Given the wide variety of Linux environments, we prioritize development and testing on stable, supported kernels and distributions.

All longterm kernels from kernel.org are supported. stable kernels are usually supported in the next OpenZFS release.

Supported longterm kernels: 6.18, 6.12, 6.6, 6.1, 5.15, 5.10.

All RHEL (and compatible systems: AlmaLinux OS, Rocky Linux, etc) on the full or maintenance support tracks are supported.

Supported RHEL releases: 8.10, 9.7, 10.1.

All Ubuntu LTS releases are supported.

Supported Ubuntu releases: 26.04 “Resolute”, 24.04 “Noble”, 22.04 “Jammy”.

All Debian stable and LTS releases are supported.

Supported Debian releases: 13 “Trixie”, 12 “Bookworm”, 11 “Bullseye”.

Generally, if a distribution is following an LTS kernel, it should work well with OpenZFS.

All FreeBSD releases receiving security support are supported by OpenZFS.

Supported FreeBSD releases: 15.1, 14.4.
