title: Why am I getting "Structure needs cleaning" message on Ceph with Kubernetes?
body: <p>Sorry to ask this, I am relatively new in Kubernetes and Ceph, only have a little idea about this.</p>
  
  <p>I have setup Kubernetes and Ceph using this tutorial(<a href="http://tutorial.kubernetes.noverit.com/content/ceph.html" rel="nofollow noreferrer">http://tutorial.kubernetes.noverit.com/content/ceph.html</a>)</p>
  
  <p>I had set up my cluster like this:</p>
  
  <p>1 Kube-Master and 2 worker Nodes(this acts ceph monitor with 2 OSD in each)<br>
  The ceph-deploy I used to setup ceph cluster is in the Kube-master.</p>
  
  <p>Everything is working fine, I installed my sample web application(deployment)  with 5 replicas, which will create a file when the rest API is hit. The file is getting copied to every node.</p>
  
  <p>But after 10 min, I created one more file using the API, but when I try to list(ls -l) I am getting the following error:</p>
  
  <p>For node1:</p>
  
  <pre><code>ls: cannot access 'previousFile.txt': Structure needs cleaning
  previousFile.txt  newFile.txt
  </code></pre>
  
  <p>For node2:</p>
  
  <pre><code>previousFile.txt  
  </code></pre>
  
  <p>For node2 the new file is not created </p>
  
  <p>What might be the issue? I have tried many times still same error pop up. </p>
  
  <p>Any help appreciated.</p>
