Hi! We had a power outage and all our servers (oVirt hosts) went down. When they started up neither the hosted-engine nor VMs were started. hosted-engine --vm-status says: You must run deploy first I tried running deploy with various options but ultimately get stuck at: The Host ID is already known. Is this a re-deployment on an additional host that was previously set up (Yes, No)[Yes]? ... [ ERROR ] Failed to execute stage 'Closing up': <urlopen error [Errno 113] No route to host> OR The specified storage location already contains a data domain. Is this an additional host setup (Yes, No)[Yes]? No [ ERROR ] Re-deploying the engine VM over a previously (partially) deployed system is not supported. Please clean up the storage device or select a different one and retry. NOTES: 1. This is oVirt v3.6 (legacy install, I know...) 2. We do have daily engine backups (.bak files) [till the day the power failed] Any advice/assistance appreciated. Thanks! Roderick

Hello and thanks for assisting! I think I may have found the problem :) /etc/ovirt-hosted-engine/hosted-engine.conf is blank. But I do have hosted-engine.conf~ Can I cp this to restore the original? Anything else I need to do?

Hi, Somehow related to the power being "pulled" at the wrong time? Not sure what does it but I'm glad it did ;) I had to restore one of my hosts (host 1) manually due a cleanup during my re-deploy attempts. I managed to do this successfully by copying the missing files from another host (host 2) but the first time the host ID matched one of the other hosts (which made at least hosted-engine --vm-status unhappy) [I hadn't seen your email yet :(]. I subsequently corrected the host_id and rebooted the guilty host. Things mostly seem to be working now except that in hosted-engine --vm-status my first two hosts (the one I copied the .conf from as well as the one I copied it to [without changing the ID :O]) now have the same hostname :-/ I'm assuming there's a mismatch in the engine database - where/how do I fix that?

Thanks, Not seeing duplicates in the web UI, only in the --vm-status. Can you please assist me with the sql commands or reference to the database schema + where to check? I'd like to check that first before doing anything too drastic. Note: it only duplicated the hostname after I changed the host_id, before that it had the correct hostname but duplicate host_id. PS I have a recent backup of the database (just before which I could restore if you think that'll do the trick without breaking anything?

Hi Didi! Ok, I started the clean metadata process and then found the real issue - I had copied the certs (just /etc/pki/vdsm; other pki folders were intact) from a working host (host 2) to host 1 following the re-deploy cleanup as part of the process to get it online again. The problem is the cert contains the hostname (so now the cert on host 1 contains as Subject CN the hostname of host 2). I found some docs on the certs for libvirt but it's not clear what I need to do to correctly re-generate the vdsm certs on host 1. Can you help? PS I presume I need to re-generate client certs for that host as well and copy to the engine?

Thanks so much, this worked! For the record/list benefit, I first put the host into maintenance and then selected Enroll Certificate - this regenerated the certs. (VDSM cert can be checked with: certtool -i --infile /etc/pki/vdsm/certs/vdsmcert.pem) I then took these steps on the affected (incorrectly reported) host to update the hosted-engine --vm-status: 1. hosted-engine --set-maintenance --mode=global 2. systemctl stop ovirt-ha-agent.service 3. hosted-engine --clean-metadata 4. systemctl start ovirt-ha-agent.service 5. hosted-engine --vm-status (after a minute or two - to verify that the host details are now correct) Cheers :) On 2021/02/04 10:17, Yedidyah Bar David wrote: > On Thu, Feb 4, 2021 at 10:09 AM Roderick Mooi <roderick(a)sanren.ac.za&gt; wrote: >> >> Hi Didi! >> >> Ok, I started the clean metadata process and then found the real issue - I had copied the certs (just /etc/pki/vdsm; other pki folders were intact) from a working host (host 2) to host 1 following the re-deploy cleanup as part of the process to get it online again.
