## Install DRBD while installing HwameiStor

You can directly enable the DRBD component when installing HwameiStor.
For details, please refer to [Install HwameiStor with Operator](deploy-operator.md).

1. Go to __Container Management__ -> __Helm Charts__, and select __drbd-adapter__.

2. Click __drbd-adapter__, click __Install__ , and enter the configuration page.

    ![drbd02](https://docs.daocloud.io/daocloud-docs-images/docs/en/docs/storage/hwameistor/img/drbd02.png)

    - __Namespace__ : It is recommended to deploy in the same namespace as HwameiStor. The namespace created in this example is HwameiStor.
    - __Version__ : Select the latest version by default.
    - __Deletion failed__ : Turned off by default. When enabled, it will wait for the application to be installed by default, and will delete the installation in case of installation failure.
    - __Wait__ : Turned off by default. When enabled, it will wait for all resources associated with the application to be ready before marking the application as successfully installed.
    - __Detailed Logs__ : Turned off by default. Enable detailed output of installation process logs.

3. Click __OK__ to complete the creation.

## Install with Helm

Deploy the following `DaemonSet`. It will start a pod on each Kubernetes worker node to install the DRBD module and tools.

```bash
helm repo add drbd-adapter https://hwameistor.io/drbd-adapter/
helm repo update drbd-adapter
helm pull drbd-adapter/drbd-adapter --untar
helm install drbd-adapter ./drbd-adapter -n hwameistor --create-namespace
```

!!! tip

    Users in Chinese mainland can use the image repository `daocloud.io/daocloud` for acceleration:

    ```bash
    helm install drbd-adapter ./drbd-adapter \
        -n hwameistor --create-namespace \
        --set imagePullPolicy=Always \
        --set registry=daocloud.io/daocloud
    ```
