<p>I see the below error messages in the minishift logs. The rootDiskErr and rootInodeErr error is from fsHandler.go. Is this error related to filedescriptor limits or this error indicates other issues. Could anyone explain about this error.</p>

<p>my minishift vm fs limit,</p>

<pre><code>[docker@minishift ~]$ sysctl fs.file-nr
fs.file-nr = 2592   0   299016
</code></pre>

<p><code>No such file or directory</code>  happens when a container has not started or has already removed. Its <strong>harmless</strong> error </p>
