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

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.

Recent developments concerning Ceph in oVirt are disappointing for me, I think I will have to look elsewhere (OpenStack, Proxmox) for our rather big deployment. At least Nir Soffer's explanation for the move to cinderlib in another thread (dated 20210121) shed some light on the background of this decision. Matthias
