Enable DR primary replication

This endpoint enables DR replication in primary mode. This is used when DR replication is currently disabled on the cluster (if the cluster is already a secondary, it must be promoted).

Parameters

• primary_cluster_addr (string: "") – Specifies the cluster address that the primary gives to secondary nodes. Useful if the primary's cluster address is not directly accessible and must be accessed via an alternate path/address, such as through a TCP-based load balancer.

Sample payload

{}

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/primary/enable

Demote DR primary

This endpoint demotes a DR primary cluster to a secondary. This DR secondary cluster will not attempt to connect to a primary (see the update-primary call), but will maintain knowledge of its cluster ID and can be reconnected to the same DR replication set without wiping local storage.

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    http://127.0.0.1:8200/v1/sys/replication/dr/primary/demote

Disable DR primary

This endpoint disables DR replication entirely on the cluster. Any secondaries will no longer be able to connect. Caution: re-enabling this node as a primary or secondary will change its cluster ID; in the secondary case this means a wipe of the underlying storage when connected to a primary, and in the primary case, secondaries connecting back to the cluster (even if they have connected before) will require a wipe of the underlying storage.

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    http://127.0.0.1:8200/v1/sys/replication/dr/primary/disable

Generate DR secondary token

This endpoint generates a DR secondary activation token for the cluster with the given opaque identifier, which must be unique. This identifier can later be used to revoke a DR secondary's access.

This endpoint requires 'sudo' capability.

Parameters

• id (string: <required>) – Specifies an opaque identifier, e.g. 'us-east'

• ttl (string: "30m") – Specifies the TTL for the secondary activation token.

• secondary_public_key (string: "") – Specifies the secondary's generated public key, if using encryption rather than response wrapping to protect the secondary credentials. (Vault 1.3+). Use this to avoid making an API call to the primary during secondary activation.

Sample payload

{
  "id": "us-east-1"
}

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/primary/secondary-token

Sample response

{
  "request_id": "",
  "lease_id": "",
  "lease_duration": 0,
  "renewable": false,
  "data": null,
  "warnings": null,
  "wrap_info": {

    "creation_time": "2016-09-28T14:41:00.56961496-04:00",
    "wrapped_accessor": ""
  }
}

Revoke DR secondary token

This endpoint revokes a DR secondary's ability to connect to the DR primary cluster; the DR secondary will immediately be disconnected and will not be allowed to connect again unless given a new activation token. This command can be run from any node on the DR primary cluster.

Parameters

• id (string: <required>) – Specifies an opaque identifier, e.g. 'us-east'

Sample payload

{
  "id": "us-east"
}

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/primary/revoke-secondary

Generate DR secondary public key

This endpoint allows generating a public key that is used to encrypt the returned credential information (instead of using a response wrapped token). This avoids needing to make an API call to the primary during activation.

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/generate-public-key

Enable DR secondary

This endpoint enables replication on a DR secondary using a DR secondary activation token.

Parameters

• token (string: <required>) – Specifies the secondary activation token fetched from the primary.

• primary_api_addr (string: "") – Set this to the API address (normal Vault address) to override the value embedded in the token. This can be useful if the primary's redirect address is not accessible directly from this cluster (e.g. through a load balancer).

• ca_file (string: "") – Specifies the path to a CA root file (PEM format) that the secondary can use when unwrapping the token from the primary. If this and ca_path are not given, defaults to system CA roots.

• ca_path (string: "") – Specifies the path to a CA root directory containing PEM-format files that the secondary can use when unwrapping the token from the primary. If this and ca_file are not given, defaults to system CA roots.

Sample payload

{
  "token": "..."
}

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/enable

Promote DR secondary

This endpoint promotes the DR secondary cluster to DR primary. For data safety and security reasons, new secondary tokens will need to be issued to other secondaries, and there should never be more than one primary at a time.

If the DR secondary's primary cluster is also in a performance replication set, the DR secondary will be promoted into that replication set. Care should be taken when promoting to ensure multiple performance primary clusters are not active at the same time.

