<p>So I am running a k3s cluster on 3 RHEL 8 Servers and I want to uninstall Longhorn from the cluster using <code>helm uninstall longhorn -n longhorn-system</code></p>
<p>Now all Longhorn pods, pvcs, etc. got deleted but one volume remained that is stuck in state deleting!
Here some additional infos about the volume:</p>
<pre><code>Name:         pvc-f1df1bf8-96f4-4b28-a14d-2b20809610df

<p>I tried to remove the finalizers but that didn't help for me. Does anyone have an idea why that volume can't be uninstalled?</p>

<p>If you deleted the PVC and also used the command for the finalizers it means some resources associated with this PV are still running. Maybe in a different namespace.
First, run this command again to make sure the finalizers are applied correctly.</p>
<pre><code>kubectl patch pv &lt;pv_name&gt; -p '{&quot;metadata&quot;:{&quot;finalizers&quot;:null}}'

                          and then 

kubectl delete pv &lt;pv_name&gt; --grace-period=0 --force 
</code></pre>
<p>If still PV not deleted then check the resources with this command.</p>
<pre><code>PVC_NAME=&quot;&lt;pvc-name&gt;&quot;; kubectl get pods,deployments,statefulsets,daemonsets,replicasets,jobs,cronjobs --all-namespaces -o json | jq --arg PVC &quot;$PVC_NAME&quot; '.items[] | select(.spec.template.spec.volumes[]?.persistentVolumeClaim.claimName == $PVC) | .metadata.namespace + &quot;/&quot; + .metadata.name + &quot; (&quot; + .kind + &quot;)&quot;'
</code></pre>
<p>This will return the info where this PV is being used and then delete those resources manually. Once you delete those resources PV will be deleted. I hope this helps.</p>
