<p>I restarted the Prometheus pod and now the Prometheus pod is crashlooping. Found this error in the logs:</p>
<pre><code>level=error ts=2021-06-09T09:27:29.066Z caller=main.go:758 err=&quot;opening storage failed: block dir: \&quot;/prometheus/01F6J0P4KBBWVJD2M8B1PE7C5E\&quot;: open /prometheus/01F6J0P4KBBWVJD2M8B1PE7C5E/meta.json: no such file or directory&quot;
</code></pre>
<p>Noticed that the <code>01F6J0P4KBBWVJD2M8B1PE7C5E</code> folder only has the chunks folder in it.</p>
<p>Any idea why this occurs and is there a way to fix this?</p>

<p>So you have already found correct github related issues and asked there also.</p>
<ul>
<li><p><a href="https://github.com/prometheus/prometheus/issues/7090" rel="noreferrer">Still seeing &quot;opening storage failed: block dir&quot; on more recent version of prometheus #7090</a></p>
</li>
<li><p><a href="https://github.com/prometheus/prometheus/issues/4058" rel="noreferrer">does not start up after corrupted meta.json file</a></p>
</li>
</ul>
<p>And seems currently the only way to fix the problem is to delete <code>01F6J0P4KBBWVJD2M8B1PE7C5E</code> folder that contains empty <code>meta.json</code> either nothing (<a href="https://github.com/prometheus/prometheus/issues/4058#issuecomment-426290403" rel="noreferrer">link</a>)</p>
