    Hi,<br>
    so i was running a 3.4 hosted engine two node setup on centos 6, had
    some disk issues so i tried to upgrade to centos 7 and follow the
    path 3.4 &gt; 3.5 &gt; 3.6 &gt; 4.0.  i screwed up dig time
    somewhere between 3.6 and 4.0, so i wiped the drives, installed a
    fresh 4.0.3, then created the database and restored the 3.6 engine
    backup before running engine-setup as per the docs.   things seemed
    to work, but i have the the following issues / symptoms:<br>
    - ovirt-ha-agent running 100% CPU on both nodes<br>
    - messages in the UI that the Hosted Engine storage Domain isn't
    active and Failed to import the Hosted Engine Storage Domain<br>
    - hosted engine is not visible in the UI<br>
    and the following repeating in the agent.log:<br>

    I have searched a bit and not really found a solution, and have come
    to the conclusion that i have made a mess of things, and am
    wondering if the best solution is to export the VMs, and reinstall
    everything then import them back?<br>
    i am using remote  NFS storage.<br>
    if i try and add the hosted engine storage domain it says it is
    already registered.<br>
    i have also upgraded and am now running <span
      class="gwt-InlineLabel">oVirt Engine Version: 4.0.4.4-1.el7.centos<br>
      hosts were installed using ovirt-node.  currently at 
      3.10.0-327.28.3.el7.x86_64<br>
      if a fresh install is best, any advice / pointer to doc that
      explains best way to do this?<br>
      i have not moved my most important server over to this cluster yet
      so i can take some downtime to reinstall.<br>
      thanks!<br>
