Hi,

Is it technically possible to install openstack tripleO on 3 nodes, such that all 3 nodes play the roles of controller compute and ceph storage (hci) at the same time, with replication and HA and all?

I think it could be done by creating a custom role which merges the Controller and ComputeHCI services together but it has important implications; for example, should pacemaker fence a node, that would kill the workload *and* the osds hosted on that node this can be acceptable or not, depending on expectations and other possible mitigations I guess -- Giulio Fidente GPG KEY: 08D733BA
