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 _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users

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.

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.

There should be a main tab called 'Volumes' which is present. Are you not seeing that? I have attached screenshot for the same.
