non-ovirt node as gluster node
Hi guys, I have 3 machines that I'd like to test oVirt/gluster on. The idea is that I want two of them to be oVirt nodes and the third to run the oVirt engine. They all have 8 hdd's, and I'd like to use these in gluster for storing the vm images. (on all 3 machines) So, machine1 is a gluster server with oVirt engine installed machine2 is a gluster server and oVirt node machine3 is a gluster server and oVirt node Is this doable?

Usually you´d want to deploy oVirt/Gluster "hyperconverged"[*] with three machines. Hyperconverged means that the servers are deployed both for compute and storage at the same time, and the engine is a VM in it´s own cluster (it doesn´t have to be a separate server). Or is this something you really don´t want? If so, why? [*]: https://ovirt.org/documentation/gluster-hyperconverged/Gluster_Hyperconverge... /K

Machine1 only has a very limited amount of RAM, so it's not usable as a node. And I'd like to keep the engine outside, at least for now. /tony -- -- Tony Albers Systems Architect Systems Director, National Cultural Heritage Cluster Royal Danish Library, Victor Albecks Vej 1, 8000 Aarhus C, Denmark.

OK, no that is not supported. I mean, it was a long time ago but not any more. I wouldn´t worry about the engine being a VM, it´s acutally very stable, net positive compared to having it physical, in my opinion. And more available compared to having hardware outage. What I would do is set it up as three node hyperconverged and then just remove "Machine1" from the "Hosts" interface, so it´s not used for compute. /K

Tony, is there a reason why you wouldn't just do a three more hyper converged setup with self hosted engine? This is the best option for a three server setup imo On Tue, Nov 6, 2018, 8:37 AM Tony Brian Albers <tba@kb.dk wrote:

Quick question on this: is there a solution/procedure to get from a standard installation to a hyper converged one ? Like if I have 3 servers with local-storage and one external engine managing all of them; is there a step-by-step procedure to move to hyper converged ? Simon

You can convert the 3 servers to run both gluster and compute by enabling gluster service on cluster and reinstalling the hosts one at a time (to ensure the gluster packages are installed and gluster is peer probed) However, I don't know if there's a way to move the external engine to hosted engine in this setup.
