# operator raft
This command groups subcommands for operators to manage the integrated Raft storage backend.
```text
Usage: vault operator raft <subcommand> [options] [args]
This command groups subcommands for operators interacting with the Vault
integrated Raft storage backend. Most users will not need to interact with these
commands. Here are a few examples of the Raft operator commands:
Subcommands:
join Joins a node to the Raft cluster
list-peers Returns the Raft peer set
remove-peer Removes a node from the Raft cluster
snapshot Restores and saves snapshots from the Raft cluster
```
## join
This command is used to join a new node as a peer to the Raft cluster. In order
to join, there must be at least one existing member of the cluster. If Shamir
seal is in use, then this API will request for the unseal keys to be supplied to
join the cluster.
```text
Usage: vault operator raft join [options] <leader-api-addr>
Join the current node as a peer to the Raft cluster by providing the address
of the Raft leader node.
$ vault operator raft join "http://127.0.0.2:8200"
```
### Parameters
The following flags are available for the `operator raft join` command.
- `-leader-ca-cert` `(string: "")` - CA cert to communicate with Raft leader.
- `-leader-client-cert` `(string: "")` - Client cert to to authenticate to Raft leader.
- `-leader-client-key` `(string: "")` - Client key to to authenticate to Raft leader.
- `-non-voter` `(bool: false) (enterprise)` - This flag is used to make the
server not participate in the Raft quorum, and have it only receive the data
replication stream. This can be used to add read scalability to a cluster in
cases where a high volume of reads to servers are needed. The default is false.
- `-retry` `(bool: false)` - Continuously retry joining the Raft cluster upon
failures. The default is false.
## list-peers
This command is used to list the full set of peers in the Raft cluster.
```text
Usage: vault operator raft list-peers
Provides the details of all the peers in the Raft cluster.
$ vault operator raft list-peers
```
### Example Output
```python
{
...
"data": {
"config": {
"index": 62,
"servers": [
{
"address": "127.0.0.2:8201",
"leader": true,
"node_id": "node1",
"protocol_version": "3",
"voter": true
},
{
"address": "127.0.0.4:8201",
"leader": false,
"node_id": "node3",
"protocol_version": "3",
"voter": true
}
]
}
}
}
```
## remove-peer
This command is used to remove a node from being a peer to the Raft cluster. In
certain cases where a peer may be left behind in the Raft configuration even
though the server is no longer present and known to the cluster, this command
can be used to remove the failed server so that it is no longer affects the Raft
quorum.
```text
Usage: vault operator raft remove-peer <server_id>
Removes a node from the Raft cluster.
$ vault operator raft remove-peer node1
```
## snapshot
This command groups subcommands for operators interacting with the snapshot
functionality of the integrated Raft storage backend. There are 2 subcommands
supported: `save` and `restore`.
```text
Usage: vault operator raft snapshot <subcommand> [options] [args]
This command groups subcommands for operators interacting with the snapshot
functionality of the integrated Raft storage backend.
Subcommands:
restore Installs the provided snapshot, returning the cluster to the state defined in it
save Saves a snapshot of the current state of the Raft cluster into a file
```
### snapshot save
Takes a snapshot of the Vault data. The snapshot can be used to restore Vault to
the point in time when a snapshot was taken.
```text
Usage: vault operator raft snapshot save <snapshot_file>
Saves a snapshot of the current state of the Raft cluster into a file.
$ vault operator raft snapshot save raft.snap
```
### snapshot restore
Restores a snapshot of Vault data taken with `vault operator raft snapshot save`.
```text
Usage: vault operator raft snapshot restore <snapshot_file>
Installs the provided snapshot, returning the cluster to the state defined in it.
$ vault operator raft snapshot restore raft.snap
```