If the DR secondary's primary cluster is a performance secondary, the promoted cluster will attempt to connect to the performance primary cluster using the same secondary token.

This endpoint requires a DR Operation Token to be provided as means of authorization. See the DR Operation Token API docs for more information.

Parameters

• dr_operation_token (string: <required>) - DR operation token used to authorize this request.
• primary_cluster_addr (string: "") – Specifies the cluster address that the primary gives to secondary nodes. Useful if the primary's cluster address is not directly accessible and must be accessed via an alternate path/address (e.g. through a load balancer).
• force (bool: false) - If true the cluster will be promoted even if it fails certain safety checks. Caution: Forcing promotion could result in data loss if data isn't fully replicated.

Sample payload

{
  "dr_operation_token": "ijH8tphEHaBtgx+IvPfxDsSi2LV4j9k+Lad6eqT5cJw="
}

Disable DR secondary

This endpoint disables DR replication entirely on the cluster. The cluster will no longer be able to connect to the DR primary.

This endpoint requires a DR Operation Token to be provided as means of authorization. See the DR Operation Token API docs for more information.

Sample payload

{
  "dr_operation_token": "..."
}

Sample request

$ curl \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/disable

Update DR secondary's primary

The update endpoint changes the primary cluster assigned to a DR secondary cluster. Changing the primary cluster assignment does not wipe data in the secondary cluster.

This endpoint requires a DR Operation Token to be provided as means of authorization. See the DR Operation Token API docs for more information.

There are two ways to update the primary assignment:

1. Use a secondary activation token with the token parameter. An activation token is required after a DR failover when updating a newly demoted DR secondary cluster.

2. Use primary cluster addresses with the update_primary_addrs parameter. During the update, cluster addresses are pinged one at a time via gRPC. The first cluster to respond successfully is assigned as the new primary address. Updating with cluster addresses is not allowed after a DR failover when updating a newly demoted DR secondary cluster.

The two update methods are mutually exclusive. You may use one or the other, but not both. A good rule of thumb is to use token on DR secondary clusters and update_primary_addrs on performance secondary clusters.

Parameters

• dr_operation_token (string: <required>) - DR operation token used to authorize this request.

• token (string: <required>) – Specifies the secondary activation token fetched from the primary. If you set this to a blank string, the cluster will stay a secondary but clear its knowledge of any past primary (and thus not attempt to connect to the previous primary). This can be useful if the primary is down to stop the secondary from trying to reconnect to it.

• primary_api_addr (string: ) – Specifies the API address (normal Vault address) to override the value embedded in the token. This can be useful if the primary's redirect address is not accessible directly from this cluster.

• ca_file (string: "") – Specifies the path to a CA root file (PEM format) that the secondary can use when unwrapping the token from the primary. If this and ca_path are not given, defaults to system CA roots.

• ca_path string: () – Specifies the path to a CA root directory containing PEM-format files that the secondary can use when unwrapping the token from the primary. If this and ca_file are not given, defaults to system CA roots.

• update_primary_addrs array: [] – List of cluster addresses for potential primary clusters. These addresses will be pinged in sequence, and if any of them respond successfully, these will be recorded as the new primary addresses. This is a lighter weight version of specifying a token and should result in less disruption of replication.

Generate disaster recovery operation token

The /sys/replication/dr/secondary/generate-operation-token endpoint is used to create a new Disaster Recovery operation token for a DR secondary. These tokens are used to authorize certain DR Operations. They should be treated like traditional root tokens by being generated when needed and deleted soon after.

Read generation progress

This endpoint reads the configuration and process of the current generation attempt.

Sample request

$ curl \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/generate-operation-token/attempt

Sample response

{
  "started": true,
  "nonce": "2dbd10f1-8528-6246-09e7-82b25b8aba63",
  "progress": 1,
  "required": 3,
  "encoded_token": "",
  "pgp_fingerprint": "",
  "complete": false
}

If a generation is started, progress is how many unseal keys have been provided for this generation attempt, where required must be reached to complete. The nonce for the current attempt and whether the attempt is complete is also displayed. If a PGP key is being used to encrypt the final token, its fingerprint will be returned. Note that if an OTP is being used to encode the final token, it will never be returned.

