Thanks Matthias, Ceph iSCSI is indeed supported but it introduces an overhead for running LIO gateways for iSCSI. CephFS works as a posix domain, if we could get a posix domain to work as a master domain then we could run a self-hosted engine on it. Ceph RBD ( rbd-nbd hopefully in future ) could be used with cinderlib and we have got a self-hosted infrastructure with Ceph.
I am hopeful that when cinderlib integration is mature enough to be out of Tech preview, there will be a way to migrate old cinder disks to new cinderlib. PS: About your large deployment, go OpenStack or OpenNebula if you like. Proxmox clustering isn't very great, it doesn't have a single controller and uses coro-sync based clustering which isn't very great.
