Are there any good ceph alternatives? Why can't you use zfs directly?

  Ceph is distributed storage, ZFS is direct-attached to one host at a time.

  Yeah, there's a few but I haven't had a chance to give them a spin yet. I was mostly using Ceph to explore live migrations in Proxmox, although they just released support for ZFS based migrations(you have to migrate the whole local disk though so they aren't nearly as snappy). There's some pros to Ceph, mostly that you can add/remove drives at-will and the cluster will automatically rebalance. It's just very, very bandwidth hungry for cross-cluster communication. It doesn't matter that much since it's for a homelab, I could migrate to some 10Gbe links between the cluster at some point and it'll get snappier. ZFS is just such a solid, battle tested piece of tech that it's hard to beat it unless you have a very different set of constraints.
