That’s a fair concern. The closest thing right now is a deterministic simulation suite that injects storage faults and crashes at arbitrary points, then checks the recovered data against reference models. It runs hourly with fresh seeds.

CI also runs pjdfstest, xfstests, stress-ng, ZFS scrubs, and Jepsen crash/failover tests: https://github.com/Barre/ZeroFS#testing

ZeroFS is still pretty young as storage projects go, so I completely understand wanting to see it prove itself over time.

Why the hell was this answer dead? I vouched for it, because I don't see what might be wrong with it.