Start token generation

This endpoint initializes a new generation attempt. Only a single generation attempt can take place at a time.

Parameters

• pgp_key (string: <optional>) – Specifies a base64-encoded PGP public key. The raw bytes of the token will be encrypted with this value before being returned to the final unseal key provider.

Sample request

$ curl \
    --request POST \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/generate-operation-token/attempt

Sample response

{
  "started": true,
  "nonce": "2dbd10f1-8528-6246-09e7-82b25b8aba63",
  "progress": 1,
  "required": 3,
  "encoded_token": "",
  "otp": "2vPFYG8gUSW9npwzyvxXMug0",
  "otp_length": 24,
  "complete": false
}

Cancel generation

This endpoint cancels any in-progress generation attempt. This clears any progress made. This must be called to change the OTP or PGP key being used.

Sample request

$ curl \
    --request DELETE \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/generate-operation-token/attempt

Provide key share to generate token

This endpoint is used to enter a single root key share to progress the generation attempt. If the threshold number of root key shares is reached, Vault will complete the generation and issue the new token. Otherwise, this API must be called multiple times until that threshold is met. The attempt nonce must be provided with each call.

Parameters

• key (string: <required>) – Specifies a single root key share.

• nonce (string: <required>) – Specifies the nonce of the attempt.

Sample payload

{
  "key": "acbd1234",
  "nonce": "ad235"
}

Sample request

$ curl \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/generate-operation-token/update

Sample response

This returns a JSON-encoded object indicating the attempt nonce, and completion status, and the encoded token, if the attempt is complete.

{
  "started": true,
  "nonce": "2dbd10f1-8528-6246-09e7-82b25b8aba63",
  "progress": 3,
  "required": 3,
  "pgp_fingerprint": "",
  "complete": true,
  "encoded_token": "FPzkNBvwNDeFh4SmGA8c+w=="
}

Delete DR operation token

This endpoint revokes the DR Operation Token. This token does not have a TTL and therefore should be deleted when it is no longer needed.

Parameters

• dr_operation_token (string: <required>) - DR operation token used to authorize this request.

Sample payload

{
  "dr_operation_token": "..."
}

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/operation-token/delete

Reindex Replication

This endpoint reindexes the local data storage. This can cause a very long delay depending on the number and size of objects in the data store.

This endpoint requires a disaster recovery operation token.

Parameters

• diff (bool: false) – Enables a slower re-indexing which will perform a key level check to diagnose issues. Defaults false.

• force (bool: false) – Forces a complete re-indexing which only scans data available in the storage. Defaults false.

• skip_flush (bool: false) – Skips the tree flushing stage of the reindex process. This setting can be used to reduce the amount of time the tree is locked during a reindex process. If this node is killed before the full tree has been asynchronously flushed the reindex may not have applied fully and a new reindex may need to be done. Defaults false.

• dr_operation_token (string: <required>) - DR operation token used to authorize this request.

Sample Payload

{
  "dr_operation_token": "..."
}

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/reindex

Sample Response

{
  "warnings": ["..."]
}

/sys/replication/dr/secondary/merkle-check

The Merkle check endpoint prints information about the corruption status of the Merkle tree on a DR secondary cluster. Check merkle tree corruption for more details.

Requests to /sys/replication/dr/secondary/merkle-check must provide a DR Operation Token as authorization. See the DR Operation Token API docs for more information.

Parameters

• dr_operation_token (string: <required>) - DR operation token used to authorize the request.

Sample request

$ curl \
    http://127.0.0.1:8200/v1/sys/replication/dr/secondary/merkle-check

Sample response

The response provides information about the health of the Merkle composite tree. It indicates whether the root of the tree is corrupted and also identifies any corruption in the roots of its subtrees, including replicated and local subtrees. In the event of corruption within a page or subpage of the tree, it includes the page number along with a list of corrupted subpage numbers. The status details indicate the extent of corruption within the Merkle tree.
