# Stopping and restarting a OpenSearch cluster

If necessary, you can stop and restart your OpenSearch cluster. When stopped, a cluster retains all its data. The data will be available again as soon as you restart the cluster.


You are not charged for the time when your cluster is stopped; however, you still pay for the storage size based on the [pricing policy](../pricing.md).

{% note alert %}

If a cluster uses local SSD storage (`local-ssd`), its computing resources are not released when it's stopped. This means that you are charged in full even for a stopped cluster.

## Stopping a cluster {#stop}

{% list tabs group=instructions %}

- Management console {#console}

    1. In the [management console](https://console.yandex.cloud), navigate to the folder page.
    1. Navigate to **Managed Service for OpenSearch**.
    1. Find the cluster in the list, click ![options](../../_assets/console-icons/ellipsis.svg), and select **Stop**.
    1. In the dialog box that opens, confirm that you want to stop the cluster and click **Stop**.

- REST API {#api}

    1. [Get an IAM token for API authentication](../api-ref/authentication.md) and put it into an environment variable:

        ```bash
        export IAM_TOKEN="<IAM_token>"
        ```

    1. Call the [Cluster.Stop](../api-ref/Cluster/stop.md) method, e.g., via the following [cURL](https://curl.se/) request:

        ```bash
        curl \
            --request GET \
            --header "Authorization: Bearer $IAM_TOKEN" \
            --url 'https://mdb.api.cloud.yandex.net/managed-opensearch/v1/clusters/<cluster_ID>:stop'
        ```

        You can get the cluster ID with the [list of clusters in the folder](cluster-list.md#list-clusters).

    1. Check the [server response](../api-ref/Cluster/stop.md#yandex.cloud.operation.Operation) to make sure your request was successful.

- gRPC API {#grpc-api}

    1. [Get an IAM token for API authentication](../api-ref/authentication.md) and put it into an environment variable:

        ```bash
        export IAM_TOKEN="<IAM_token>"
        ```

    1. Clone the [cloudapi](https://github.com/yandex-cloud/cloudapi) repository:
       
       ```bash
       cd ~/ && git clone --depth=1 https://github.com/yandex-cloud/cloudapi
       ```
       
       Below, we assume that the repository contents reside in the `~/cloudapi/` directory.
    1. Call the [ClusterService.Stop](../api-ref/grpc/Cluster/stop.md) method, e.g., via the following [gRPCurl](https://github.com/fullstorydev/grpcurl) request:

        ```bash
        grpcurl \
            -format json \
            -import-path ~/cloudapi/ \
            -import-path ~/cloudapi/third_party/googleapis/ \
            -proto ~/cloudapi/yandex/cloud/mdb/opensearch/v1/cluster_service.proto \
            -rpc-header "Authorization: Bearer $IAM_TOKEN" \
            -d '{
                  "cluster_id": "<cluster_ID>"
                }' \
            mdb.api.cloud.yandex.net:443 \
            yandex.cloud.mdb.opensearch.v1.ClusterService.Stop
        ```

        You can get the cluster ID with the [list of clusters in the folder](cluster-list.md#list-clusters).

    1. View the [server response](../api-ref/grpc/Cluster/stop.md#yandex.cloud.operation.Operation) to make sure your request was successful.

## Starting a cluster {#start}

You can restart **Stopped** clusters.
