## Introduction

If you want to reboot a bare metal server that is registered as a node in your cluster (which should already be set up per the [Hetzner account preparation](/docs/hetzner/apalla/getting-started/hetzner-account-preparation) guide), the easiest way is to reprovision it.

This can be done just by deleting the `Machine` object associated with the bare metal node.

However, in some cases it might be useful to reboot the machine in-place, such as when the local disk contains data which would require too much time to re-sync.

This guide will explain how you can do that.

## Step 1: Set the paused annotation

In the Autopilot cluster, set the paused annotation for the machine:

```shell
kubectl annotate machine your-cluster-md-abc-xyz-ijk cluster.x-k8s.io/paused=true
```

Double-check that you don't have a typo in the annotation. Otherwise, the node will get flagged as not functional and the machine will get reprovisioned.

## Step 2: Drain the node

In your workload cluster, drain the node:

```shell
kubectl drain bm-your-cluster-12345678 --ignore-daemonsets
```

And wait until all the pods are terminated. You can check with this command:

```shell
kubectl get pods --all-namespaces --field-selector spec.nodeName=bm-your-cluster-12345678
```

## Step 3: Reboot the server

Now, you can SSH into the server, and perform any needed maintenance tasks.

If you are unsure how to do that, refer to the [How to SSH into nodes](/docs/hetzner/apalla/how-to-guides/server-management/sshing-into-nodes) guide.

For rebooting it, type this in the server shell:

```shell
reboot
```

## Step 4: Add the node back

First, uncordon the node in your workload cluster:

```shell
kubectl uncordon bm-your-cluster-12345678
```

And, in the Autopilot cluster, remove the pause annotation:

```shell
kubectl annotate machine your-cluster-md-abc-xyz-ijk cluster.x-k8s.io/paused-
```

Now the node is a functional member of the cluster again.
