Hi,
will answer myself... but if you have comments or have better solution
please levae comment
ovirt-engine-setup log logs SELECT statements to test global maintenance
state. In my case
engine=# SELECT vm_guid, run_on_vds FROM vms WHERE vm_name =
'HostedEngine';
vm_guid | run_on_vds
--------------------------------------+--------------------------------------
96a6b6a7-75a9-472a-9d4f-1502b415470a |
e24f0dcc-51f3-4d1a-acf5-2833a9dc584a
(1 row)
and
engine=# SELECT vds_id, ha_global_maintenance FROM vds_statistics WHERE
vds_id = 'e24f0dcc-51f3-4d1a-acf5-2833a9dc584a';
vds_id | ha_global_maintenance
--------------------------------------+-----------------------
e24f0dcc-51f3-4d1a-acf5-2833a9dc584a | f
(1 row)
because I believe global maintenance is really enabled I have updated
ha_global_maintenance state with
engine=# UPDATE vds_statistics SET ha_global_maintenance = true WHERE
vds_id = 'e24f0dcc-51f3-4d1a-acf5-2833a9dc584a';
UPDATE 1
after that I run
engine-setup --offline
and choose Renew certificates? (Yes, No) [No]: Yes
after that all hosts becomes up and vms were recovered (except that vms
on failed and restarted host)
Cheers,
Jiri

Hello,
I am stuck in this situation...
It looks like engine certificate (engine.cer) expired few days ago
[root@ovirt ~]# openssl x509 -in /etc/pki/ovirt-engine/certs/engine.cer
-noout -dates
notBefore=Mar 23 21:34:19 2021 GMT
notAfter=Apr 26 21:34:19 2022 GMT
CA and other certs are still valid
Yesterday I had one host outage and HE restarted on other host. But it
cannot communicate with all hosts due to certificate expiration

There are vms still running on hosts.
Is there way how to (manualy?) renew engine cert and recover from this
situation?
I have tried run engine-setup (and select renew certificate during install)
[root@ovirt ~]# engine-setup --offline
but it fails with

In that case you should put the system into the "Global
