ceph (and anything supported by cindelib) is available via Managed block storage: https://www.ovirt.org/develop/release-management/features/storage/cinderlib-integration.html > So now I'm thinking about switching gears, and going with iSCSI instead. > But I'm still trying to think about the best way to replicate the storage, > and possibly use multipathing so that it will be HA for the VMs that rely > on it. > > Has anyone else experienced problems with the Gluster hyperconverged > solution?
