that min-quorum is also set.
last_contact_threshold (string: "10s") - Limit on the amount of time a server can go without leader contact before being considered unhealthy.
dead_server_last_contact_threshold (string: "24h") - Limit on the amount of time a server can go without leader contact before being considered failed. This takes effect only when cleanup_dead_servers is set.
max_trailing_logs (int: 1000) - Amount of entries in the Raft Log that a server can be behind before being considered unhealthy.
min_quorum (int: 3) - Minimum number of servers allowed in a cluster before autopilot can prune dead servers. This should at least be 3. Applicable only for voting nodes.
server_stabilization_time (string: "10s") - Minimum amount of time a server must be in a stable, healthy state before it can be added to the cluster.
