title: Two questions about the "No space left on device" error of my vagrant vm
body: <p>I git cloned a project which uses Vagrant. I used to have everything working with Vagrant, I mean I run <code>vagrant up</code> &amp; <code>vagrant ssh</code>, then start my web application project.</p>
  
  <p>Today, I ssh to my vagrant virtual box by <code>vagrant ssh</code>. Then under the virtual box, I import my database by:</p>
  
  <pre><code>$ mysql -u root -p mydb &lt; /vagrant/db.sql
  </code></pre>
  
  <p>After a while, I restarted my MacBook, then I bring up vagrant VM by command <code>vagrant up</code> under project folder. I start getting following error:</p>
  
  <pre><code>/opt/vagrant/embedded/gems/gems/net-scp-1.2.1/lib/net/scp.rb:398:in `await_response_state': scp: /tmp/vagrant-network-entry: No space left on device (RuntimeError)
  </code></pre>
  
  <p><strong>My first question:</strong>
  Is it because I import database to it so the space is running out?  </p>
  
  <p>(I know by googling, there are answers on how to increase space on Vagrant vm, but that's not I want)</p>
  
  <p><strong>My second question:</strong>
  How can I revert back to the state when I haven't imported the database? Imaging now I am not able to bring up (neither can SSH to)the Vagrant vm due to the above error.</p>
