Hi,
I have problem with LOCKED host after restore of engine.
i am trying many disaster scenarios and one from them is loosing of all hosts with self
hosted engine included with backup file of engine only.
When all hosts and engine VM were destroyed at the same time, i installed new self hosted
engine on hardware from one lost host. Then tried restore engine
engine-backup --mode=restore --scope=all --file=backup/file/ovirt-engine-backup
--log=backup/log/ovirt-engine-backup.log --no-restore-permissions --provision-db
--provision-dwh-db –provision-reports-db
After this, lost engine was restored successfully. I had offline Datacentrer, dead hosts
and VM. I added new hosts, which were able to connect to domain storage automatically and
I was able to start VM.
New host cannot has the same IP as already dead host or hardware UID. This can be solved
by setup old dead host to maintenance mode and then delete host. Then the same hardware
and IP can be reused.
But, host where old engine was running is LOCKED. You cannot migrate engine VM, cannot
start hosted engine from new engine GUI, cannot setup host to maintenance mode and
delete.. This is problem when your hardware for hosts is limited.
I would like to ask how to solve this situation, Is there any way how to “reinstall” old
hosts? I see that SSL certificates were changed with new installation of new hosts, but I
don’t know if there is way how to enable old dead hosts.
Is there any way how to destroy old engine VM to add host back to work ?
Thank you

New subject: all hosts lost scenario - restore engine from backup file - LOCKED HOST 4.3 version
Why don't you use 'hosted-engine --deploy --restore-from-file=' ?
