FreeBSD 13+ threw away their faithful adaptation of production-proven code for OpenZFS (ZoL).[0,1] I refuse to use OpenZFS (ZoL) because a RHEL file server self-corrupted, wouldn't mount rw any longer, and ZoL shrugged it off without any resolution except "buy more drives and start over". Overall, there's grossly insufficient comprehensive testing tools, techniques, and culture in FOSS (FreeBSD, Linux, and most projects) rely upon informal/under-documented, ad-hoc, meat-based scream testing rather than proper, formal verification of correctness. Although no one ever said high-confidence software engineering was easy, it's essential to avoid entire classes of CVEs and unexpected operation bugs. 0: https://www.freebsd.org/releases/13.0R/relnotes/ https://www.freebsd.org/releases/13.0R/relnotes/ 1: https://lists.freebsd.org/pipermail/freebsd-fs/2018-December/027085.html https://lists.freebsd.org/pipermail/freebsd-fs/2018-December...

The link you posted explains exactly why they threw it away. You may disagree, but the stakeholders did not.

  Yes, I know. And I know iXsystems folks too. If you want stable, battle-tested ZFS, Solaris is the only supportable option on Sun hardware like the good ol' (legacy) Thumper. OpenZFS isn't tested well enough and there's too much hype and religious zealotry around it. For person use, it's probably fine for some people but, at this point, semi alternatives such as xfs and btrfs [thanks to Meta] have billions more hours of production usage.

    There are no checksums for data in xfs, and there is also no way to create a raid. There is also no data compression. Raid 5 and raid 6 are still unstable in btrfs. What alternative are we talking about?

Many mistakenly believe that FreeBSD took the ZFS implementation from Linux. It's not true, and it never was. OpenZFS is the result of merging code from illumos, Linux, and FreeBSD.
