I'm a bit biased but Rook[0] or OpenEBS[1] are the best solutions that scale from hobbyist to enterprise IMO. A few reasons: - Rook is "just" managed Ceph[2], and Ceph is good enough for CERN[3]. But it does need raw disks (nothing saying these can't be loopback drives but there is a performance cost) - OpenEBS has a lot of choices (Jiva is the simplest and is Longhorn[4] underneath, cStor is based on uZFS, Mayastor is their new thing with lots of interesting features like NVMe-oF, there's localpv-zfs which might be nice for your projects that want ZFS, regular host provisioning as well. Another option which I rate slightly less is LINSTOR (via piraeus-operator or kube-linstor[6]). In my production environment I run Ceph -- it's almost certainly the best off the shelf option due to the features, support, and ecosystem around Ceph. I've done some experiments with a reproducible repo (Hetzner dedicated hardware) attached as well[7]. I think the results might be somewhat scuffed but worth a look maybe anyways. I also have some older experiments comparing OpenEBS Jiva (AKA Longhorn) and HostPath [8].
