[ovirt-users] Re: Reimport VMs after lost Engine with broken Backup

Once again bumping my own thread. I came across this link: https://www.ovirt.org/develop/release-management/features/storage/imports... So it’s say that the VM metadata is stored in OVF_STORE. Which is awesome. But in my case right now, the VM’s are running. So I need to properly shutdown them (I can SSH to all of them and them issue power off). But I can’t detach the storage from the broken engine. * Is it safe to just attach the storage domain on the brand new engine? If it fails there’s a way to recover from this? Thanks.

But I was able to recover the backup, but it ended in a non usable state. The process was reinstall a host from the DVD. Create a new NFS share to the new hosted engine and do the ovirt-hosted-engine-setup procedure. After the new engine is up, I’ve connected to it via SSH and run engine-backup to restore my old backup. After that the engine is up, but this new engine does not knows he is hosted and the interface still shows the old one down. So right now, all my VM’s are running on ovirt2 and in ovirt1 there’s the new hosted engine. On the interface the old still appears: <PastedGraphic-1.png> The ovirt1 host can’t join since it complains about SSL Errors: VDSM ovirt1 command Get Host Capabilities failed: General SSLEngine problem, and the status is unassigned. I can’t do nothing on it: <PastedGraphic-2.png> So… I’m still considering recreating everything from the ground, the real issue will be re adding the VMs. So the original question is still valid: What happens if I just add the ovirt2 machine to the new engine? It will reboot or will add everything back: storage, networks etc? Thanks, Vinícius.

For reasons unknown the backup is broken and I’ve tried everything: redeploy with backup file, deploy a new one and them restore the backup. Changed the HE storage domain in both cases just be sure. Reinstalled one of the hosts just to be safe but nothing worked. So I just deployed a brand new engine and now I want to import back the VM’s. My scenario right now is: ovirt1 brand new with the new VM in a new storage domain. ovirt2 have production VMs running without any issue. So my questions right now: * What happens if I just add the ovirt2 machine to the new engine? It will reboot or will add everything back: storage, networks etc? My plan right now would be: * Reconfigure the DC and the cluster. * Readd all the networks. * Reattach the storage domains. * Recreate all the VM”s attaching it’s disks. Is there’s something that I can do better to mitigate the work? Thanks,
