Hi,
Any idea how this happened?
Somehow related to the power being "pulled" at the wrong time?
Perhaps this is a backup done by emacs?
Not sure what does it but I'm glad it did ;)
Please compare it to your other hosts. It should be (mostly?) identical, but make sure that host_id= is unique per host. It should match the spm host id for this host in the engine database.
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? Appreciated! (and happy cos our cluster is almost back to normal :) ) On 2021/02/03 11:30, Yedidyah Bar David wrote:

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?
Not sure, but better find the root cause to make sure no other damage was done.
Good luck,
Appreciated

Usually,
I would start with checking the output of the /var/log/ovirt-hosted-engine-ha/{broker,agent}.log
I'm typing it on my phone, so the path could have a typo.
Check if the following services (also typed by memory, might have to remove the 'd') are running: - sanlock - supervdsmd - vdsmd
Sometimes, some of my VGs (gluster) are not activated, so if you run hyperconverged -> you can 'vgchange -ay'.

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!
