Hyperconverged set up with Gluster and 6 Nodes

Dear All, in all documentation to set up oVirt in a Hyperconverged system with Gluster says that it must have 3 Enterprise nodes. In our test environment we set up successfully with oVirt wizard an oVirt cluster with gluster + Arbiter and hosted engine. Is it also possible to build a cluster with 6 nodes? The wizard gives only the option to add 3 nodes. Is this kind of design supported? My idea is, first to set up the Gluster, then install the oVirt nodes and deploy the engine. Would this work? Any documentation avaiable? Thanks Holger

Edit (adding users , so that they can correct me if im wrong , or provide more inputs) Hi Holger, Yes, (someone else correct me if im wrong), it is possible via gluster ansible deployment, and if i'm not wrong , initially you need to deploy the usual 3 node setup and then add then add in further hosts in the sets of 3 ( i believe maximum of 12 nodes is supported) and then create a new gluster volume in the new nodes and then expand the existing nodes to accommodate new disks on the new host. i believe this doc <https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure_for_virtualization/1.6/pdf/automating_rhhi_for_virtualization_deployment/Red_Hat_Hyperconverged_Infrastructure_for_Virtualization-1.6-Automating_RHHI_for_Virtualization_deployment-en-US.pdf> should you give you a little insight:- its a little old but gives you an idea hope this helps!

Prajith, many thanks for your reply. I'll take a look but seems exactly for what I searched. Thanks Holger

You can extend the gluster volume with your extra 3 nodes. Keep in mind that it is good to have 'backup-volfile-servers=node2:node3:node4:node5:node6' in order to allow FUSE to overcome failure of node1.

Strahil, Thanks a lot. You have a documentation about this settings? Thanks Holger
