OVIRT Engine Restore from old Backup
by Abe E
Hey All, I really dont like spamming the forums but the issues I am having keep changing entirely.
I am at the point where I can get much closer to rebuilding my engine although my hurtle currently is restoring.
When I restore using my most recent backup it is problematic
Currently I am restoring by:
clean engine install
engine-cleanup
engine-backup --mode=restore --file=ovirt-engine-backup-20220504011012.backup --log=restore5.log
engine-setup
Comes up with alot of annoyances as the ID of the old hosted_storage and the new one are mismatched in the GUI.
On top of that it is not allowing me to deploy the engine to the 2nd Gluster (3rd one keeps deleting its glusters on reboot since 4.3 Upgrade).
Host 1 which runs the hosted engine is not showing as active or unlike, rather it is unresponsive, when I tried to enroll certificates it finally accepted but failed because it said its missing networks, once added it crashed the engine and ha agent wouldnt come up. Now that I think of it, I could have removed the extra networks from being required although it still doesnt benefit me here as I am unable to deploy or reinstall the 2nd Gluster node and the first one will not show its correct state as the host.
Should I just be deploying the DB, or is the full file backup fine? My issue here is it takes long to redeploy so the trial an error of failing takes me hours as my backup is from 4.5 engine even though my nodes are on 4.4 as 4.5 keeps causing the catastrophic failure of my whole cluster.

FC Storage recover
by csabany＠freemail.hu
Hi,
We have a 4 node cluster (4.4.10) and a standalone manager.
We attached to this cluster 4 volumes on FC.
Last week we lost the storage canisters (both), but recovered one of them from the storage disks.
Unfortunatly only 3 storages came back from offline.
I see the 4th FC ID, but it's on "Can't Extend" status.
If i check the storages on nodes (lsblk), i can see only the ID not more on this 4th storage.
Do you know any recovery tool or any idea for this situation?
Thanks

OVA Export from Snapshot?
by Alan G
Hi,
Is there a way to export an OVA from a snapshot? Or only from the "Active VM" image?
Thanks,

CLI Offline Engine Deployment failing to activate storage domain to gluster error 400
by Abe E
Due to some complications in my 4.4 to 4.5 upgrade that have taken down ovirt for a few days I must go back to 4.4 to salvage what I can and rethink how I will upgrade.
Due to that im having to rebuild my engine although I took backups prior.
My issue currently is with 4.4 the engine deployment has an error regarding mirrors so I was able to use the ansible script to deploy offline and I am at the activate storage domain portion where it fails
I am setting it to glusterfs with the host:/path as gluster-1.d.com:/engine
The host machine i am building the engine on has a mount:
gluster-1.d.com:/engine 104804356 13827696 90976660 14% /rhev/data-center/mnt/glusterSD/gluster-1.d.com:_engine
within the mapping :
drwxr-xr-x. 2 vdsm kvm 6 Apr 5 22:15 gluster-1.d.com:_data
drwxr-xr-x. 4 vdsm kvm 38 May 5 15:00 gluster-1.d.com:_engine
I am able to get into the temp engines ssh and ping the domain although I cannot seem to find where my steps are incorrect.

Backing up VMs with qemu-img
by David White
I've recently been working with the qemu-img commands for some work that has nothing to do with oVirt or anything inside an oVirt environment.
But learning and using these commands have given me an idea for automating backups.
I believe that the following is true, but to confirm, would the qemu-img commands be available on the oVirt hosts to take VM snapshots and disk images?
