<p>I have deployed my running application in AKS. I want to add new disk (Harddisk of 30GB) but I don't know how to do it.</p>
<p>I want to attach 3 disks.</p>
<p>Here is details of AKS:</p>
<ul>
<li>Node size: <code>Standard_DS2_v2</code></li>
<li>Node pools: <code>1 node pool</code></li>
<li>Storage is:</li>
</ul>
<hr />
<pre><code>default (default)   kubernetes.io/azure-disk   Delete          WaitForFirstConsumer   true
</code></pre>
<p>Please, tell me how to add it.</p>

<p>Based on <a href="https://kubernetes.io/docs/concepts/storage/persistent-volumes/#:%7E:text=A%20PersistentVolume%20(PV)%20is%20a,node%20is%20a%20cluster%20resource.&amp;text=Pods%20can%20request%20specific%20levels%20of%20resources%20(CPU%20and%20Memory)." rel="nofollow noreferrer">Kubernetes documentation</a>:</p>
<blockquote>
<p>A <em>PersistentVolume</em> (PV) is a piece of storage in the cluster that has been provisioned by an administrator or dynamically provisioned using <a href="https://kubernetes.io/docs/concepts/storage/storage-classes/" rel="nofollow noreferrer">Storage Classes</a>.</p>
<p>It is a resource in the cluster just like a node is a cluster resource. PVs are volume plugins like Volumes, but have a lifecycle independent of any individual Pod that uses the PV.</p>

<p>In the <a href="https://learn.microsoft.com/en-us/azure/aks/concepts-storage#persistent-volumes" rel="nofollow noreferrer">Azure documentation</a> one can find clear guides how to:</p>
<ul>
<li><a href="https://learn.microsoft.com/en-us/azure/aks/azure-disk-volume" rel="nofollow noreferrer"><em>create a static volume using Azure Disks</em></a></li>
<li><a href="https://learn.microsoft.com/en-us/azure/aks/azure-files-volume" rel="nofollow noreferrer"><em>create a static volume using Azure Files</em></a></li>
<li><a href="https://learn.microsoft.com/en-us/azure/aks/azure-disks-dynamic-pv" rel="nofollow noreferrer"><em>create a dynamic volume using Azure Disks</em></a></li>
<li><a href="https://learn.microsoft.com/en-us/azure/aks/azure-files-dynamic-pv" rel="nofollow noreferrer"><em>create a dynamic volume using Azure Files</em></a></li>
</ul>
<p><strong>NOTE</strong>:
Before you begin you should have <a href="https://learn.microsoft.com/en-us/azure/aks/kubernetes-walkthrough" rel="nofollow noreferrer">existing AKS cluster</a> and Azure CLI version 2.0.59 or <a href="https://learn.microsoft.com/en-us/cli/azure/install-azure-cli" rel="nofollow noreferrer">later installed</a> and configured. To check your version run:</p>
<pre><code>az --version
</code></pre>
