The other replies answered most of your questions so I won't retread those. >Dm-integrity sounds worth a look, but https://raid.wiki.kernel.org/index.php/Dm-integrity https://raid.wiki.kernel.org/index.php/Dm-integrity doesn't inspire much confidence. That wiki page is pretty yikes - I was under the impression dm-integrity was farther along. Some misc other stuff I like about ZFS: l2arc/zil on ssd/optane devices for fast read/write caching Easy NFS/SMB sharing zdb ( https://manpages.debian.org/testing/zfsutils-linux/zdb.8.en.html https://manpages.debian.org/testing/zfsutils-linux/zdb.8.en.... ) I don't think you would be disappointed if you checked it out.
