Re: Move Self Hosted Engine to Standalone
by Jeremy Tourville
I did get a little further.
First I ran engine-cleanup on my new engine where I will be running the restore operation. (I had previously run the engine-setup script on this machine)
Then I ran this-
[root@engine ~]# engine-backup --mode=restore --file=ovirt-engine-backup-20200217125040.backup --log=ovirt-engine-backup-20200217125040.log --provision-db --provision-dwh-db --restore-permissions
Start of engine-backup with mode 'restore'
scope: all
archive file: ovirt-engine-backup-20200217125040.backup
log file: ovirt-engine-backup-20200217125040.log
Preparing to restore:
- Unpacking file 'ovirt-engine-backup-20200217125040.backup'
Restoring:
- Files
Provisioning PostgreSQL users/databases:
- user 'engine', database 'engine'
FATAL: Existing database 'engine' or user 'engine' found and temporary ones created - Please clean up everything and try again
Time to research further for that FATAL error message. Isn't that the purpose of engine-cleanup though? Why the conflict?

OK, I was able to get the backup completed. I am a little confused on how to do the restore though. https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Resto...
Is this link even applicable? My environment is a single node, not EL based. Anyhow, here is what I have so far-
[root@engine glusterfs]# engine-backup
Start of engine-backup with mode 'backup'
scope: all
archive file: /var/lib/ovirt-engine-backup/ovirt-engine-backup-20200217125040.backup

- DWH database 'ovirt_engine_history'
Packing into file '/var/lib/ovirt-engine-backup/ovirt-engine-backup-20200217125040.backup'
Notifying engine
Done.
[root@engine glusterfs]#
I moved the backup file to my new engine.
How do I perform the restore?
The directions say:
# engine-backup --mode=restore --file=file_name --log=log_file_name --provision-db --provision-dwh-db --restore-permissions
What is the file name and log_file name? Do I need to do something to unpack my backup file?

oVirt & Zabbix agent
by Diggy Mc
Are there any known issues with running the Zabbix agent on either the Hosted Engine (4.3.8) or oVirt Nodes (4.3.8) ??? I'd like to install the agent while not crashing my hosting environment.

hosted-engine --deploy --restore-from-file fails with error "Domain format is different from master storage domain format"
by djagoo
Hi there,
for two weeks we are trying to move our hosted engine to a glusterfs storage resulting in an error "Domain format is different from master storage domain format".
The newly created storage domain has version 5 (default since compatibility level 4.3 according to documentation).
Hosted engine version is 4.3.8.2-1.el7
All hosts are updated to the latest versions and are rebooted.
Cluster and DataCenter compatibility version is 4.3.
Master data domain and all other domains are Format V4 and there is no V5 available in dropdown menus. Even if I try to create a new storage domain from manager there is only V4 available.
The system and all hosts where installed march 2019 so it was ovirt release 4.3.2 or 4.3.1 which created the existing domains.
Is there a way to update the master storage domain to V5? It seems I cannot downgrade the datacenter to compat 4.2 and then raise it again.
After two weeks I'm out of ideas.
Can anyone help please?
Regards,
Marcel

by adrianquintero＠gmail.com
Hi am trying to upgrade our ovirt hosts and engine in our Hyperconverged 4.3.6 environment to 4.3.7, we do not want to go to 4.3.8.
Where can I find the correct repositories for 4.3.7 specific to the engine and the ones for the hosts?
Thank you
