I'm curious as to what advantage deduplication gives you on a home server? On a large file system with thousands of users, I can see how it could be a benefit there. But on my own computer, the large storage is taken up by photos, music, and video and I highly doubt there are many duplicate blocks there. I suppose if you're PXE-booting multiple computers with an NFS root file system, then deduplication could be of some benefit. Or maybe virtual machines. Some years ago, Red Hat was working on a system to kind of of do this, which they called "Stateless Linux[1]". I'm not sure if it's still an active thing or not. For me disk was too cheap to worry about this sort of thing.
