Hello,

I can't seem to install the self-hosted engine onto local storage. It gives me glustefs, iscsi, fc, and nfs as the available options. I'm using this in a home-lab scenario, and don't have budget/etc. for building out a dedicated NAS for it, or setting up multiple nodes. I like the look of oVirt, and wanted to try it with a couple disposable vm's (plex, and a docker instance I break often). My current best-thought for how to make it work is to setup NFS on the server, and then point the self-hosted engine at the (local) NFS share. Is there a better way to do this that I might be overlooking?*

*Factoring that I don't have the funds to build out a proper storage environment, yet.

(and if anyone asks, I did search for a solution to this, but didn't find anything super helpful. Mostly I found 5+ year old articles on a similar but different scenario).


You can run an hyperconverged infrastructure where you actually have only one node connecting via gluster to itself.
Now it is fully supported and no need to use the workaround of having NFS running locally

Main upstream doc here:
https://www.ovirt.org/documentation/self-hosted/chap-Deploying_Self-Hosted_Engine.html

Main downstream doc with more details here:
https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure_for_virtualization/1.6/html/deploying_red_hat_hyperconverged_infrastructure_for_virtualization/index

deployment workflow here:
https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure_for_virtualization/1.6/html/deploying_red_hat_hyperconverged_infrastructure_for_virtualization/deployment_workflow

and after initial host configuration steps you will arrive at the step of cockpit configuration where you choose the "Hyperconverged" option (at the right) and then button "Run Gluster Wizard For Single Node":
