Ceph support is available via Managed Block Storage (tech preview), it cannot be used instead of gluster for hyperconverged setups.
Moreover, it is not possible to use a pure Managed Block Storage setup at all, there has to be at least one regular storage domain in a datacenter On Mon, Jan 18, 2021 at 11:58 AM Shantur Rathore <rathor...@gmail.com> wrote: > > Thanks Strahil for your reply. > > Sorry just to confirm, > > 1.
