As we have tested off the list, it seems that the symbolic link in /var/lib/vdsm that
ovirt-ha-agent/broker create was missing.
Yet migration succeeds, but the donor host looses score as the vm 'died
unexpectedly'.
Try to cleanup the host2's metadata and try to provision it , so you can proceed with
the fix of host1 & host3.
I have no clue if engine-cleanup will affect the shared syorage, but it's possible -
so use as last resort.
'engine-cleanup' is a utility you run on the engine machine, which
does basically the opposite of 'engine-setup', and in any case cleans
up the _engine_, not any particular host. If you run it, your engine
is gone, likely forever (unless you kept backups).
What you might were looking for is 'ovirt-hosted-engine-cleanup'. This
one cleans up a host from a hosted-engine deployment. It's generally
intended to be used after a failed deployment attempt. I think it can
work well also in your case, but would first try to fix using other
means.
If you fail to add host2 , you can always reinstall it as host4 and try to add it fresh.

Dear oVirt,
I have already reached out twice regarding the issues that occurred, due to power outage,
but noticed only when upgrading engine to latest 4.3. version.
I am unable to redeploy engine on Host2, the hosted-engine file stays empty and VDSM on
Hosts1 and 3 is reporting, even though I cleared the metadata for the Host2, on Host 1 and
Host3:
2021-04-30 05:57:58,454-0700 ERROR (jsonrpc/7)
[ovirt_hosted_engine_ha.client.client.HAClient] Malformed metadata for host 2: received 0
of 512 expected bytes (client:137)
Today I tried to migrate HE from Host 3 to Host 1 and it fails each time with following
message:

I know that this version is end of life – but I would very much appreciate if someone
could help me asses if this means corruption in DB or the overall damage, simply to know
how to plan further actions.
My impression was that I still had to functional HE Hosts in the pool, but after seeing
migration failure, it’s pretty much down to single host.
This is production system, so I cannot just move on to upgrading/deploying to 4.4.
Additionally – :
Is the effect of the engine-cleanup on HE Host local or it affects all HE Hosts? Could
that help bringing the Host back to state so that HE can be re-deployed?
What is the effect or reinitialize-lockspace?
Kindly awaiting your reply. Happy to provide any additional information needed.
