title: “Error response from daemon: Cannot start container … no such file or directory” on Oracle Linux running hello-world
body: <p>TLDR: I am trying to run the hello-world container on a Oracle Linux and I am getting an error message: Error response from daemon: Cannot start container 724ed94d9249b636d6820fb8c2e4ba64232f426812e5b03545762 532751f434e: [8] System error: mkdir /var/lib/docker/devicemapper/mnt/724ed94d9249b636d6820fb8c2e4ba6423 2f426812e5b03545762532751f434e/rootfs/sys/fs/cgroup: no such file or directory</p>
  
  <p>I am trying to install and run Docker on a Oracle Linux machine. I have followed the instructions on the Oracle webpage (<a href="https://docs.oracle.com/cd/E37670_01/E37355/html/section_kfy_f2z_fp.html" rel="nofollow">https://docs.oracle.com/cd/E37670_01/E37355/html/section_kfy_f2z_fp.html</a>), but had some problems.</p>
  
  <p>When installing the docker-engine I had some dependencies problem with the UEK packages, but I could solve those with the instructions on this page (<a href="https://docs.oracle.com/cd/E37670_01/E37355/html/ol_obtain_uek.html" rel="nofollow">https://docs.oracle.com/cd/E37670_01/E37355/html/ol_obtain_uek.html</a>).</p>
  
  <p>The docker-engine seemed to run just fine, but when I try to run the hello-world container I got an error:</p>
  
  <pre><code>[root ~]# docker run hello-world

  <p>Can anybody help me with this?</p>
  
  <p>My knowledge on both Linux and Docker are quite few, so if I forgot to mention any important information please ask!!=o)</p>
