title: can't upload a big file to persistent volume
body: <p>I created a persistent volume, claim (10Gi) and mounted on a pod. Below are the YAML file.
  <a href="https://i.stack.imgur.com/fDMci.png" rel="nofollow noreferrer">YAML file</a></p>
  
  <p>My intention is to upload a big file to persistent volume by</p>
  
  <pre><code>kuberctl cp [local file path] namespace/pod_name:/mount_path
  </code></pre>
  
  <p>I expected the mount path should be of 10Gi (as of PV). Instead it's 4KB. hence I can not upload a big file. </p>
  
  <p>Below is the error when I try to upload a big file:</p>
  
  <pre><code>tar: file_name: Wrote only 2560 of 10240 bytes
  tar: Exiting with failure status due to previous errors
  command terminated with exit code 2
  </code></pre>
  
  <p>Which is I guess because directories doesn't have space. Any idea on what I'm doing wrong? any help would be appreciated.</p>
