19.03.2019 on the server with the ovirt engine, I reinstalled the GUI and it seemed to delete the ovirt-engine, in any case, the installed ovirt-engine packages were not. I reinstalled the ovirt-engine package, but could not connect to the web interface. There are such errors in the /var/log/ovirt-engine/engine.log:

ovirt-engine-4.2.8.2-1 CentOS 7, 3.10.0-693.2.2.el7.x86_64

I have a backup file, but version 4.1. Recovering from it using engine-backup is impossible. I also have a backup /etc before deleting the ovirt-engine.

Как мне восстановить ovirt-engine?

Please provide more details. What exactly did you do? If it's something like: yum install ovirt-engine engine-setup yum remove ovirt-engine yum install ovirt-engine then: 1. Recovering from that is not supported nor tested, so take the following with a grain of salt. 2. The biggest damage from 'yum remove' is removal of pki. You should find a backup, though, in /etc/pki/ovirt-engine-backups/something. You can try to restore that to /etc/pki/ovirt-engine and see what happens. 3. You can also simply try running 'engine-setup'. It should recreate pki. This will also then require reinstalling all hosts (or at least "Enroll Certificate"). 4. Alternatively, you can try using your 4.1 engine-backup. Best way is by installing 4.1, restoring the backup, then upgrading. Alternatively, you can patch engine-backup to not refuse restoring the older version, see e.g. https://bugzilla.redhat.com/show_bug.cgi?id=1425788 . 5. Alternatively, you can compare your current /etc with the backup you took, and carefully decide which files should be restored. Then you can try running 'egnine-setup' and see what happens. Obviously, this is the best option in terms of chances for success, but is also the most time-consuming. Good luck and best regards, -- Didi
