[ovirt-users] Re: Managed Block Storage and more

Thanks Strahil for your reply. Sorry just to confirm, 1. Are you saying Ceph on oVirt Node NG isn't possible? 2. Would you know which devs would be best to ask about the recent Ceph changes?

Yet, you can add as many as you wish as a compute node (won't be part of Gluster) and later you can add them to the Gluster TSP (this requires 3 nodes at a time). > > 4.
