Until you keep pvc your pv will be in Bound state. So you can just go and delete unused pvc with:

If you'd like to remove all the Unbound PVs and PVCs, you can do this:

First delete the PVCs:

<pre><code>$ kubectl -n &lt;namespace&gt; get pvc | tail -n +2 | grep -v Bound | \
 awk '{print $1}' | xargs -I{} kubectl -n namespace delete pvc {}
</code></pre>

Then just delete the PVs:

<pre><code>$ kubectl -n &lt;namespace&gt; get pv | tail -n +2 | grep -v Bound | \
 awk '{print $1}' | xargs -I{} kubectl -n namespace delete pv {}
</code></pre>

blocks|key|1576183|text|是的，首先你需要删除未使用的PVC。使用kubectl+get+pvc+--all-namespaces，您可以在所有名称空间中列出所有名称空间中的所有名称空间以及相应的PV。为了删除未使用的PV，您需要更改它的ReclaimPolicy，因为如果它被设置为保留，则不会删除PV，而是会挂起“释放”状态。因此，要做到这一点，您需要修补PV+(由于某些原因，无法用kubectl+edit手动编辑它)：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1576184|kubectl+patch+pv+<your-pv-name>+-p+'{"spec":{"persistentVolumeReclaimPolicy":"Delete"}}'|code-block|syntax|javascript|1576185|entityMap^0|K|W|51|C|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|L|$]]

Yeah, first you need to delete unused PVC. 
With <code>kubectl get pvc --all-namespaces</code> you can list all of them in all namespaces along with the corresponding PVs.
In order to delete unused PVs you need to change its ReclaimPolicy because if it's set to Retain the PVs won't be deleted but will hang in "Released" status. So in order to do that you need to patch PV (it's not possible to edit it manually with <code>kubectl edit</code> for some reason):

<pre><code>kubectl patch pv &lt;your-pv-name&gt; -p '{"spec":{"persistentVolumeReclaimPolicy":"Delete"}}'
</code></pre>

Looking through the current answers it looks like most of these don't directly answer the question (I could be mistaken). A PVC that is <code>Bound</code> is not the same as <code>Mounted</code>. The current answers should suffice to clean up <code>Unbound</code> PVC's, but finding and cleaning up all <code>Unmounted</code> PVC's seems unanswered.

Unfortunately it looks like the <code>-o=go-template=...</code> doesn't have a variable for <code>Mounted By:</code> as shown in <code>kubectl describe pvc</code>.

Here's what I've come up with after some hacking around:

To list all PVC's in a cluster (mounted and not mounted) you can do this: <code>kubectl describe -A pvc | grep -E "^Name:.*$|^Namespace:.*$|^Mounted By:.*$"</code>

The <code>-A</code> will return every PVC in the cluster in every namespace. We then filter down to show just the <code>Name</code>, <code>Namespace</code> and <code>Mounted By</code> fields.

The best I could come up with to then get the names and namespaces of all unmounted PVC's is this:

<pre><code>kubectl describe -A pvc | grep -E "^Name:.*$|^Namespace:.*$|^Mounted By:.*$" | grep -B 2 "&lt;none&gt;" | grep -E "^Name:.*$|^Namespace:.*$"
</code></pre>

To actually delete the PVC's is somewhat difficult because we need to know the name of the PVC as well as it's namespace. We use cut, paste and xargs to do this:

<pre><code>kubectl describe -A pvc | grep -E "^Name:.*$|^Namespace:.*$|^Mounted By:.*$" | grep -B 2 "&lt;none&gt;" | grep -E "^Name:.*$|^Namespace:.*$" | cut -f2 -d: | paste -d " " - - | xargs -n2 bash -c 'kubectl -n ${1} delete pvc ${0}'
</code></pre>

<ul>
<li><code>cut</code> removes <code>Name:</code> and <code>Namespace:</code> since they just get in the way</li>
<li><code>paste</code> puts the <code>Name</code> of the PVC and it's <code>Namespace</code> on the same line</li>
<li><code>xargs -n bash</code> makes it so the PVC name is <code>${0}</code> and the namespace is <code>${1}</code>.</li>
</ul>

I admit that I have a feeling that this isn't the best way to do this but it was the only obvious way I could come up with (on the CLI) to do this.

After running this your volumes will go from <code>Bound</code> to <code>Unbound</code> and the other answers in this thread have good ideas on how to clean those up.

Also, keep in mind that some of the volume controllers don't actually delete your data when the volumes are deleted in Kubernetes. You might still need to clean that up in whichever system you are using.

For example, in the NFS controller the data gets renamed with an <code>archived-</code> prefix and on the NFS side you can run <code>rm -rf /persistentvolumes/archived-*</code>. For AWS EBS you might still need to delete the EBS volumes if they are detached from any instance.

I hope this helps!

All previous answsers are valid and interesting. Here is another simple way to delete persistent volumes.

You should first delete your associated persistentvolumeclaim but in some cases the persistentvolumes could not be deleted automaticaly. (Ex : a "Retain" reclaim policy).

Here is a safe syntax for persistentvolumes deletion with Released satus (unused and unmounted).

<pre><code>kubectl get --no-headers persistentvolumes|awk '$5=="Released" { print $1 }'|xargs echo "kubectl delete persistentvolumes"
</code></pre>

We don't want to delete PV and PVC as pods reuse them most of the times.
However, in the long term, we end up with many PVs' and PVCs' that are not used.

How to delete only unmounted PVCs and PVs?
