> Which nightly backups? Do they run engine-backup? Yes sorry. The backups are the backups created when running the engine-backup script. So I have the files and the DB backed up and off onto different storage. I just grabbed a copy of the entire /etc directory as well just in case there was something needed in there that is not included in the engine-backup solution.

My plan is to get a new server ordered and built, removing the old server from the equation (old server is old and needs to be replaced anyway). Then rebuild the Ovirt bits and restore the data from my backups. I just more needed a quick set up steps to take here. From what I gather I need to basically: 1. reinstall CentOS 2. Reconfigure storage (this server has several ISCSI LUNs its attached to currently. I don’t know if they are required for this or what). 3. Install PostGreSQL (maybe? Or does the ovirt engine script do this for you?) 3. Install Ovirt/run ovirt-engine script maybe? 4. Restore DB and data I am not sure the details of the list outlined above (what to run where, etc.). I am looking for consultants to help me out here as its clear I am a bit behind the curve on this one. So far not much has worked out on that front. Does the above list seem reasonable in terms of needed steps to get this going again? -----Original Message----- From: Yedidyah Bar David ([email protected]) <[email protected]> Sent: Sunday, December 22, 2019 1:58 AM To: [email protected] Cc: users <[email protected]> Subject: [ovirt-users] Re: OVirt Engine Server Died - Steps for Rebuilding the Ovirt Engine System On Fri, Dec 20, 2019 at 8:55 PM <[email protected]> wrote: > > Full disclosure here.....I am not an Ovirt Expert.

Generally speaking, if you used engine-backup for backups, it should be enough - it backs up all it needs from /etc. If you didn't use that, /etc won't be enough. You also need a database backup. If you do not have a backup of the database, you'll need to create a new engine from scratch. You can then import the existing storage domains and add the hosts. This will require downtime, and you'll loose some stuff, so if you do have an engine-backup backup, better use that. In either case, assuming this is a production env, I suggest to first test on a separate env to see how it all looks like. > Also, until I can get the engine running again, is there any tool available > to manage the VMs on the hosts themselves.

It's much less than what the engine allows. If you search the list archives, you can find suggestions by people to directly use libvirt/virsh after poking a bit inside your storage domain. I'd not recommend doing that, unless you know very well what you are doing and have no other solution (e.g. if storage is corrupted enough so that import to a new engine fails). > Any info on this as well as what to backup and the steps to move the engine > from one server to another would be much much appreciated. You can search the site for backup, restore, and import storage domain, and should find the relevant pages. Please note that the pages under /develop are written during development and are usually not updated after a feature is complete. The official documentation is under /documentation. That, in turn, is often outdated as well :-(. You can use RHV docs in addition. These are more up-to-date and should be 99% applicable to oVirt. > Sorry I know this a real RTM type post but I am in a bind and need a solution > rather quickly. Thanks in advance.
