Hi community!
I have issue when trying to restore 4.3.10.4 hosted engine.
hosted-engine --deploy --restore-from-file=/opt/engine-backup.dump If I not use --restore-from-file I can not correctly restore my hosted engine datacenter and cluster. But another DCs restored fine.
If the source engine machine has DWH DB on the engine machine, provisioned automatically by engine-setup, then above should not fail. If it does, it might be a bug. Please check/share relevant logs. Thanks.
[ ERROR ] Failed to execute stage 'Environment setup': Cannot connect to DWH database using existing credentials: ovirt_engine_history@localhost:5432
I know that i can fix problem by editing PostgreSQL pg_hba.conf and set ACLs to trust. Is any way to customize hosted engine appliance to replace pg_hba.conf to my version? Is any way to pause deploy proccess and access to hosted engine VM to edit PostgreSQL config?
Yes, you can place a "enginevm_before_engine_setup" hook, it will be ran before engine-setup. Good luck and best regards, -- Didi

Great, but I can't find the example file in my installation /usr/share/ovirt-hosted-engine-setup/ansible/hooks/enginevm_before_engine_setup/enginevm_before_engine_setup.yml.example. Is there any documentation to engine setup hooks?
Good luck and best regards,

That's not enough - please check/share all files there. Thanks. From the log, it seems like dwh db was not included, which probably means that it was either remote (dwh on a separate machine) or you passed '--scope=files --scope=db' when taking the backup. If latter: 1. Where did you find instructions to do this? This should be fixed. 2. Please try again, either without --scope, or with --scope=all, or '--scope=files --scope=db --scope=dwhdb'. If it's former (dwh+its db are on a separate machine), then the documentation is not yet up-to-date - please see also: https://bugzilla.redhat.com/show_bug.cgi?id=1874904

I am only aware of: https://github.com/oVirt/ovirt-ansible-collection/tree/master/roles/hosted_e... The code moved there recently - before that, it was in: https://github.com/oVirt/ovirt-ansible-hosted-engine-setup There are a few examples scattered around the net, in this mailing list, bugzilla, etc. One I wrote myself recently is "required_networks_fix.yml" mentioned there (and included inside examples/).

From the log, it seems like dwh db was not included, which probably means that it was either remote (dwh on a separate machine) or you passed '--scope=files --scope=db' when taking the backup.
Wow, the --scope=files --scope=db parameters were actually used. The worst thing is that the internal wiki has the correct parameter "--scope=all". I'll try to perform the backup again and redeploy engine. Many thanks.
If latter:
1. Where did you find instructions to do this? This should be fixed.
Well, I suspect that this link was mistakenly used https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine... (Migrating the Self-Hosted Engine Database to a Remote Server -> 3. Create the engine database backup)
2. Please try again, either without --scope, or with --scope=all, or '--scope=files --scope=db --scope=dwhdb'.
