configuring gluster volumes/bricks from ovirt ??

hi, i'm trying to get into this gluster thing with oVirt and added a 2 node gluster cluster to my oVirt 4.1 data center (just for testing, i know it can't have HA with 2 nodes). provisioning of the storage hosts did apparently work and my storage cluster seems to be operational. i have very little understanding of glusterfs right know, but what i think i am missing in the interface is a way to configure volumes/bricks on my gluster cluster/hosts so i can use them for storage domains (i want to use a "managed gluster volume"), the drop down "Gluster" in "New domain" is empty. all i could find for storage specific UI was the "Services" tab for the storage cluster which is empty. i'm not using a hyperconverged/self-hosted setup, my engine is located on a dedicated server and i used iSCSI storage for data master domain. my hosts (for hypervisors and gluster storage) where installed on top of centos7, not using oVirt Node. does my setup make sense (it's only for testing)? do i have to configure gluster hosts manually? do i need more than 2 storage hosts when i want to configure gluster with ovirt (in hyperconverged setup 3 hosts are mandatory)? do i need oVirt Node/cockpit on the storage hosts to do further configuration? thanks a lot for reading matthias

yes, you will have to do this manually .
do i need more than 2 storage hosts when i want to configure gluster with ovirt (in hyperconverged setup 3 hosts are mandatory)? It is always recommended to have 3 hosts as we say that in replica 3 volumes there is less / no chance to see split brain issues. For hyper converged setup 3 hosts are mandatory. do i need oVirt Node/cockpit on the storage hosts to do further configuration? you can reduce the pain of configuring gluster hosts manually if we cockpit on centos7 / Ovirt Node.

yes, you will have to do this manually . Installing gluster packages have to done manually. Once gluster packages are installed you can create a gluster cluster from ovirt UI , add gluster hosts and create volumes on them using the volumes tab.

i'm sorry, but i'm missing all these "Gluster Volumes" UI components that are mentioned in http://www.ovirt.org/develop/release-management/features/gluster/gluster-sup.... the tabs i see for my storage cluster are "General", "Logical Networks", "Hosts", "Services", "Permissions". as i said "Services" is empty, is that a problem? what's wrong? thx matthias

Does your cluster has both virt+gluster enabled or only virt ? If only virt you will not be able to see them. If the cluster has both virt+gluster service enabled or only gluster service enabled you should be able to see them.

I think you have selected the cluster and you are referring to the sub tabs for that cluster. There should be a main tab called 'Volumes' which is present. Are you not seeing that? I have attached screenshot for the same.

thanks for the screenshot, now i know how it should look like. i'm attaching my screenshot. i'm missing a couple of elements, especially "Cluster Node Type" (i don't have that in my VM cluster either). is there an obvious explanation? next step would be to recreate the gluster cluster with "clean" oVirt Nodes. maybe my storage hosts are botched, i had glusterfs 3.10 packages installed on one of them previously thanks a lot so far matthias

no, i didn't... (didn't know what i was doing then) i'm learning it the hard way... going to start again from scratch... still i think oVirt is a great product, thanks for software and support ;-) matthias
