My concern with ZFS is I use Fedora, so the kernel updates really frequently. I know that it kicks ass, but I just like having it straightforward in my kernel that I already have installed so that I never have to deal with a > If kernel module can not be loaded, your kernel version might be not yet supported by OpenZFS. An option is to an LTS kernel from COPR, provided by a third-party. Use it at your own risk: situation. (https://openzfs.github.io/openzfs-docs/Getting%20Started/Fedora/index.html)

Look, there is a reason *everyone* who actually knows this stuff use ZFS. A good reason. ZFS is really fucking good and BTRFS has absolutely nothing on it. It’s a toy in comparison. ZFS is the gold standard in this class. You have four sane options: - mdraid raid5 with BTRFS on top. Raid5 on BTRFS still isn’t stable as far as I know, not even in 2026. - Mirror or triple mirror with mdraid. Have the third drive in the pool as more redundancy or outside the pool as separate unraided filesystem. - Same as above, but BTRFS. Raid1 is stable. - ZFS RaidZ1 (=raid5) (Not sure about bit rot recovery when running BTRFS on mdraid. All variants should at least have bit rot detection.) To reiterate, *every* storage professional I know has a ZFS-pool at home (and probably everywhere else they can have it, including production pools). They group BTRFS with Ext3, if they even know about it. When I built my home server, the distro and hardware was selected around running ZFS. Distros without good support for ZFS were disregarded right away.
