# `/sys/storage/raft/autopilot`
The `/sys/storage/raft/autopilot` endpoints are used to manage raft clusters using autopilot
with Vault's [Integrated Storage backend](/docs/internals/integrated-storage).
Refer to the [Integrated Storage Autopilot](https://learn.hashicorp.com/tutorials/vault/raft-autopilot?in=vault/raft) tutorial to learn how to manage raft clusters using autopilot.
## Get Cluster State
This endpoint is used to retrieve the raft cluster state. See the [docs page](/docs/commands/operator/raft#autopilot-state) for a description of the output.
| Method | Path |
| :----- | :---------------------------------- |
| `GET` | `/sys/storage/raft/autopilot/state` |
### Sample Request
```shell-session
$ curl \
--header "X-Vault-Token: ..." \
http://127.0.0.1:8200/v1/sys/storage/raft/autopilot/state
```
### Sample Response
```json

}
},
"leader": "raft1",
"voters": ["raft1", "raft2", "raft3"],
"non_voters": null
}
```
### Enterprise Only
Vault Enterprise will include additional output in its API response to indicate the current state of redundancy zones,
automated upgrade progress (if any), and optimistic failure tolerance.
#### Sample Response (Enterprise)
```json
{
"failure_tolerance": 0,
"healthy": true,
"leader": "vault_1",
"optimistic_failure_tolerance": 3,
"redundancy_zones": {
"a": {
"servers": [
"vault_1",
"vault_2",
"vault_5"
],
"voters": [
"vault_1"
],
"failure_tolerance": 2
},
"b": {
"servers": [
"vault_3",
"vault_4"
],
"voters": [
"vault_3"
],
"failure_tolerance": 1
}
},
"upgrade_info": {
"other_version_non_voters": [

"vault_4"
],
"other_version_voters": [

]
},

"target_version_non_voters": [
"vault_5"
]
},
"voters": [
"vault_1",
"vault_3"
]
}
```
## 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
```shell-session
$ curl \
--header "X-Vault-Token: ..." \
http://127.0.0.1:8200/v1/sys/storage/raft/autopilot/configuration
```
### Sample Response
```json
{
"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",
"disable_upgrade_migration": true
}
```
Note that in the above sample response, `disable_upgrade_migration` is an Enterprise-only field.
## 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 `true`.
- `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.
- `disable_upgrade_migration` `(bool: false)` - Disables automatically upgrading Vault using
autopilot. (Enterprise-only)
### Sample Request
```shell-session
$ curl \
--header "X-Vault-Token: ..." \
--request POST \
--data @payload.json \
http://127.0.0.1:8200/v1/sys/storage/raft/autopilot/configuration
```
### Sample Payload
```json
{
"cleanup_dead_servers": true,
"last_contact_threshold": "10s",
"dead_server_last_contact_threshold": "24h",
"max_trailing_logs": "1000",
"min_quorum": "3",
"server_stabilization_time": "10s",
"disable_upgrade_migration": true
}
```
Note that in the above sample payload, `disable_upgrade_migration` is an Enterprise-only field.
