It's crazy to realize it has been ten years already since [1]Red Hat abandoned their Btrfs plans for Red Hat Enterprise Linux and dropped it, which was a technology preview feature since RHEL6. In its place Red Hat engineers began [2]developing Stratis for next-gen Linux storage with ZFS/Btrfs-like features but instead building atop XFS, LUKS, Device Mapper, and Clevis. After a while since the last major release, Stratis Storage 3.9 released today.

Stratis 3.8 [3]debuted in March 2025 and since then were various point releases while today was marked by the release of Stratis 3.9. The big change with Stratis 3.9 is now supporting online encryption/decryption/re-encryption. This online, in-place encryption handling of Stratis pools overcomes an existing limitation that up until now Stratis pools needed to be encrypted when the pool was initially created. Now you can decide to encryption or decrypt pools after initial creation. Or reencrypt a pool if wanting to change the key.

Stratis 3.9 also now allows starting a pool without its cache. Stratis 3.9 also moves its D-Bus layer from using dbus-rs to the Zbus crate, rewriting the stratis-decode-dm in Rust, and various dependency updates.
