[Users] Ovirt engine high availability
Hello, Was wondering if anyone can shed a light on this subject as I could not find any documentation specific to this. I am currently running an ovirt 3.2 cluster with 5 hosts with local storage. I have a dedicated box running ovirt engine. I would like to have the ability to run an additional box with ovirt engine on it for high availability of the portal. I realize this would most likely require I run a separate instance of postgres for the engine, however I was wondering if this is something that is officially supported? Thanks!

There are plenty of options: 1. Run the engine as a VM under a local libvirt, and cluster the libvirt VM as a protected service using RHCS (well tested and documented) 2. Use the self hosted engine (recently announced, coming up tech) 3. Use any other clustering technology you like best, an engine VM with a centrally backed storage is very easy to start on any capable host On Wed, Sep 25, 2013 at 10:06 AM, Doug Bishop <dbishop@controlscan.com>wrote:

Those are good options, however since I am not running centralized storage, all my hosts are in their own data center with local storage options only. Thats why I have two standalone machines to run ovirt on. Im guessing this is not recommended? If not is there away to allow local storage and nfs based storage in a data center?

Yeah, that was along the lines of what I was thinking. Just wanted to make sure there wasnt an official way to do it as well. Thanks!

Yes. However we are using it for a dev / qa environments in house. We plan to roll rhev into production soon and will be using backend storage.
