<div dir="ltr">Hi Sahina and Yedidyah,<div><br></div><div>Thanks for the information and offers of help. I am pleased to report that I've resolved the issue I had, thanks to the prompting your requests gave me, and everything is functional. I shall attempt to explain what happened and how I fixed it.</div><div><br></div><div>When I looked at the Gluster peer status, the Host01 was rejected by Host02 and Host03 (I did check this back at the start, but didn't check it again and things had changed). I followed the Gluster docs to fix the rejected peer (<a href="http://gluster-documentations.readthedocs.io/en/latest/Administrator%20Guide/Resolving%20Peer%20Rejected/">http://gluster-documentations.readthedocs.io/en/latest/Administrator%20Guide/Resolving%20Peer%20Rejected/</a>).</div><div><br></div><div>This then gave me a different error message when trying to add Host02 or Host03, "no available server in the cluster to probe the new server", which only further confirmed that it was a Gluster issue, as was suggested.</div><div><br></div><div>After some hair-pulling and wondering, I finally discovered that, in Compute > Hosts > Host01 under the General tab, it was complaining that Gluster was not active (even though it was running). I clicked the action item link to resolve that, and oVirt appeared to start actually managing the Gluster service. I could then add my other hosts, import the existing storage domains, and everything appears good now.</div><div><br></div><div>Thanks again for the assistance and prompting me towards the right places to help me resolve it.</div><div><br></div><div>Regards,</div><div>Adam</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr">On Thu, 22 Mar 2018 at 20:48 Sahina Bose <<a href="mailto:sabose@redhat.com">sabose@redhat.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote">On Wed, Mar 21, 2018 at 12:33 PM, Yedidyah Bar David <span dir="ltr"><<a href="mailto:didi@redhat.com" target="_blank">didi@redhat.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span>On Wed, Mar 21, 2018 at 8:17 AM, Adam Chesterton<br>

</span>If it's only about hosted-engine, you can check /etc/ovirt-hosted-engine .<br>
<br>
You might try using ovirt-hosted-engine-cleanup, although it was not designed<br>
for such cases.<br>

<br>
</span>If you do not need the data, a reinstall might be simplest.<br>
If you do, not sure what's your exact plan.<br>
You intend to rely on the replication? So that you reinstall one host, add it,<br>
wait until syncing finished, then reinstall the other? Might work, no idea.<br>
<br>
