<p>I have a kubernetes cluster on the eks of aws. I use aws-ebs as the Provisioner of StorageClass, and the ReclaimPolicy is set to Retain. I install the application with helm. When I delete the application, the pvc is deleted, but the pv still exists. The status is Released. I can see that the aws-ebs volume is still in the aws console. Now I want to create a new application and still use the original data. I think there are two ways to do it</p>
<ol>
<li>Manually create a pvc to bind this pv to make pv work again, but the StorageClass cannot be used</li>
<li>Re-create a new PV to bind aws-ebs and then create a new PVC through this PV, it seems that StorageClass cannot be used</li>
</ol>
<p>But I don’t know how to change it, can I ask for help?   thanks in advance</p>

<p>The <a href="https://kubernetes.io/docs/concepts/storage/persistent-volumes/#retain" rel="nofollow noreferrer">ReclaimPolicy: Retain</a> means that:</p>
<blockquote>
<p>The <code>Retain</code> reclaim policy allows for manual reclamation of the
resource. When the PersistentVolumeClaim is deleted, the
PersistentVolume still exists and the volume is considered &quot;released&quot;.
But it is not yet available for another claim because the previous
claimant's data remains on the volume. An administrator can manually
reclaim the volume with the following steps.</p>
<ol>
<li><p>Delete the PersistentVolume. The associated storage asset in external infrastructure (such as an AWS EBS, GCE PD, Azure Disk, or
Cinder volume) still exists after the PV is deleted.</p>
</li>
<li><p>Manually clean up the data on the associated storage asset accordingly.</p>
</li>
<li><p>Manually delete the associated storage asset, or if you want to reuse the same storage asset, create a new PersistentVolume with the
storage asset definition.</p>
</li>
</ol>
